I have written a small script for my self where i poll the current usage periodically.
I write to service 0000fff0-0000-1000-8000-00805f9b34fb
to write the characteristics I use 0000fff3-0000-1000-8000-00805f9b34fb
to receive notifications I use 0000fff4-0000-1000-8000-00805f9b34fb
I send the commands identically to your script.
For this I use Java and https://github.com/weliem/blessed-bluez

I tried your suggested change
set HANDLE(req) 18
set HANDLE(notification) 20
But it is not able to write to the characteristic.

Is it maybe possible that the characteristics are not discovered and it defaults no permission?
I also recorded a hci log from my android device where i connect to the device.
btsnoop_hci.log
hope it helps.
from voltcraft-sem-6000.
I have taken a look at the attached btsnoop_hci.log
by using wireshark
As far as I can see you are right that the android app sends write commands instead of write requests:

... and so on.
May be the solution is just to change the handles (the commit that I have reverted) and the type of request as follows:
proc gatt_char_write_req { handle bytes } {
global DELAY
set hnd_hex [ decimal_to_hex $handle ]
set value ""
foreach b $bytes {
append value [ decimal_to_hex $b ]
}
log "INFO:\t>>>\tchar-write-cmd $hnd_hex $value"
send "char-write-cmd $hnd_hex $value\r"
expect {
"" {
log "INFO:\tOK"
}
# "Characteristic value was written successfully" {
# log "INFO:\tOK"
# }
}
I have committed this change. Can anybody double-check and confirm this?
from voltcraft-sem-6000.
@Heckie75 I don't have any new ideas on the historical data issue. As you mentioned, the official app suffers from the same problem. This would mean the official app is not fully functional in combination with the new devices. I would expect that a new app version and/or new firmware version will be released to solve this. I guess we'll have to wait for that before we can make progress on this issue.
@jrbergen Thanks for creating the usefull test script. I ran the script and took the liberty to make some small changes:
- Make sure the verbose output of the script also ends up in the logfile (by redirecting stderr of the script to stdout)
- Print the returncode of the script
- Add the historical data commands to the list of commands to test

Same issue here
from voltcraft-sem-6000.
It seems that handles are different in the firmware version. This is a problem since at this moment these are hard-coded.
Please do the following:

(decimal 43). In your case it is 0x0012
(decimal 18)
Get the handle for uuid 0000fff4
. In my case it is 0x002e
(decimal 46). In your case it is 0x0014
(decimal 20)
Open sem-6000.exp
with an editor. In line 180 and 181 change the handles to your values. Values are in decimal .
set HANDLE(req) 43
set HANDLE(notification) 46
Check if it works for you. I am going to change the code so that handles will be used dynamically.
from voltcraft-sem-6000.
I have changed the code so that hard-coded handles are removed and charactistics are read dynamically. Pls. double-check if this works for you.

This device now has firmware V1.16.
You have to know, that there are currently 2 issues with the devices (i purchase 3, they all have the same problems). With the "normal" App, i can not change the name of the device and the devices did not collect statistics. But i can see the current power consumption and can put it on or off.
best regards,

from voltcraft-sem-6000.
OK, in this case it seems that the problem is not only related to this script. Actually I have no Idea how to help. Sorry.
I also think that I'm going to revert the latest change.
from voltcraft-sem-6000.
BTW: Where have you read the firmware version?
I can see that there are two handles. In my case both is V1.00
[FC:69:47:06:CB:C6][LE]> char-read-hnd 1a
Characteristic value/descriptor: 56 31 2e 30 30
[FC:69:47:06:CB:C6][LE]> char-read-hnd 1c
Characteristic value/descriptor: 56 31 2e 30 30
Both is hex for "V1.00" (https://www.binaryhexconverter.com/hex-to-ascii-text-converter)
But according your output in terms of characteristics there aren't any handles for
- Firmware Revision (2A26)
- Hardware Revision (2A27)
Could you also double-check that the mac address matches the mac address connected in the official app?

I'm having the same trouble as @mniehren. I changed the handles as posted before.

from voltcraft-sem-6000.
From my POV I can´t really help since both of my devices have probably an older firmware and it just works. I think that there is a change related to authorization so that there are no notification events as long as there was some previous request.
The only way to find out is to sniff the communication between the official app and the device. This can be done by setting your android device into developer mode and activte bluetooth HCI-snoop protocol. Then use a tool like Wireshark in order to analyse communication.
The other - but illegial - option is to decompile the official app and take a look at the code.
BTW: Have you tried to pair the device by using bluetoothctl?
from voltcraft-sem-6000.
I ran into the same issue
I have two SEM6000 devices, one of them works fine with the script, the other doesn't work.
They both report firmware version 1.17 in the app
I ran the same commands on both devices using gatttool, using the different handles as mentioned above.

