Q:
Do you have to do anything with the gpio pins to set up the module as a receiver? Is the switch on the module controlled via the SX1276? Or a GPIO pin? -
A:
There is antenna switch to switch the module to TX/RX mode. And pin 20 of SX1276 is used to control the antenna switch. The pin named RXTX/RFMOD in the datasheet of SX1276. This pin is not led out on the module.
