sllurp's Introduction

https://circleci.com/gh/ransford/sllurp.svg?style=svg

sllurp is a Python library to interface with RFID readers. It is a pure-Python implementation of the Low Level Reader Protocol (LLRP).

These readers are known to work well with sllurp, but it should be adaptable with not much effort to other LLRP-compatible readers:

Impinj Speedway (R1000)
Impinj Speedway Revolution (R220, R420)
Impinj Speedway xPortal
Motorola MC9190-Z (handheld)

File an issue on GitHub if you would like help getting another kind of reader to work.

sllurp is distributed under version 3 of the GNU General Public License. See LICENSE.txt for details.

Quick Start

Install from PyPI:

$ virtualenv .venv
$ source .venv/bin/activate
$ pip install sllurp
$ sllurp inventory ip.add.re.ss

Run sllurp --help and sllurp inventory --help to see options.

Or install from GitHub:

$ git clone https://github.com/ransford/sllurp.git
$ cd sllurp
$ virtualenv .venv
$ source .venv/bin/activate
$ pip install .
$ sllurp inventory ip.add.re.ss

If the reader gets into a funny state because you're debugging against it (e.g., if your program or sllurp has crashed), you can set it back to an idle state by running sllurp reset ip.add.re.ss.

Reader API

sllurp spawn his own "thread" to manage network interaction with the reader. To make a connection, create a LLRPReaderClient and connect() it:

# Minimal example; see sllurp/verb/inventory.py for more.
from sllurp import llrp
from sllurp.llrp import LLRPReaderConfig, LLRPReaderClient, LLRP_DEFAULT_PORT
import logging
logging.getLogger().setLevel(logging.INFO)

def tag_report_cb (reader, tag_reports):
    for tag in tag_reports:
        print('tag: %r' % tag)

config = LLRPReaderConfig()
reader = LLRPReaderClient(host, LLRP_DEFAULT_PORT, config)
reader.add_tag_report_callback(tag_report_cb)

reader.connect()
# We are now connected to the reader and inventory is running.

try:
    # Block forever or until a disconnection of the reader
    reader.join(None)
except (KeyboardInterrupt, SystemExit):
    # catch ctrl-C and stop inventory before disconnecting
    reader.disconnect()

Note

Sllurp used to depend on python twisted and was using its mainloop. This is not the case anymore. Once connected to a reader, Sllurp will spawn his own "thread" to process the received messages and to call user defined callbacks. is_alive() and join(timeout) thread api are exposed by the LLRPReaderClient instance.

Getting More Information From Tag Reports

When initializing LLRPReaderConfig, set flags in the tag_content_selector dictionary argument:

llrp.LLRPReaderConfig({
    'tag_content_selector': {
        'EnableROSpecID': False,
        'EnableSpecIndex': False,
        'EnableInventoryParameterSpecID': False,
        'EnableAntennaID': True,
        'EnableChannelIndex': False,
        'EnablePeakRSSI': True,
        'EnableFirstSeenTimestamp': False,
        'EnableLastSeenTimestamp': True,
        'EnableTagSeenCount': True,
        'EnableAccessSpecID': False,
    }
})

Logging

sllurp logs under the name sllurp, so if you wish to log its output, you can do this the application that imports sllurp:

sllurp_logger = logging.getLogger('sllurp')
sllurp_logger.setLevel(logging.DEBUG)
sllurp_logger.setHandler(logging.FileHandler('sllurp.log'))
# or .setHandler(logging.StreamHandler()) to log to stderr...

Vendor Extensions

sllurp has limited support for vendor extensions through LLRP's custom message facilities. For example, sllurp inventory --impinj-search-mode N allows you to set the Impinj search mode to single target (1) or dual target (2).

Handy Reader Commands

To see what inventory settings an Impinj reader is currently using (i.e., to fetch the current ROSpec), ssh to the reader and

> show rfid llrp rospec 0

The "nuclear option" for resetting a reader is:

> reboot

If You Find a Bug

Start an issue on GitHub! Please follow Simon Tatham's guide on writing good bug reports.

