Hi,

I'm stuck trying to setup my Raspberry Pi 2 with NRF24L01 to the GPIO pins as a Gateway and as a controller (MyController.org). Im trying to use MySensors 2.0 library. I will gladly pay a bit if someone can help with 1-to-1 via Skype or similar to get this working. As Im close to giving up on my own...

Any help is very much appreciated.

Configuration of the gateway on the Raspberry Pi 2

pi@raspberrypi:~/MySensors $ ./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway --my-radio=nrf24 --my-rf24-channel=0
[SECTION] Detecting target machine.
[OK] machine detected: SoC=BCM2836, Type=Rpi2, CPU=armv7l, REV=a01041.
[OK] init system detected: systemd
[SECTION] Saving configuration.
[SECTION] Cleaning previous builds.
[OK] Finished.

Make command on the Raspberry Pi 2 via Terminal on my Mac.

I then ran the mysGateway

pi@raspberrypi:~/MySensors $ sudo ./examples_linux/mysGateway -d

Then over to the Arduino Uno that is also connect with an NRF24L01

The sketch I'm running on the Arduino

However with this sketch I'm recieving an error that I can read on the Serial Monitor on my Mac (output from the Arduino sensor node)

I don't understand what is wrong. I do believe all the wires are correct, so I believe it is related to the Arduino sketch, or more likely the gateway setup on the Raspberry Pi.

I hope someone can help. I'll gladly pay someone to give me some 1-to-1 support over Skype or similar.

@alexsh1 said:

FPAR: FAIL = Find Parent Fail. The sensor is looking for a parent, but cannot find it. There can be several reasons for this:

1. Try to add larger capacitors to both radios on GW and the sensor.
2. Please use a default sketch on the sensor, no signing etc.
3. Double check if the channel is the same. You are using channel 0 on RPi. What about the sensor? Did you change it from a default 76?
4. Did you upload both sketches using MySensors 2.0?
5. Please check the power feed on both GW and the sensor.

Hi thanks for the support. Hope you are able to elaborate a bit on your points.

1. Try to add larger capacitors to both radios on GW and the sensor.
   I'm using a 4.7 uF Capacitator on both the NRF24L01 on the Raspberry Pi, and on the NRF24L01 on the Arduino. Do you think I still need a bigger capacitor?

2. ** Please use a default sketch on the sensor, no signing etc.**

Can you share a default sketch to use?

I have tried the below sketch from this page https://www.mysensors.org/download/sensor_api_20#sensor-nodes
But the sketch do not compile due to non defined NODE_ID. I tried to updated the code by changing NODE_ID to MY_NODE_ID and added a line to #DEFINE MY_NODE_ID 1

Is this correct? See the updated code that I've used below

#define MY_RADIO_NRF24
#define MY_DEBUG

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

#define MY_NODE_ID 1
#define MY_PARENT_NODE_ID 0
#define MY_PARENT_NODE_IS_STATIC

MyMessage msg(MY_NODE_ID, V_TRIPPED);

void presentation()
{
    present(MY_NODE_ID, S_DOOR);
}

void loop()
{

}

With this code I still get an error (this is the Arduino Uno sensor node)

4. Did you upload both sketches using MySensors 2.0?
   Not sure how you upload the sketch to the RPI 2 using MySenors 2.0. However I have atleast tried to follow this tutorial. https://www.mysensors.org/build/raspberry

The actual steps I did are repeated below.

git clone https://github.com/mysensors/MySensors.git
cd MySensors

./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway --my-radio=nrf24

sudo make all 

sudo make install

sudo systemctl enable mysgateway.service

sudo ./examples_linux/mysGateway -d

5. Please check the power feed on both GW and the sensor.
   How do you do this?

@alexsh1

Thanks for all the tips.

I've now installed a new 100 uF (16V) Capacitor in parallell with the current 4.7 uF (50V) capacitor on both the units, I also double checked the writing just to be sure. It all looks good. See images below.

**After adding the capacitor, I uninstalled and cleaned the setting on the Raspberry Pi. **

MySensors gateway has been installed, to add to the boot run:
  sudo systemctl enable mysgateway.service
To start the gateway run:
  sudo systemctl start mysgateway.service

start the gateway

pi@raspberrypi:~/MySensors $ sudo systemctl start mysgateway.service

Start the debug on the gateway:

Now, the gateway on the Raspberry Pi 2 seem ok and up and running. Moving over to the sensor node, the Arduino Uno with NRF24L01+.

Uploaded and ran the Clear_EPROM sketch

/*
*
* This sketch clears radioId, relayId and routing info in EEPROM 
*
*/

#include <SPI.h>
#include <EEPROM.h>  

void setup()  
{ 
  for (int i=0;i<512;i++) {
    EEPROM.write(i, 0xff);
  }
  Serial.println("EEPROM cleared");
}

void loop()      
{ 
  // Nothing to do here...
} 

After this I uploaded your recommended default sketch. However I added "#define MY_RF24_CHANNEL 76"

// Enable debug prints to serial monitor
#define MY_DEBUG 

// Enable and select radio type attached
#define MY_NODE_ID 1
#define MY_PARENT_NODE_ID 0
#define MY_PARENT_NODE_IS_STATIC
#define MY_RADIO_NRF24
#define MY_RF24_CHANNEL 76

#include <MySensors.h>  

#define CHILD_ID_LIGHT 0
#define LIGHT_SENSOR_ANALOG_PIN 0

unsigned long SLEEP_TIME = 30000; // Sleep time between reads (in milliseconds)

MyMessage msg(CHILD_ID_LIGHT, V_LIGHT_LEVEL);
int lastLightLevel;


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

  // Register all sensors to gateway (they will be created as child devices)
  present(CHILD_ID_LIGHT, S_LIGHT_LEVEL);
}

void loop()      
{     
  int16_t lightLevel = (1023-analogRead(LIGHT_SENSOR_ANALOG_PIN))/10.23; 
  Serial.println(lightLevel);
  if (lightLevel != lastLightLevel) {
      send(msg.set(lightLevel));
      lastLightLevel = lightLevel;
  }
  sleep(SLEEP_TIME);
}

The result, enoyingly is the same it seems based on the output from the Serial Monitor from the Arduino Uno.

Frustrating... Can it be other modules, libraries than what I've not installed on the Raspberry Pi that is the reason for the error?

@alexsh1

You are 100 % correct :+1: :)

I changed the NRF24L01 module with the antenna, with a standard NRF24L01+ module. And it works like a charm.

Here are the Serial Monitor code from the Arduino (Sensor node). I don't currently understand what all the code says, but it seems like they are communicating.
