* EBYTE LoRa E220
|
|
* send a structured message to the device that have ADDH ADDL CHAN -> 0 DESTINATION_ADDL 23
|
|
*
|
|
* write the int humidity value on serial (or reset device that send default message)
|
|
*
|
|
* You must configure 2 device: one as SENDER (with FIXED SENDER config) and uncomment the relative
|
|
* define with the correct DESTINATION_ADDL, and one as RECEIVER (with FIXED RECEIVER config)
|
|
* and uncomment the relative define with the correct DESTINATION_ADDL.
|
|
*
|
|
* Write a string on serial monitor or reset to resend default value.
|
|
*
|
|
* Pay attention e220 support RSSI, if you want use that functionality you must enable RSSI on configuration
|
|
* configuration.TRANSMISSION_MODE.enableRSSI = RSSI_ENABLED;
|
|
*
|
|
* and uncomment #define ENABLE_RSSI true in this sketch
|
|
*
|
|
* You must uncommend the correct constructor and set the correct AUX_PIN define.
