Gateway doesn't receive sensor data?

[rknse]

Hi!

I've downloaded FDRS and configured a simple system:

• LoRa sensor (D1 mini, RFM95/SX1276)
  #define READING_ID 0x10
  #define GTWY_MAC 0x01

• LoRa gateway 0x01 (D1 mini, RFM95/SX1276)
  #define LORAG_ACT sendSerial();
  #define LORA1_ACT sendSerial();

• MQTT gateway 0x00 (not yet connected)

The problem

The LoRa Gateway doesn't receive any data from my sensor, but it looks like it receives data from other nearby sensors...

Gateway output:

    Initializing FDRS Gateway!
    Address: 1

Sensor output:

[2] DR added to LoRa buffer. start: 11 end: 10
     LoRa sent.

     Delaying.

And just now I noticed that the sensor got "DR buffer overflow" after a while - but it still says "LoRa sent"?

I have tested the same setup with an ESPNOW_Sensor and an ESPNOW_Gateway and this works fine! Unfortunately, I can't use ESPNOW since the sensor would be out of range...

What am I missing? Can someone please give me a hint where the problem could be?

Hey @rknse,
Thanks a lot for trying it out. It does look like something's going wrong within the system itself. I'll test this tonight and get it figured out!

Fyi, the packets "not processed" are noise that gets registered as a packet by the SX1276 chip. It's normal, and they are probably not related to the issue.

@rknse, could you post the sensor serial output soon after it's powered up for about a minute or so of output? I assume you have LoRa ack's enabled? Those other packets received are not the correct length and thus they are not processed.

@aviateur17, below is the sensor output after a few minutes. The "NO ACK!" in the output shows that sendFDRS() always returns FALSE.

Hi @rknse,
Sorry for the delay, I just noticed I never got back to you about this. This was likely caused by a known issue which should now be fixed. Let me know if you still have issues after updating to the newest version of FDRS.

Hi Timm! I noticed your changes and downloaded the code immrdiately! Everything is working perfekt! I'm working on a battery powered node right now. Regards /Rolf Rolf Karlsson 070 771 4580 Den sön 7 juli 2024 20:26Timm Bogner ***@***.***> skrev:
