[Help!] Adafruit Feather M0 with built-in RFM69HCW can't find parent / GW

[DeepCore]

Hello!
I am new to MySensors which I did find through Home Assistant.

I have successfully built an ESP8266 gateway with an Adafruit RFM69HCW breakout module. I also got a node running with an Arduino Pro Micro and the RFM69HCW breakout. Having a Feather 328p, I also got it working as node with the aforementioned breakout module. Last try with a Feather M0 Express and the breakout module was also successful.

But I am totally incapable of getting an Adafruit Feather M0 with built-in RFM69HCW to connect to my gateway... Why?

I use the MySensors library 2.4.0-alpha from GitHub. These are the defines I have for the Feather M0:

#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_RST_PIN (4)
#define MY_RFM69_IRQ_PIN (3)
#define MY_RFM69_IRQ_NUM (3)
#define MY_RFM69_CS_PIN (8)

This is the debug output in a terminal :

@DeepCore said in [Help!] Adafruit Feather M0 with built-in RFM69HCW can't find parent / GW:

#define MY_RFM69_IRQ_PIN (3)
#define MY_RFM69_IRQ_NUM (3)

Wild guess... These are not the same normally. Pin 3 is probably interrupt 2, you can find the right one by using

#define MY_RFM69_IRQ_NUM digitalPinToInterrupt(MY_RFM69_IRQ_PIN)

[DeepCore]

@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 ... 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:

7 should be right. Did you also change the irq number when you tried pin 7?

[DeepCore]

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 !!!

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

#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_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)

[DeepCore]

I was chasing a red herring !
What I have written in my posts above is simply non-sense, excuse me !

I have 2 Feather M0 with the integrated radio module, and only one of the Feathers connects to the gateway.

When I try the two Feathers with the simple TX/RX examples from the RadioHead Library modified by Adafruit, they work... And I switched the role of each module ... so they can transmit and receive.

But one Feather refuses to get a connection to the gateway ... I don't know why

[mfalkvidd]

@DeepCore do you remember if both modules got similar rssi when you tested the Adafruit rx/tx sketch?

[DeepCore]

@mfalkvidd yes, I got the same RSSI value, regardless which one was the receiver. Were you thinking that maybe one radio module was on the wrong frequency range ?

[mfalkvidd]

@DeepCore not wrong frequency no. But it looks like the feather doesn’t come with the antenna pre-soldered. Since the devices should be identical otherwise, the antenna could be what differs. But if it was, the rssi would probably have been different as well.
