Enhancement: add scheme for run-time configuration of US sub-bands #2

Closed danak6jq closed 2 years ago

danak6jq commented 2 years ago

The ST port of Semtech reference port offers a HYBRID_ENABLED scheme to select a subset of US915 channels. Production motes really require the ability to configure the channel map in the field, need an API for this

After looking into this, I'm not so sure sub-band support is that critical for OTAA devices. Adding a couple of lines of code to the join callback in lora_app.c will re-try until a GW is found; the GW will then send down the channel mask to use:

`static void OnJoinRequest(LmHandlerJoinParams_t joinParams) { / USER CODE BEGIN OnJoinRequest_1 */

if (joinParams->Status == LORAMAC_HANDLER_ERROR) {
    LmHandlerJoin(ActivationType);
}

/ USER CODE END OnJoinRequest_1 / }`
