Feather 32U4 Serial Failure rf95.init()

Post by jgrimble »

Hi,

I purchased a "Adafruit Feather 32u4 RFM69HCW Packet Radio - 868 or 915 MHz - RadioFruit",...
https://www.adafruit.com/product/3076

....I successfully added the RadioHead library, and I uploaded the example code to to my feather device. When I open the serial 115200 window, the code fails on the "rf95.init()" portion of the code. Here is the first few lines of code....

//*****************************Arduino Code Below*********************************
#include <SPI.h>
#include <RH_RF95.h>

// for feather32u4
#define RFM95_CS 8
#define RFM95_RST 4
#define RFM95_INT 7

// Change to 434.0 or other frequency, must match RX's freq!
#define RF95_FREQ 915.0

// Singleton instance of the radio driver
RH_RF95 rf95(RFM95_CS, RFM95_INT);

void setup()
{
pinMode(RFM95_RST, OUTPUT);
digitalWrite(RFM95_RST, HIGH);

Serial.begin(115200);
while (!Serial) {
delay(1);
}

delay(100);

Serial.println("Feather LoRa TX Test!");

// manual reset
digitalWrite(RFM95_RST, LOW);
delay(1000);
digitalWrite(RFM95_RST, HIGH);
delay(1000);

while (!rf95.init()) {
Serial.println("LoRa radio init failed");
while (1);
}
Serial.println("LoRa radio init OK!");
/*************************Arduino Code Above***************************

...The output from this code in the serial prompt is ...."LoRa radio init failed"

If anyone can help me with this issue I would be very grateful!!!

Thank you in advanced,
John

The board you have linked is the RFM69HCW and it is not compatible with the RF95 libraries. Use the RadioHead RFM69 examples instead.