[A3:00:00:00:1B:F5][LE]>
Some observations:
- On the problematic device, using char-write-req gives 'Error: Characteristic Write Request failed: Attribute can't be written' error. However, char-write-cmd does work. (The sem-6000 script using char-write-req)
- The second command (reading a measurement) reports a different length on the problematic device (0f i.s.o. 11), while the actual responses have the same length.
- The last three commands (reading data for day,month and year) only return a single notification on the problematic device instead of multiple responses like on the working device
- The MAC addresses of the devices are very different, which makes me wonder if they might be based on a different hardware platform.
The first issue can be solved quite easily. The second and third issue however seem to be more problematic.
Any ideas anyone ?

I tried the code with your patch.
I used both --debug and --verbose to give you as much info as possible
The good news is that authentication is now successful.
Request device metadata works partially (requesting serial doesn't work)
Synchronize, capture measurement and request power consumption return an error (I didn't try any of the other commands)

I have changed s.th. so that there is an explicit authorization before synchronization. Pl.s check if it works now.
I have also changed s.th. so that simple measurement request should work now.
I have no solution in terms of requesting serial no.
If haven't analyzed the other problems yet.
Pls. check latest script.
May be you can try to activate notifications by doing the following:
$ gatttool -b B0:B1:13:61:B1:D1 -I

...
Look at the characteristic for notifcations with uuid fff4 and the it is the next line with uuid 2902. In my case the handle is 2f
Alternatively you can get the correct handle by searching for it ike this (2e is the handle of the uuid fff4):
[B0:B1:13:61:B1:D1][LE]> char-read-uuid 2902 2e
handle: 0x002f value: 00 00
Then enable notifications like this
[B0:B1:13:61:B1:D1][LE]> char-write-req 2f 0100
Characteristic value was written successfully
Please try to query historical measurement data. Do you get multiple notifications then?

Ok, according to the attached btsnoop_hci.log
the offical app has the same problem. There is also just a single notification per request.
Since I have seen that there is this "enabling notification request" I hoped that this would help.

But it is not the case. Any idea?
from voltcraft-sem-6000.
I don't have any new ideas (apart from adding learning about bluetooth protocol to the to-do list). However, I can confirm the same behaviour which @martijnwb described. I'm very happy that the "--measure" command works . Now I can simply send the data somewhere and do aggregation/statistics somewhere else.
In case it's useful for debugging; I wrote a small bash script to run the various commands and pipe it to some log file:

@martijnwb Nice adjustments; handige toevoeging. Will check the verbose output on my end sometime later. I suspect it'd be mostly equal to your output.
from voltcraft-sem-6000.
First of all, thanks to @Heckie75 for the great work. I have recently bought a SEM6000 and this project has been a goldmine of information (in particular, thank you so much for taking the time to write up API.md). In any case, it turns out I got the "new" version, so I thought I would share my observations in the hope that they will be helpful:
- A read on characteristic 0xfff1 returns
564f4c43465404000000000111030019
. I think byte 13 is the hardware revision, the new one has 0x03. It is possible that the different platforms do not share much code and behave differently even if both have firmware 1.17 (bytes 11, 12). - There is now a new version of the Android app that seems to work (4.18). A BLE capture is attached (app_v4_18.log).
- The new Android app requests an ATT MTU of 160 bytes after checking 0xfff1. The meter can then send a single long notification instead when requesting the history data. If you do not request a larger MTU, the default is 23 bytes and instead of splitting the data (like the old one does) it is simply cut off. iOS always negotiates the largest MTU possible and when they pushed the new firmware they may not have been aware that the same is not true for Android... (in fact some older phones may not support setting MTU at all)
- gatttool does support setting mtu. If I run
mtu 160
afterconnect
, it seems to work just fine. - Unfortunately, there seem to be some others quirks as well. The settings request (0x10) will return two additional null bytes that will make the script choke:
0xfff3 WRITE -> 0f051000000011ffff 0xfff4 NOTIFY -> 0f0e1000001cff0000007801000e6013ffff0000
- Also the length field for the measurement notification (0x04) is now set to 0x0f instead of 0x11 (the actual length has not changed). This does not seem to cause any immediate problems. But it means naively relying on it to solve the other problem may not work.
0xfff3 WRITE -> 0f050400000005ffff 0xfff4 NOTIFY -> 0f0f0400010022dae50061310100000000249e
- Not sure about the serial number. I have never seen the app requesting it. May be gone for good?

@switchabl
Thanks for these hints. I have added support for MTU but I am not able to test it.
I haven't changed the other quirks yet. Maybe later.

This is fully reproducible and not a transmission error (BLE has its own CRC checksum, so that is unlikely to happen anyway). My best explanation is that they somehow managed to break the checksum computation for this message. The app doesn't seem to care, I don't think it verifies the checksum at all.
Everything else I have tried seems to work, apart from --settings (and, for the same reason, --statistics) which fails because of the "0000 quirk"
