/* RadioLib SX123x Blocking Receive Example This example receives packets using SX1231 FSK radio module. Other modules from SX123x family can also be used. NOTE: SX123x modules offer the same features as RF69 and have the same interface. Please see RF69 examples for examples on AES, address filtering, interrupts and settings. Using blocking receive is not recommended, as it will lead to significant amount of timeouts, inefficient use of processor time and can some miss packets! Instead, interrupt receive is recommended. For default module settings, see the wiki page https://github.com/jgromes/RadioLib/wiki/Default-configuration#rf69sx1231 For full API reference, see the GitHub Pages https://jgromes.github.io/RadioLib/ */ // include the library #include // SX1231 has the following connections: // CS pin: 10 // DIO0 pin: 2 // RESET pin: 3 SX1231 radio = new Module(10, 2, 3); // or using RadioShield // https://github.com/jgromes/RadioShield //SX1231 radio = RadioShield.ModuleA; void setup() { Serial.begin(9600); // initialize SX1231 with default settings Serial.print(F("[SX1231] Initializing ...
