Problem joining using ABP #7

Closed xoseperez closed 6 years ago

xoseperez commented 6 years ago

Version: 1.02 Device: Arduino MKR WAN 1300 Code: FirstConfiguration.ino example

The FirstConfiguration example does not work when using ABP.

After some debugging, I found out that the set(DEV_ADDR, devAddr); in joinABP returns false always. Going a little deeper: the AT+DEVADDR=XXXX command times out in the waitResponse. After inspecting code from STM32 Cube Expansion LoRaWan I tried using AT+DADDR but got the same result.

OTAA works great.

Hi @xoseperez , I analyzed the bug and, indeed, the firmware is behaving incorrectly in case of ABP registration. I just pushed an updated firmware on https://github.com/arduino/mkrwan1300-fw/releases/tag/1.1.3 and I'm publishing the new library soon. Let me know if it fixes the issue for you!

That link goes to a 404. That repo does not exist, or maybe it's not public.

facchinm commented 6 years ago

It's public now, and it should have been since the beginning... However, you don't need that repo, simply update the libary (cloning master, I'm waiting for your feedback to release properly) and run MKRWANFWUpdate_standalone sketch

Cool, module version ARD-078 1.1.3 up and working.

Just one thing: out of the three tests I have done one gave an "Error sending message :(" but the message actually went through. Maybe the ACK?

facchinm commented 6 years ago

:+1: could you also confirm that OTAA is still working good? About the failing ACK, probably the timeouts are a bit too tight, I should increase them to avoid returning false negatives.

xoseperez commented 6 years ago

OTAA is working too. Thank you very much!
