Here is the code that I am using:
#include <SPI.h>
#include <RH_RF69.h>
// Singleton instance of the radio driver
//RH_RF69 rf69;
//RH_RF69 rf69(15, 16); // For RF69 on PJRC breakout board with Teensy 3.1
//RH_RF69 rf69(4, 2); // For MoteinoMEGA https://lowpowerlab.com/shop/moteinomega
//RH_RF69 rf69(8, 7); // Adafruit Feather 32u4
RH_RF69 rf69(D6, D7);
void setup()
{
Serial.begin(9600);
while (!Serial)
;
if (!rf69.init())
Serial.println("init failed");
// Defaults after init are 434.0MHz, modulation GFSK_Rb250Fd250, +13dbM (for low power module)
// No encryption
if (!rf69.setFrequency(915.0))
Serial.println("setFrequency failed");
// If you are using a high power RF69 eg RFM69HW, you *must* set a Tx power with the
// ishighpowermodule flag set like this:
rf69.setTxPower(14, true);
// The encryption key has to be the same as the one in the server
uint8_t key[] = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08,
0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08};
rf69.setEncryptionKey(key);
}
void loop()
{
Serial.println("Sending to rf69_server");
// Send a message to rf69_server
uint8_t data[] = "Hello World!";
rf69.send(data, sizeof(data));
rf69.waitPacketSent();
// Now wait for a reply
uint8_t buf[RH_RF69_MAX_MESSAGE_LEN];
uint8_t len = sizeof(buf);
if (rf69.waitAvailableTimeout(500))
{
// Should be a reply message for us now
if (rf69.recv(buf, &len))
{
Serial.print("got reply: ");
Serial.println((char*)buf);
}
else
{
Serial.println("recv failed");
}
}
else
{
Serial.println("No reply, is rf69_server running?");
}
delay(400);
}
