Mysensors and BSFrance Lora32u4 ii



  • I have recently bought 2 units of the board BSFrance Lora32u4 ii and I have been unable to get Mysensors library working with this boards.
    The boards seems to be a clone of Adafruit Feather 32u4 RFM95
    The board has a SX1276 radio module and the following pinout:
    0_1570905602169_LoRa32u4II_Pinout.jpg
    If I set a Serial Gateway (controller is Openhab in RPI3) with one of the boards and the other board as a node there is no message received in the gateway.
    The problem seems related to the reception (the transmission seems to work) because if i use as a gateway the board TTGO ESP32 Lora v2.0 I can see in the gateway logs some messages from the Lora32U4 node requesting to engage (Find Parent) and that the gateway replays but in the node the answer is never received.

    If I use RadioHead library with sender and receiver sketch with the 2 Lora32U4 boards, the transmission works perfectly in both directions (Transmission and Receptoin), so the hardware seems to be OK and I believe the problem may be with MySensors.

    Has anybody have any success with these boards and MySensors.

    I have used the development version of MySensors because I have TTGO boards with ESP32 processors and those are only supported by the development version, but I have also tried the latest stable version with the same results.

    I have also increased the timeouts for the ACK as suggested in the following post, although is quite old:
    https://forum.mysensors.org/topic/8813/any-success-story-on-lora-rfm95-module-and-mysensors/9
    I have included the configuration in the sketches instead of the library files as can be seen in the sketches. Is this right? or should I do that in the library files?:Mytransport.h and drivers/RFM95/RFM95.h.

    Welcome to the forum @CarloMagno
    Yes, the configuration should be in the sketches. Otherwise, the configuration would be overwritten for each upgrade of MySensors, and you would not be able to have different configuration for different sketches.

    I don't think the timeout should be an issue, since you are using one of the faster LoRa modes.

    I have never seen include <MyConfig.h> in a sketch before. Not sure if it has a negative impact.

    Looking at debug logs from the node and the gateway is likely the best way forward.

    @carlomagno said in Mysensors and BSFrance Lora32u4 ii:

    Not sure if it is relevant in your case, but there seem to be quite some revisions around of your board, according to this: https://www.thethingsnetwork.org/forum/t/big-lora32u4-boards-topic/15273



  • @mfalkvidd Thank you for the support.
    You are right, I forgot to post the logs, and without the logs I can imagine it is impossible to guess what is happening.
    Find attached the logs from the Node (Node 10 in this case) taken from the serial output connected to a computer, and the logs from the Gateway taken from the Controller (Openhab) web log viewer to which the gateway is attached through the serial port (Serial gateway):

    The logs from the gateway is a little bit more dificult to follow because of the lenght of the messages due to the heading from Openhab preciding the debug messages.

    Regarding the <MyConfig.h>, I believe it is because I have used it in the first MySensors implementation I did... some years ago (version 1.4) it was required.. I think.. and I have copied it in this new implementation.

    EDIT: The logs received in the Gateway is using the TTGO ESP32 Lora as gateway and Lora32U4 as Node. If I use another Lora32U4 as gateway no messages are received. With the TTGO at least I see that when I power the Node, the Gateway starts receiving messages indicating that there is communication and that the transmission part in the Lora32U4 is working.



  • @yveaux Thank you for the replay.
    I read that post when I was testing the board but I don't know much about radio protocols and I get a little confused trying to extrapolate the information in that post to MySensors. The boards I have are version v1.2 (printed in the PCB).
    What I understood from the post (I could be totally wrong), is that if I want to implement LoRaWan protocol with that board I would need to solder DIO1 and DIO2 to some IO pins (preferably pin5 and pin6 using wire instead of the 1 and 2 that would be the easy ones with the soldering pads). But I believe for radio use with MySensors (no LoRaWan) I don't have to solder DIO1 or DIO2... (Is this assumption right?) as I got the boards talking to each other with the RadioHead library and the pin definitions I posted the sketch.

    The receiver node got the message with this library and without soldering DIO1 and DIO2.
    Thanks again for the support!
