Hi Congrats and thanks for making it open source.

1. Can you please share the BOM file (bill of materials)

2. Please update LoRa-concentrator/Version2/RPI/SCH.pdf some of the labels of components are overlapped

3. What is the procedure to change it to 868 mhz

Getting line 8, column 16: This is not an EAGLE file. error with Radio_RPIv15_915.sch

Hi i want adapt and make changes to this board for India IN865
Will it be sufficient to change following filters:
U$8,U$4,U$9 and
U$6
if yes what would proper value/model number for it.

and do we need to change any other component.?

Congrats and thanks for the great project!

I'm interested to build a SX1255 433 MHz Version2 RPI card. As you suggested in the readme, I found the matching components values for TX part in the SX1255 datasheet.

However, since the RX path is shared between 2 SX1255 radios, I suppose the matching components will be different from datasheet. Could you please share with us the components values for RX path matching in that case? Could you push a .sch file for that case (Version2 RPI, 2 SX1255 radios)?

Thanks

Hi,

I see in your schematic you are using a XC6204 voltage regulators for 1.8 and 3.3 outputs from a 5v source.
This regulator has only 150mA max output current. This is insufficient.

SX1301 need 550mA typ, 750mA max @ 1.8v and 5mA typ, 10mA max @ 3.3v.

Even if you put a bigger LDO with 1A or more, the LDO will get very very hot, it will dissipate (5-1.8)*0.55= 1.76W of energy in hot.
I recommend to use a (step-down, DCDC converter...) switching regulator not linear regulator.

Hello, I have download your project and found that I can't get the value of Resistance, capacitance, inductance.Could you please show me you BOM?Thank you!

Hey will and friends,

First of all this is a great project, I will build one or two GW's for learning, but my question is:

• Have you bought the components from BOM on Mouser?
• Maybe have an updated list with PartNumbers so I can buy the exact same components from the original project?

After build, I can configure it to run on AUS frequencies?

Thanks all!

Hi! I'm interesting this project, I need to create a simple gateway for LoRa.
How to use this board? I mean, this is project, as I understand, provides the physical layer, what I should use to connect this layer to LoRa server?
For example, I found the project group LoRa-net on github, I installed and setup LoRa-Gateway-Bridge, LoRa-Network-Server and LoRa-Application-Server on VirtualBox.
How to put it together?

I have an error similar to that; #33

I have Version 3 of LoRa Concentrator, this is so good Gateway for using LoRaWAN with TheThingsNetwork for PoC.
I examined this on RPi3(Latest Raspbian Desktop), however it doesn't run successfully.

We can found this wiki; https://github.com/will127534/LoRa-concentrator/wiki/Startup-Guide
I got below error at first step(2.5A supplied);

Who do know or can solve this?

Testing Setup: one Transmitter @ 433.5Mhz, config Radio_B to 433.2Mhz and two channel with IF 0Khz and +3Khz.

Problem: the transmitter is transmitting package one per second (confirm by other SX1278), but SX1301 cannot receive package reliably, receive a package for a couple seconds, as the log show below.

The problem may cause by

1. Unstable Crystal (I'm using normal OSC now)
2. missing inductor at SX1255 input RF
3. missing SAW

So currently I'm going to get some TCXO, inductor, and SAW to see if any of them helps.

你好!
433Mhz 和470Mhz，除了把SX1257换成SX1255，还需要对哪些元件进行更换呢？ 麻烦指教。

Hi,

Great work you have done so far. I also wanted to try to create a gateway myself then I stumbled on your project. I have gone through the LoRaGW userspace C code and currently they use the Ublox GPS sensors as it outputs raw GPS time, not UTC. I have not yet confirmed what the GPS time is used for but your project has motivated me to check up on it later today. Do you have info on this?

As to my questions:

1. I have some Quectel L96 and L80 parts and the most they do is give UTC time. Did you have to change the codebase to accept the quectel version NMEA strings?
2. Any plans to do a PoE version? That would be something interesting and I would be willing to look into.

@will127534 Hi!
I use GPS on the board version 3 with external antenna.
I see log messages:
### [GPS] ###
# Valid time reference (age: 0 sec)
# no valid GPS coordinates available yet
##### END #####
There is no valid coordinates for a long time. Why I didn't see them at all?

I misplaced/lost the LoRa SMA antenna. I would like to buy a new one from local market, what's is dBi for this?

Hello,

I can't find the part number for the crystal oscillators used for SX1255 and SX1257. Can you tell me which one you used in the design?

The datasheet of SX125x IC states that it must be 1.8V peek to peek sinewave. Adding capacitor in series might solve this, however the maximum voltage would still be 3.3V relative to GND. Don't know if this is OK or I am missing something.

Thanks

Not sure what happened, but it keeps notify this error

lgw_start:845: Note: calibration finished (status = 197)

Hi, i am interested in such concentrator for long range temperature humidity measurements (SHT21), i notice all values are removed, any chance you update the file or follow b email?
Thank you.

Thanks for your great design!

I'm currently picking all the parts to build my own full size V3. I have a few questions about some of the components:

L7 has a value of 8.2uH in a 0402 package. Is this really correct?
C21 is EOL and no longer available. Can I choose a different part? What are the requirements for the component?

Could you provide me with the components you use for botch oscillators? I have a hard time picking a correct model.

Thanks!

hi will
when i bot the SX1308 Raspberry Pi Lora Gateway i have chosen the 868 MHz, i wanted to ask if by simple changing the Antenna to 915 Mhz will it be possible to use it as a Lora concentrator with a frequency plan of 915 MHz after configuring the global_conf files to 915 MHz.

if that's not possible you mentioned that the difference between the 868 model and the 915 model is simply 4 filters that we need to change, so is it possible to share the BOM file for the 868 MHz.
thank you have a great week.

