Sending wrong Device EUI and Join EUI about lorawan-library-for-pico HOT 10 CLOSED

Hi @simeonyetarian, @tnakasaki,

I've prepared pull request #12 to resolve this. It would be great if you could try out the change and provide any feedback.

from lorawan-library-for-pico.

I was facing the same issue with GCC 11.2.1 on Fedora Linux (x86).
The PR seems to solve it. With debug mode enabled, the correct DevEui and JoinEui are shown.

Joining the network is not yet working, but that is probably another issue ... ;-)

@ThomasLeister thanks for the feedback on PR #12! I've gone ahead an merged it.

Hi @simeonyetarian, @tnakasaki,

Sorry for the late response,
I've compiled on the Raspberry Pi 4, using the same setup as above. JoinEUI and DevEUI transmit correctly. Thank you so much for your solution!

I have been having the same issues, using US915 settings. I will post screenshots when I have time.

This issue only happens when compling on a Raspberry Pi 4. When I compile the uf2 on a Mac, the expected EUI values are transmitted.

simeonyetarian, which platform are you using to compile?

from lorawan-library-for-pico.

@tnakasaki Thanks for sharing that information! Indeed, I am compiling on a Raspberry Pi 4. Maybe I will try to compile on another device then

Update: I can confirm that compiling on a Windows machine instead of a Raspberry Pi works.
So this seems to be specific to the Raspberry Pi

Here are some screenshots that illustrate the aforementioned issue.
cmake and make were performed on a Raspberry Pi 4.

TTN gateway data. Note the incorrect values for both JoinEUI and DevEUI, 618A011029890110

Also, in config.h, if LORAWAN_DEVICE_EUI is set to NULL, a correct DevEUI will be transmitted. That is, the same value printed in the default_dev_eui example program. JoinEUI remains incorrect.

These are screenshots of cmake and make performed on a Mac. This compilation produced an executable that functioned correctly.

@simeonyetarian @tnakasaki Looks like it might be related to the version on Arm GCC used.

Based on the screenshots @tnakasaki provided in #8 (comment), they were using 7.3.1 or 8.3.0 on the Raspberry Pi, but using 9.2.1 on the Mac.

Any chance you could try to use a newer compiler version on the Raspberry Pi?

@simeonyetarian could you please provide the compiler versions you were using Raspberry Pi vs Windows? Thanks.
