sx127x Channel Activity Detection

Hi,

I’m trying to detect LoRa channel activity using the sx127x driver. To do this, I call sx127x_start_cad(&mysx127x) and when the NETDEV_EVENT_CAD_DONE event comes in (which it does), I check mysx127x._internal.is_last_cad_success

However, is_last_cad_success is never true, even when there’s other LoRa activity on the channel. Am I missing something?

Thanks,

Nick
