/* RadioLib CC1101 Blocking Receive Example This example receives packets using CC1101 FSK radio module. To successfully receive data, the following settings have to be the same on both transmitter and receiver: - carrier frequency - bit rate - frequency deviation - sync word 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#cc1101 For full API reference, see the GitHub Pages https://jgromes.github.io/RadioLib/ */ // include the library #include // CC1101 has the following connections: // CS pin: 10 // GDO0 pin: 2 // RST pin: unused // GDO2 pin: 3 (optional) CC1101 radio = new Module(10, 2, RADIOLIB_NC, 3); // or detect the pinout automatically using RadioBoards // https://github.com/radiolib-org/RadioBoards /* #define RADIO_BOARD_AUTO #include Radio radio = new RadioModule(); */ void setup() { Serial.begin(9600); // initialize CC1101 with default settings Serial.print(F("[CC1101] Initializing ...
