/* RadioLib CC1101 Blocking Transmit Example This example transmits packets using CC1101 FSK radio module. Each packet contains up to 64 bytes of data, in the form of: - Arduino String - null-terminated char array (C-string) - arbitrary binary data (byte array) Using blocking transmit is not recommended, as it will lead to inefficient use of processor time! Instead, interrupt transmit 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 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 ...
