ttn_hal: LMIC failed and stopped #67

Hi. I discovered your repository to assist me with getting my LoRa project off the ground, thank you for your work, but I am running into an issue with one of your examples - power_off. I am able to get hello_world and deep_sleep working properly but the power_off example always fails just as it begins to Join. Here is output as the ESP32S3 was reset.

E (422) ttn_hal: LMIC failed and stopped: ./components/ttn-esp32/src/lmic/lmic_us_like.c:51

I assume that all the examples use the same lmic_us_like.c file when compiling so why would the power_off example fail in this way but not the other two examples??

I can reproduce this problem. It is specific to American frequencies (and possibly similar ones). I'll investigate it further.

mdede439 commented 1 year ago

That's great! I have had similar issues like this before with other libraries. Unfortunately most of the LoRa code I want to use is developed in Europe and using frequency bands I can't use.

I appreciate you looking in to this.

A commit to the master branch likely fixes this issue.

I cannot fully test America frequencies. But I think I understood and fixed the bug, and it no longer occurs in my limited tests.

Thank you so much! I have verified that the updated library works with the power_off example code. I was even able to power my board via battery and pull the battery and reconnect it and the device was able to send another message without the need for rejoining!! For reference my setup was an Adafruit ESP32S3 with an Adafruit LoRa Feather and I was using ESP-IDF ver 5,02.

Thank you again for the quick work!!
