* EBYTE LoRa E220
|
|
* Stay in sleep mode and wait a wake up WOR message
|
|
*
|
|
* You must configure the address with 0 2 23 (FIXED RECEIVER configuration)
|
|
* and pay attention that WOR period must be the same of sender
|
|
*
|
|
* You must uncommend the correct constructor and set the correct AUX_PIN define.
