Rak11300 - OTAA join failed!

[Famosi]

I'm trying to run the LoRaWAN_OTAA_ABP example for the Rak11300 core.

I'm getting the following error:

12:32:48.121 -> =====================================
12:32:48.121 -> Welcome to RAK11300 LoRaWan!!!
12:32:48.121 -> Type: OTAA
12:32:48.121 -> Region: EU868
12:32:48.121 -> =====================================
12:33:16.042 -> OTAA join failed!
12:33:16.042 -> Check your EUI's and Keys's!
12:33:16.042 -> Check if a Gateway is in range!

Check your EUI's and Keys's!: EUI and Keys are correct. Check if a Gateway is in range!: The Gateway is 1meter from the device.

I've registred the device on the helium console and I receive 3 Join Request replied with 3 Join Accept. Here is a screenshot: https://imgur.com/gallery/PExIFE6.

Note: I've also tried the example LoRaWAN_OTAA_ABP example for the Rak4631 core. In this case I have no problem. Everything works fine and I receive packets succesfully.

If you need more info let me know.

I updated the LoRaWAN examples for RAK11310 two days ago. https://github.com/RAKWireless/WisBlock/tree/master/examples/RAK11300/communications/LoRa/LoRaWAN/LoRaWAN_OTAA_ABP

Do you use the changed example?

There was as well a bug in the SX126x-Arduino library. ==> https://github.com/beegee-tokyo/SX126x-Arduino/releases

Please update to latest version 2.0.11

I was using an old version of the example. Now the device join succesfully :)

However, it should sends a frame every 20s but do not send it! It prints:

=====================================
14:30:26.425 -> Welcome to RAK11300 LoRaWan!!!
14:30:26.425 -> Type: OTAA
14:30:26.425 -> Region: EU868
14:30:26.425 -> =====================================
14:30:40.919 -> OTAA Mode, Network Joined!
14:31:01.883 -> Sending frame now...

but, if adding a cout at line 281 after this, it doesn't print anything.

I needed to make little changes to your code. In particular to the tx_lora_periodic_handler function.

Here is my working version:

void tx_lora_periodic_handler(void)
{
  send_now = true;
  appTimer.attach(tx_lora_periodic_handler, (std::chrono::microseconds)(LORAWAN_APP_INTERVAL * 1000));
}

Does it makes sense to you?

That is one of the problems with the RP2040 BSP. It needs sometimes such workarounds because it is based on mbed.

Glad you could solve it.
