* When channel is active, first try receiving that packet
Afterwards we'll try transmitting again
* Remove setStandby in startSend
Already done in isChannelActive()
* Set LORA_DIO1 as RadioLib GPIO for SX127x
* LORA_DIO1 for Heltec v1, overlaps with GPS_TX
Set to RADIOLIB_NC for now
* If receive was not successful, startReceive doesn't trigger the interrupt
So we have to go back to transmitting anyway