Bug reports are most useful when they're accompanied by verbose error messages. Turn sllurp's log level up to DEBUG, which you can do by specifying the -d command-line option to sllurp. You can log to a logfile with the -l [filename] option. Or simply put this at the beginning of your own code:

import logging
logging.getLogger('sllurp').setLevel(logging.DEBUG)

Known Issues

Reader mode selection is confusing, not least because most readers seem to conflate ModeIndex and ModeIdentifier. If you're using sllurp inventory, use --mode-identifier N. Check your reader's manual to see what mode identifiers it supports via the C1G2RFControl parameter, or run sllurp --debug inventory against a reader to see a dump of the supported modes in the capabilities description.

Authors

Much of the code in sllurp is by Ben Ransford, although it began its life in August 2013 as a fork of LLRPyC. Many fine citizens of GitHub have contributed code to sllurp since the fork.

sllurp's Issues

Basic tags reading

Hello,

I know it's maybe stupid question, but we can't get it at all.
We want to use Sllurp in our app and read every tag that is in antena range. So when tag is in range we check it for example every second and put it to array so we could use this information next.

Basically our problem is that when we try to read tags by sllurp command or by using code connection we just get only tags that are new to reader. So easily saying tags that where read before don't get read any more. What we do wrong?

TransmitPower out of range with some readers

The TransmitPower setting is reader dependent.

2014-01-14 17:25:04,208 sllurp: INFO: total # of tags seen by callback: 0

The correct fix is to issue a GET_READER_CAPABILITIES and receive & parse the GET_READER_CAPABILITIES_RESPONSE before adding any ROSpecs. TransmitPower goes up to 91 on the Speedway Revolution, for instance, but only 61 on the original Speedway.

TX power handling is totally wonky

Big mess in llrp.py. Simplify!

Modulation problem

Hi, I tried to use R420 reader to communicate with my WISP5 tag. My command line was this

sllurp inventory -M WISP5 -T 7140 (my reader's ip address)

But unfortunately I got this massage

WARNING: Could not find reader mode matching modulation=WISP5 and Tari=7140

And sllurp just ignore my modulation setting. I tried other modulation settings like FM0 or M2 etc but none of these are working.

Can you help me out with this problem?

Fix parameter shifting bug.

When startAccess is called from another function, sometimes the parameters of startAccess would be shifted to the right for no apparent reason. This also happens when changing accessSpecs frequently and can be seen by this log message:

2015-02-17 16:58:11,477 sllurp.llrp: ERROR: panic(): ('ADD_ACCESSSPEC failed',)
2015-02-17 16:58:11,477 sllurp.llrp: ERROR: 6
2015-02-17 16:58:11,477 sllurp.llrp: ERROR: Traceback (most recent call last):
Failure: builtin.int: 6

Basically, it received the STATE of the system instead of the real 1st parameter of startAccess causing the weird behavior.

Switch to more permissive license

Goal: BSD or MIT license.

We inherited the GPL from LLRPyC (and updated it to v3 along the way). This license makes it difficult to include sllurp in software that can't be open sourced for whatever reason.

https://tldrlegal.com/license/gnu-general-public-license-v3-(gpl-3)

The way forward is to expunge all LLRPyC source code, which at this moment is just the protocol messages in llrp_proto.py, in favor of novel code that we can license differently. The construct branch is well underway but isn't yet the default way of handling LLRP messages.

Once the expunging is done, we can make a new release under a new license.

Writing a word in a user memory bank and reading the word

I have no idea...

I am just a beginner. Can someone point me where to start? I will be very thankful :)

Support PerAntennaAirProtocol parameter

See section 17.2.3.1.4 of the LLRP 1.1 spec. This is part of the GeneralDeviceCapabilities message and appears on Motorola readers.

malformed ADD_ACCESSSPEC message

@lqf96 reports that, with the code in https://gist.github.com/lqf96/5addd0962cabbfbce728711785aa4ddf, sllurp (presumably the latest develop) produces the following ADD_ACCESSSPEC message and response:

... with a clear bug in the DataBitCount parameter of the C1G2TargetTag param.

Update Tornado example

The Tornado example is useful but hasn't been updated in a while; some API changes broke it.

Creating ROSpec from template file

Wouldn't it make sense to do the ROSpec / antenna config / capabilities building from a template file and then load it via json.loads() at

https://github.com/ransford/sllurp/blob/master/sllurp/llrp_proto.py#L2117
https://github.com/ransford/sllurp/blob/master/sllurp/llrp_proto.py#L2161
https://github.com/ransford/sllurp/blob/master/sllurp/llrp_proto.py#L2077

It would save ~70+ lines and make it much more readable / configurable.

