* KiteLib SX127x Transmit Example
|
|
*
|
|
* This example transmits packets using SX1278 LoRa radio module.
|
|
* Each packet contains up to 256 bytes of data, in the form of:
|
|
* - Arduino String
|
|
* - null-terminated char array (C-string)
|
|
* - arbitrary binary data (byte array)
|
|
*
|
|
* Other modules from SX127x family can also be used.
|
|
* SX1272 lora = Kite.ModuleA;
|
|
* SX1273 lora = Kite.ModuleA;
|
|
* SX1276 lora = Kite.ModuleA;
|
|
* SX1277 lora = Kite.ModuleA;
|
|
* SX1279 lora = Kite.ModuleA;
