semtech-loramac not joining with DR above 2 after update #10103
Description
Description
While trying to run the lorawan example I found that any join attempt after setting the Data Rate to a number above 2 fails. This seems to be related to the recently merged PR that updates the semtech-loramac implementation #8864. I tested the lorawan example with the previous version (checked out a commit before the PR was merged) and it works.
Steps to reproduce the issue
- Enable debug on
semtech_loramac.c. - Run the lorawan example:
BOARD=b-l072z-lrwan1 make clean flash term -C examples/lorawan/
You can also try to modify the Data Rate, and check that it works:
semtech_loramac_set_dr(&loramac, LORAMAC_DR_2);Expected results
Get something like

Further tests
I also tried running the tests/pkg_semtech-loramac application but it does not join when the Data Rate is above 2:
> loramac set dr 5
INFO # loramac set dr 5
> loramac get dr
INFO # loramac get dr
INFO # DATARATE: 5
> loramac join otaa
INFO # loramac join otaa
INFO # Join procedure failed!
> loramac set dr 0
INFO # loramac set dr 0
> loramac join otaa
INFO # loramac join otaa
INFO # Join procedure succeeded!
