Sadly not. I ended up creating an serial gateway (arduino with NRF24L01 and a USB connector) and connected this to the Raspberry Pi, rather than connecting the NRF24L01 directly to the GPIO pins. This worked perfectly straight away.

Hi Alex,

I tested the Sanity check on the the Arduino sensor node, and status came back OK. However I could get this to work on the Raspberry Pi, seems like this function is not yet supported. At least I couldn't find any info on it using the "./configuration -h".

I don't have a AMS1117 available so I can test that.

I connected my Arduino Nano and NRF24L01+ to the Raspberry Pi via USB, that would really well. So I might just use this solution instead as I see little benefit of connecting the NRF24L01 directly to the GPIO pins on the Raspberry Pi.

Next step is to start building some battery powered sensors that I can use, and get MyController setup properly.

HI,

I've been doing some testing. I have two Gateways

1. Raspberry Pi 2 with a NRF24L01+ module connected to the GPIO pins
2. Arduino Nano with a NRF24L01+ module connected via a breadboard to my MacBook Pro

The sensor node is an Arduino Uno with a NRF24L01+ module. This sensor is sending out a higher number for each packet (eg. 1, 2, 3, 4)

Between the Raspberry Pi 2 gateway is have a lot of data loss as shown in earlier posts even with just 3 meters a part. However using the Arduino Nano as the gateway I can walk across the apartment with loosing anything (10+ meters away).

I've switched the NRF24L01 modules around and the result is the same.

I have now two possible reasons:

1. Something is wrong related to the Raspberry Pi 2 - The code, libraries, power to the NRF24L01 etc.
2. The Raspberry Pi is next to my ASUS RT-AC87U wireless router... maybe it is interfering (I don't think it is this, as I didn't have any packet loss with the Arduino Nano when I held it next to the router)

I therefore think it is related to point 1. The Raspberry Pi 2. But don't know what it could be...

Any ideas?

My sensors are located about 3 meters apart with nothing in between. To mitigate the packet loss I've increased by the Gateway to RF24_PA_HIGH and the Arduino to RF24_PA_MAX. I tested MAX on the Gateway aswell, but it didn't seem to handle this setting.

Note I've changed the code of the Node - it now sends a number per msg, and it increases by 1 for each message. This way I found it easier to track which msg that succeeded and which didn't.

First it looked ok, but the msg started to fail after some time (note: I have 3 seconds between each message now)

When I start the Gateway by using "sudo ./examples_linux/mysGateway -d" it starts fine, and connects with the Arduino which I restart at the same time as I type the code above in terminal to start the Gateway on the Raspberry Pi.

After the setup it seems like most of the first 13 messages go through successfully. Then the next 10 messages fail (atleast looks like it on the GW debug info). Then there is another good period from 23-40, but with a few lost. Then the rest fail, and the sensor also starts reporting the messages as failed. After this I have to restart the Sensor node to be able to regain communication.

Do anyone know what is wrong... ?

@alexsh1

You are 100 % correct

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.

@alexsh1

Again thanks for all the help, very much appreciated.

I started last evening putting together a few more NRF24L01 sensors such as the one on the Node. I will also setup a new extra Arduino Gateways, so I also can test communication between two Arduinos, before testing the same with the Raspberry Pi. Ill report back later tonight when I know the results.

looks like a power issue with the nrf24 module.

Ok,

I've tested with the Voltmeter and the NRF24L01 module do get a steady 3.26 V. Both the gateway module and the Arduino sensor node...

Im now building a few extra sensor nodes, so I can test without the Raspberry pi. Hopefully I can atleast get them talking based on Arduinos first. Before testing the Raspberry Pi.

@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. **

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 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

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?
