// rf22_server.pde // -*- mode: C++ -*- // Example sketch showing how to create a simple messageing server // with the RH_RF22 class. RH_RF22 class does not provide for addressing or // reliability, so you should only use RH_RF22 if you do not need the higher // level messaging abilities. // It is designed to work with the other example rf22_client // Tested on Duemilanove, Uno with Sparkfun RFM22 wireless shield // Tested on Flymaple with sparkfun RFM22 wireless shield // Tested on ChiKit Uno32 with sparkfun RFM22 wireless shield #include #include // Singleton instance of the radio driver RH_RF22 rf22; void setup() { Serial.begin(9600); if (!rf22.init()) Serial.println("init failed"); // Defaults after init are 434.0MHz, 0.05MHz AFC pull-in, modulation FSK_Rb2_4Fd36 } void loop() { if (rf22.available()) { // Should be a message for us now uint8_t buf[RH_RF22_MAX_MESSAGE_LEN]; uint8_t len = sizeof(buf); if (rf22.recv(buf, &len)) { // RF22::printBuffer("request: ", buf, len); Serial.print("got request: "); Serial.println((char*)buf); // Serial.print("RSSI: "); // Serial.println(rf22.lastRssi(), DEC); // Send a reply uint8_t data[] = "And hello back to you"; rf22.send(data, sizeof(data)); rf22.waitPacketSent(); Serial.println("Sent a reply"); } else { Serial.println("recv failed"); } } }
