Hi!

I have a working 433MHz gateway over WiFi, but the WiFi bands are too crowded around my home, so
I wanted to build a serial gateway with USB connection.

I can plug it directly in my home automation server.

Here are the first renderings of the PCB and case.

As I did the PCB layout last weekend, I have yet some refactoring to do...

@electrik Good point! I copied these defines from some post in this forum, but it matches the pinout from Adafruit
You got me thinking that maybe there is something wrong in the Adafruit documentation about the Feather M0 built-in RFM69... The image on top says pin 7 for the RFM interrupt ... :confused: I tried pin 7, no dice...

I have a Feather M0 Express where I hooked up a RFM69HCW breakout, and it works! Naturally I had to modify the defines for the pins.

Here is the code for the Feather M0 Express:

#define MY_DEBUG
#define MY_BAUD_RATE 9600
#define MY_DEBUG_VERBOSE_TRANSPORT_HAL

#define MY_RADIO_RFM69
#define MY_RFM69_NEW_DRIVER
#define MY_RFM69_FREQUENCY (RFM69_433MHZ)
#define MY_IS_RFM69HW

#define MY_RFM69_IRQ_PIN (12)
#define MY_RFM69_IRQ_NUM digitalPinToInterrupt(MY_RFM69_IRQ_PIN)
#define MY_RFM69_RST_PIN (5)
#define MY_RFM69_CS_PIN 10

#define MY_SIGNAL_REPORT_ENABLED

#define MY_NODE_ID 4

#include "MySensors.h"


#define VBATPIN A7
#define CHILD_ID_VOLTAGE  0

MyMessage msgVoltage( CHILD_ID_VOLTAGE,  V_VOLTAGE );

// Sleep time between sensor updates (in milliseconds)

void setup() {
  // put your setup code here, to run once:
  Serial.print("Setup... ");
}

void presentation() {
  // Send the sketch version information to the gateway and Controller
  sendSketchInfo("My M0 Express Sensor", "1.0");

  // Present sensors as children to gateway
  present(CHILD_ID_VOLTAGE, S_MULTIMETER, "Voltage");
}

void loop() {
  float measuredvbat = analogRead(VBATPIN);
  measuredvbat *= 2;    // we divided by 2, so multiply back
  measuredvbat *= 3.3;  // Multiply by 3.3V, our reference voltage
  measuredvbat /= 1024; // convert to voltage
  send(msgVoltage.set(measuredvbat, 2));

  #ifdef MY_DEBUG
    Serial.print("VBat: " ); Serial.println(measuredvbat);
  #endif

  wait(30000); 
}

And this is the debug output:

Hello everybody out there!

I can't say how I feel right now... my Feather M0 with built-in RFM69 has finally connected to the gateway !!!
:joy: :laughing: :open_mouth:

I commented 3 lines in my non-working code and uploaded it again ... And I don't know why it works now...
but i suspect the line with the define of the IRQ_NUM :face_with_rolling_eyes:

#define MY_DEBUG
#define MY_BAUD_RATE 9600
//#define MY_DEBUG_VERBOSE_TRANSPORT_HAL

#define MY_RADIO_RFM69
#define MY_RFM69_NEW_DRIVER
#define MY_RFM69_FREQUENCY (RFM69_433MHZ)
#define MY_IS_RFM69HW

#define MY_RFM69_CS_PIN 8                          // SPI CS PIN
#define MY_RFM69_IRQ_PIN 3                         // IRQ PIN
//#define MY_RFM69_IRQ_NUM 3                         // IRQ PIN NUM (for M0 it is the same as IRQ PIN. Will be obsolete in upcoming MySensors.h) 

#define MY_RFM69_RST_PIN 4

#define MY_SIGNAL_REPORT_ENABLED
//#define MY_TRANSPORT_WAIT_READY_MS 15000 

#define MY_NODE_ID 14

#include <SPI.h> 
#include "MySensors.h"


#define VBATPIN A7
#define CHILD_ID_VOLTAGE  0
