I am trying to receive the radio packets on my adafruit mo LoRa transmitter , sent from microchip LoRa development board, but it seems like it is not receiving any radio packets, any suggestions? i modified the init() settings too,
// Feather9x_RX
// -- mode: C++ --
// Example sketch showing how to create a simple messaging client (receiver)
// with the RH_RF95 class. RH_RF95 class does not provide for addressing or
// reliability, so you should only use RH_RF95 if you do not need the higher
// level messaging abilities.
// It is designed to work with the other example Feather9x_TX
LoRa Rx Code:
#include <SPI.h>
#include <RH_RF95.h>
/* for feather m0 RFM9x*/
#define RFM95_CS 8
#define RFM95_RST 4
#define RFM95_INT 3
// Change to 434.0 or other frequency, must match RX's freq!
#define RF95_FREQ 868.1
// Singleton instance of the radio driver
RH_RF95 rf95(RFM95_CS, RFM95_INT);
// Blinky on receipt
#define LED 13
void setup()
{
pinMode(LED, OUTPUT);
pinMode(RFM95_RST, OUTPUT);
digitalWrite(RFM95_RST, HIGH);
Serial.begin(57600);
while (!Serial) {
delay(1);
}
delay(100);
Serial.println("Feather LoRa RX Test!");
// manual reset
digitalWrite(RFM95_RST, LOW);
delay(10);
digitalWrite(RFM95_RST, HIGH);
delay(10);
while (!rf95.init()) {
Serial.println("LoRa radio init failed");
while (1);
}
Serial.println("LoRa radio init OK!");
// Defaults after init are 434.0MHz, modulation GFSK_Rb250Fd250, +13dbM
if (!rf95.setFrequency(RF95_FREQ)) {
Serial.println("setFrequency failed");
while (1);
}
Serial.print("Set Freq to: "); Serial.println(RF95_FREQ);
// Defaults after init are 434.0MHz, 13dBm, Bw = 125 kHz, Cr = 4/5, Sf = 128chips/symbol, CRC on
// The default transmitter power is 13dBm, using PA_BOOST.
// If you are using RFM95/96/97/98 modules which uses the PA_BOOST transmitter pin, then
// you can set transmitter powers from 5 to 23 dBm:
rf95.setTxPower(13, true);
}
void loop()
{
if (rf95.available())
{
// Should be a message for us now
uint8_t buf[RH_RF95_MAX_MESSAGE_LEN];
uint8_t len = sizeof(buf);
if (rf95.recv(buf, &len))
{
digitalWrite(LED, HIGH);
RH_RF95::printBuffer("Received: ", buf, len);
Serial.print("Got: ");
Serial.println((char*)buf);
Serial.print("RSSI: ");
Serial.println(rf95.lastRssi(), DEC);
// // Send a reply
// uint8_t data[] = "And hello back to you";
// rf95.send(data, sizeof(data));
// rf95.waitPacketSent();
// Serial.println("Sent a reply");
// digitalWrite(LED, LOW);
}
else
{
Serial.println("Receive failed");
}
}
}
