1 year ago Thinking through the topic I guess I have found the right approach and understanding:
Joining the network has to be executed only once, like in step 2. After that the node has joined and does not need to join again.
With lorawan_is_joined() I can check if the node has joined.
With a slight modification of the example like the below, I can check if the node joined already and only if that is not the case execute the procedures to join.
if (!lorawan_is_joined()) {
// Start the join process and wait
printf("Joining LoRaWAN network ...");
lorawan_join();
while (!lorawan_is_joined()) {
lorawan_process_timeout_ms(1000);
printf(".");
}
printf(" joined successfully!\n");
}

I have this reproducable pattern: Step 1: I reset pico with flash_nuke.uf2 Step 2: I flash and run otaa_temperature_led.uf2 Step 3: I disconnect/reconnect power from pico and run otaa_temperature_led.uf2
Step 1 and Step 2 run flawless (DevEui is masked):
In step 3 the device cannot join:
The only point that helps at this point is restart at Step 1 from above. - or wait for an hour. Are those symptoms related to the gateway or the node? I am using RAK7289CV2. If a pro could give me a hint where to look next or some context I would be very grateful.
