2. Verification result

Please go through the README.md for how to setup Hardware & use LoraWAN extension.

GA release performs verification by the unit test provided in projects/lorawan_extension/test folder, projects/lorawan_extension/components/lbm_applications/4_porting_efr32/main_examples/main_porting_tests example.

Each example will have README.md file with instructions on how to run & the test results of each test.

3. Known issues in current release

LCTT Certification examples issues:

• Switch class command is unable to change class of end device from server in certification mode (still able to change class in normal operation).
• Current Chirpstack network server does not support tools to validate result of regional band duty-cycle enforcement command.