Implement stream-like read/write functionality

Making use of blockWrite, please implement a stream-like read/write functionality to write a huge chunk of data to the wisp or read a huge chunk of data from the wisp.

Support multiple antenna power settings (map)

#54 has been available for almost a year but has not yet been merged due to conflicts. I have a need to support multiple antenna power settings and was about to do a pull request for this feature when I noticed there is already one sitting there with basically the same changes I had made. Can you please resolve the conflicts and add this in to the main branch?

Thanks!!

ThingMagic Sargas: Unsupported StopTrigger 3

Support for Python 3?

Both the sllurp CLI and the library fail to run under Python 3.6. Since official support for Python 2 is going to end at 2020, maybe we should update the code to make it work with Python 3.

Get info from the reader

Hi ransford,

I'm on a project to build a tag based management system that runs on the web, and I use Sllurp to get data from tags, that's cool!. all is working well. I haven't much knowledge about RFID systems and I'am a beginner of python, I just want you ask a simple question, is possible to get data from reader inside the TagReportData?

What happens is I got two readers, I am reading from both an listing the tags, I get the antenna id from each reader, no problem. But I need to know from where reader comes data.

I mean maybe host IP, mac address or some id that identifies a reader. If this can be done, how can I get that data into tag data returned by the report?.

I tested these parameters but no one distinguishes one reader from another

                                 'EnableROSpecID': True,
                                 'EnableSpecIndex': True,
                                 'EnableInventoryParameterSpecID': True,
                                 'EnableAntennaID': True,
                                 'EnableChannelIndex': True,
                                 'EnablePeakRRSI': True,
                                 'EnableFirstSeenTimestamp': True,
                                 'EnableLastSeenTimestamp': True,
                                 'EnableTagSeenCount': True,
                                 'EnableAccessSpecID': True

I appreciate your answer, sorry for my english, is not my native language.

Thank you.

Unify command-line tools

Into a single sllurp command. click can help with the CLI heavy lifting.

In the process, fix setup.py (doc) and use an entry_point.

All this grooming will help with #6.

Antenna configuration problems

Hi! I have some problems to configure the antennas in my LLRP reader, in order to run a simple inventory. I would like to receive only data from antennas 5, 6 and 7. Then, I'm running the inventory like this:

python inventory.py -t 2 -a 5,6,7 10.0.1.57

When I do this, only receive data from the first antenna that I set up, in this case, the 5.

If I see the LLRP packets, in the ADD_ROSPEC message, I can see that the Antenna Configuration is correct:

And the ADD_ROSPEC_RESPONSE is Succes:

But I only receive 'Reader Event Notification' messages from the first antenna configured:

One card of five is not detected as often

Speedway R640

One of my five test cards under-reports. I discovered the problem with my own software (a horrible fork of yours for the time being), where the issue was much worse for some bizarre reason. The problem does not occur with the Multireader software from Impinj. I just have five cards on the desk in front of the reader.

Your program, with a bit of script-fu, I hope I am doing that right.

List reader modes and exit

In #64, it would have been helpful to have a --list-modes option to fetch the reader's capabilities blob and print the available mode settings. Right now it's necessary to call sllurp --debug inventory <ip.add.re.ss>, find the capabilities section, and dig through it to find the mode settings we want.

Support manufacturer extensions

Motivating case: Impinj readers make phase-angle information available in tag reports: https://support.impinj.com/hc/en-us/articles/202756348-Get-Low-Level-Reader-Data-with-LLRP

Simplify conversation in reset operation

bin/reset shouldn't request capabilities; whittle down the post-connection sequence to the bare minimum.

CSV logging doesn't make sense

Quick & hacky sllurp log stinks. How should logging to CSV work?

One CSV line every n milliseconds
Include count of tags with each line
File should be tail-able, not dumped at end

implement CLOSE_CONNECTION for graceful shutdown

As specified in 13.1.5. The current "polite" behavior is to delete all ROSpecs, but this way is even more polite. Execute CLOSE_CONNECTION and wait for CLOSE_CONNECTION_RESPONSE after deleting all ROSpecs.

Parsing of tag data

Hey Ben, I'm not sure if this is out of scope, but I whipped up this SGTIN-96 parser last night. Happy to include it in Sllurp if you think it'd be useful.