I've got the LoRa-concentrator (the board version 3), EU868 configuration.
My LoRaWAN-mote sends messages, radio0 (ch0, ch1, ch2) receives them with RSSI -27, but radio1 (ch3, ch4, ch5, ch6, ch7) receives them corrupted only on ch5 with RSSI -111.
Thus only 3 from 10 messages reaches my server.
Is it a hardware problem? Maybe the board is damaged?

Im trying to figure out right parts for this design.
Im sharing this BOM from Octopart, if any one can suggest if its ok, it will be good to buy the item.
https://octopart.com/bom-tool/LadeLROL

Great project, Merge the gateway with Raspberry pi is a good idea.
Is NDA going to be a problem?And what's the progress and roadmap?

JP1 allows selecting between SPI 0.0 and SPI 0.1. If I wanted to use SPI 0.1, what do I have to update to have the raspberry PI see the concentrator?

Hi,
Since the production stopped, I printed my own PCB without no changes in the given schematics. When I test it, I still get "main: LoRa concentrator failed to start".

Am I missing something!?

as titile.

Currently this board still stuck on this problem,
Register Test passed, and I can confirm that the firmware is correct.
Here is the test_loragw_reg result.

Still not sure were the problem is, by looking at the SPI bus it seems the data is right,
it really sent out 176 when reading register.

I'm not a RF design expert, but shouldn't RF RX paths (N$49 at your schematic for v3) be merged using some impedance matching ? Integrated resistor divider (losses >= 6dB) or Wilkinson divider (losses >= 3dB). They cost pennies (~$0.3).

Setup:
one RF98 Transmitter @ 432Mhz, transmitting 6-axis data (24byte+2byte header) per 100ms
one RPI-Gateway with full channel on

If I tested indoor, Gateway will output some error data, the full log is here

it seems that SX1301 will output some wrong data.

But I when I try it near the window(with some wind), the error goes away, so I believed that it is cause by thermal problem, maybe do some measurement later.

I've already added a heatsink on top of SX1301, but it seems not enough....

An interesting deployment is together with PoE (802.3af) through the official PoE Hat for the RPi 3 B+. Is this board compatible with that Hat?

Awesome project, eagerly awaiting an 868 model.

Hi,
I am having this error as shown below from a long time. It got solved once when a good power supply was provided but having it again. I always do the reset as told.

I can nit message you here.
Please contact me on [email protected]
Thank you.

First and foremost, huge thanks to the author @will127534 for all the work!

I'm trying to get the BOM ready and send the design to jlcpcb. Wondering if anyone made this recently so that we can share some resources.

Capacitators have voltage ratings, e.g. 5v, 10v, 25v, 50v.*

Which one do you recommend? Is 16v enough or better 25v to be sure?

Also: M15 (CAP-0402) has a value of 1K? Is that a special capacitor?

1nF = 1000pF so M5, M17 and C19, C34 are the same, right?
C3 is the same as C1, C23, C24, C35?

Sorry, my electronics knowledge hasn't been used for decades.
Thank you for your great work!

What is the reason that you switched from four antennas in version 1, to one antenna in version 3?

I managed to get the system running and ran it say 5 times with no errors and was about to work out why the connection was not showing on the Things network when I got the error message "failed to start the concentrator".
command run was
./lora_pkt_fwd > logfile.txt

Is there a list of things to check? It seems odd that is was working one minute and not the next. [The only thing I did was shut it down to swap over the power supply for the Raspberry Pi because I was getting low voltage warnings, which in itself was a bit odd because the voltage was 5.1V and it was a 2A supply providing 300mA. Anyhow swapped PS. I wasn't sure this was a Raspberry Pi voltage error and not one from the LoPoWAN board?]
Is there a list of things to check with the LoPoWAN setup, everything was done as per the instructions.
Up to the end of the TTN network setup guide.

Unfortunately I don't have a log from when it used to run but I know it was quite a few more lines, the GPS went on and off and then it was doing a few push commands or something.
json files attached.

I thought that LoRa gateway support normal GPS with NEMA output,
but it seems to support only uBlox module, because it is using uBlox's UBX protocol for time adjustment.
So it might needs to change to uBlox module(MAX-7 series maybe) in the future.

There are still questions:

1. The project design does not include the names of TXCO. Are there any requirements for their characteristics, such as accuracy or stability?
2. What were the requirements for the motherboard material or did the conventional FR-4 take it for the board?

Thanks.

Hello, @will127534! Do you have an official library for this board and some examples to go with? Thanks!

I was using your board V3 with my rpi for a looong time.
I just migrated to ttnv3 and using t-impulse watch to do some tests. The packet forwarder seems to register right in TTN but when the watch tries to register we send back a bad message to the watch. I suppose that's a gateway trouble, because the libraries are open, ttn is tested by thousands and the only piece in the middle is the gateway...

arduino-lmic sees the message but ev_t ev value enum is strange and changes in every registration...

See something like 1257164: Unknown event

Do you think that packet forwarder or gateway library is still ok?

It seems that HAL from SEMTECH supports LBT when version is > = 4.1.0, but can AS923 be supported by your board ? (Japan)

When will the LoRa concentrator, 868MHz be on sale over Tindie??

Would it be possible to replace the Max-7Q with the pin compatible Quectel L70. It outputs a 100ms 1 PPS signal but only supports NMEA output.
This would significantly reduce the price (5$ vs 25$)

I've run util_spi_stress successfully for multiple hours. We have ordered the bare PCB and assembled the board. Any ideas what the problem can be?