Trouble reading temperature sensor data from EM 4325 IC

Hi
EM 4325 IC has the on board temperature sensor on it. I am trying to read the 256th word in its user memory bank using the access.py .However, I am not understanding this tag read rata. Here is it for example:

2018-05-11 16:01:42,200 sllurp: INFO: saw tag(s): [{'AccessSpecID': (1,),
'AntennaID': (1,),
'EPC-96': b'0080b0443c0000001210b4b6',
'LastSeenTimestampUTC': (1526056288899394,),
'OpSpecResult': {'OpSpecID': 0,
'ReadData': b'\x00^\x00\x00',
'ReadDataWordCount': 2,
'Result': 0},
'PeakRSSI': (-49,),
'TagSeenCount': (1,)}]

Why is it reading \x00^\ does this mean there is a decoding issue? But it works well if I am reading any other data for example EPC code. I have tested reading using the impinj's multi reader software and it works perfectly fine. So I am guessing something is not happening right when I use Sllurp.

Did anyone successfully read EM 4325's temperature data using sllurp?

Also, how do I selectively read only one tag from access.py instead of reading all tags. Thanks for your help in advance.

Targeted Antenna Tag Readings

Hello!

I am using Impinj R420 Reader. Everything is working fine until I tried to the scenario below:

My setup, I place:

EPC: 3039606343b916c000154213 on antenna#1
EPC: 30396062c3b02440000002ee on antenna#2

Below is the command i used and result given:

sllurp inventory <reader ip> --antennas 2

sllurp.verb.inventory: INFO: saw tag(s):
[{u'AntennaID': (2,),
u'EPC-96': '3039606343b916c000154213',
u'LastSeenTimestampUTC': (1508917299346036,),
u'PeakRSSI': (-34,),
u'TagSeenCount': (38,)},
{u'AntennaID': (2,),
u'EPC-96': '30396062c3b02440000002ee',
u'LastSeenTimestampUTC': (1508917299345483,),
u'PeakRSSI': (-53,),
u'TagSeenCount': (38,)}]

Instead of getting one RFID's EPC, i'm getting both.
Is there a configuration for me to disable antenna#1 while antenna#2 is scanning?

Thank you!

Hardcoded ModeIndex breaks communication with WISP5

The value of mode_index (sllurp/llrp_proto.py) has been hardcoded to a value of '1000', breaking communication with WISP5 which requires a value of '0'.

Support for ThingMagic Astra-EX reader

Hi Folks. I'd like to get sslurp working with the ThingMagic Astra EX reader (http://www.thingmagic.com/index.php/integrated-readers/445-astra-ex). The reader specs state that it supports "LLRP v1.0.1 with multi-protocol extensions". Here's what I get when trying to use inventory "out-of-the-box":

Any help is much appreciated. The "Mercury" API that ThingMagic supplies only supports Java, C and C#. I could probably generate python wrappers for the C interface but if I can get sslurp working, that will save me a lot of time.

Trouble with rswr-400 reader

Hi,

I'm currently having problem when running sllurp inventory ip.add.re.ss. I'm using the rswr-400 reader from Radiant Sensors. From what I can see, there is a problem with ADD_ROSPEC_RESPONSE but I have no clue how to resolve this.

Here is the --debug result: https://pastebin.com/B6Cn7K5x

Help would be greatly appreciated.

Thanks!

I'll create a PR fixing these.

Error unexpected response DELETE_ROSPEC_RESPONSE

This is the error we chatted about - I'm immediately disconnecting (to delete any existing ROSpecs) like so:

def clear_rospec(proto):
    if not self.initial_rospec_clear:
        logger.info('rfid clearing rospec')
        self.initial_rospec_clear = True
        return proto.stopPolitely()

fac = LLRPClientFactory(**config)
fac.addTagReportCallback(tag_seen_callback)
fac.addStateCallback(LLRPClient.STATE_CONNECTED, clear_rospec)

And here is the output, from starting to the error, to inventory starting. I've replaced the content of , its NUL values were causing problems.

remove LLRPReaderThread

The thread<->reactor relationship is too hard to get right. Base everything on the reactor's async event model instead.

Restructure protocol conversation around defer.inlineCallbacks

Twisted's defer.inlineCallbacks helps the reactor not block, which is a pain point right now when talking to {slow, many, misbehaving} readers.

Decode User Memory

Similar to how decoding EPC works, it would be super useful to be able to have an API to decode user memory as it's done here:
www.gs1us.org/resources/tools/user-memory-encoder-decoder

Unbreak duration arg

Specifying LLRPClient.duration used to make LLRPClient call stopPolitely() after duration seconds, but since 7fd2559 we repurposed this duration member variable to control reporting period instead. This is a mess.

Lost Connection: Unpack requires a string argument of length 10

A frequent error has been occurring while running sllurp and causes a connection timeout. It seems that there is an issue with unpacking data and results in the error 'unpack requires a string argument of length 10'. I'm not sure what steps to take to resolve the issue. Below is copy of the error received,

Declarative parsing of protocol messages

There's a huge amount of redundancy in the message encoding and decoding routines. Each message type currently has its own functions that pack & unpack binary representations -- including headers and other redundant stuff.

The right solution is to do most of the encoding and decoding work in a generic function that obeys a separate specification of message formats. This work is already started in the messages branch.

Upload to PyPi

Hello!

It would be great to see the package up on PyPi. The procedure is as follows:

pip install --upgrade pip
pip install wheel
pip install twine
python setup.py sdist bdist_wheel

#dist/ should now contain 2 files (.whl, .tar.gz)
twine upload -u USERNAME -p PASSWORD dist/*

It would make sense for the author of this package, @ransford, to upload this to https://pypi.python.org/pypi

Thanks!

Getting TID from RFID tags through LLRP readers (although not Impinj).

Hi! I would like to get the TID from the RFID tags through any LLRP reader (although not Impinj).

First of all, I don't know if it is possible, because I've seen that this data is requested in a Custom Parameter by the Octane SDK (Impinj) in LLRP frames. Any idea? Example:

Secondly, if I can request this data from any reader through a Custom Parameter in the ROSpec, how could I do it? I started the implementation of this field but I have some problems.

First, I defined the Custom Parameter struct:

Message_struct['CustomParameter'] = {
    'type': 1023,
    'fields': [
        'VendorID',
    #    'Subtype',
    #    'CustomParameter'
    ],
    'encode': encode_CustomParameter
}

Second, I've implemented the encoding function like yours:

def encode_CustomParameter(par):

    msgtype = Message_struct['CustomParameter']['type']

    msg_header = '!HH'

    flags = 0
    i = 15
    for field in Message_struct['CustomParameter']['fields']:
        if field in par and par[field]:
            print(field)
            flags = flags | (1 << i)
        i = i - 1

    data = struct.pack('!H', flags)
    data = struct.pack(msg_header, msgtype,
                       len(data) + struct.calcsize(msg_header)) + data

    return data

And then, I added the new field to the 'ROSpec':

# 16.2.7.1 ROReportSpec Parameter
def encode_ROReportSpec(par):
    msgtype = Message_struct['ROReportSpec']['type']
    n = int(par['N'])
    roReportTrigger = ROReportTrigger_Name2Type[par['ROReportTrigger']]

    msg_header = '!HHBH'
    msg_header_len = struct.calcsize(msg_header)

    data = encode('TagReportContentSelector')(par['TagReportContentSelector'])

    custom = encode('CustomParameter')(par['CustomParameter'])


    data = struct.pack(msg_header, msgtype,
                       len(data) + len(custom) + msg_header_len,
                       roReportTrigger, n) + data + custom

    return data

Message_struct['ROReportSpec'] = {
    'type': 237,
    'fields': [
        'N',
        'ROReportTrigger',
        'TagReportContentSelector',
        'CustomParameter'
    ],
    'encode': encode_ROReportSpec
}

[...]

'ROReportSpec': {
                # XXX this does *not* cause the reader to produce
                # RO_ACCESS_REPORT messages every 1s, as it looks like it
                # should; instead they appear much more frequently.
                'ROReportTrigger': 'Upon_N_Seconds',
                'N': 1,
                'TagReportContentSelector': tagReportContentSelector,
                'CustomParameter': {
                     'VendorID': 25882,
                    # 'Subtype': 50,
                    # 'CustomParameter': {
                    #     'VendorID': 'Impinj',
                    #     'Subtype': 51,
                    #     'SerializedTIDMode': 1
                    # }
                },
            },

Finally, the reader replies that there is an error with any of the fields:

Could you help me a little bit? :)
Thank you!
