💬 Connecting the Radio

[mfalkvidd]

@DiverAlpha strange. You could try hard-coding the parent on the node, see MY_PARENT_NODE_IS_STATIC and MY_PARENT_NODE_ID on https://www.mysensors.org/download/sensor_api_20

[palande.vaibhav]

@DiverAlpha
I am no expert in this. But when I started using MySensors few months ago, I also had some problems. Not because there is a problem with MySensors but because I was doing the simplest of the mistakes and I needed to think simple and do simple things first.

What I would suggest is just try the simplest of the code first. This post is considering that you are using MySensors library 2.0.

This is what I did when I was trying out MySensors and I think you can try this too.

Firstly connect Arduino you are using properly to the radio with the proper connections using the instructions here. If you are using Arduino Mega, the SPI pins are different. Here is the link for Arduino Mega: https://forum.mysensors.org/topic/4940/arduino-mega-nrf-wiring/3. Make sure you have decoupling capacitors attached between the VCC and GND pins of both the radios.

After you make the connections upload the code for the gateway to one of the Arduinos. You can find the code in Arduino IDE, File > Examples > MySensors > GatewaySerial. Don't make any changes just upload the code.

Then what I did the first time is just run the following motion sensor code to the other Arduino. I have made a few changes to make things simpler for the node to find the gateway.

// Enable debug prints
#define MY_DEBUG

// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69

#define MY_NODE_ID 1

#define MY_PARENT_NODE_ID 0

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

//unsigned long SLEEP_TIME = 120000; // Sleep time between reports (in milliseconds)
#define DIGITAL_INPUT_SENSOR 3   // The digital input you attached your motion sensor.  (Only 2 and 3 generates interrupt!)
#define CHILD_ID 0   // Id of the sensor child

// Initialize motion message
MyMessage msg(CHILD_ID, V_TRIPPED);

void setup()  
{  
  pinMode(DIGITAL_INPUT_SENSOR, INPUT);      // sets the motion sensor digital pin as input
}

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

  // Register all sensors to gw (they will be created as child devices)
  present(CHILD_ID, S_MOTION);
}

void loop()     
{     
  // Read digital motion value
  boolean tripped = digitalRead(DIGITAL_INPUT_SENSOR) == HIGH; 
        
  Serial.println(tripped);
  send(msg.set(tripped?"1":"0"));  // Send tripped value to gw 

  // Sleep until interrupt comes in on motion sensor. Send update every two minute.
  //sleep(digitalPinToInterrupt(DIGITAL_INPUT_SENSOR), CHANGE, SLEEP_TIME);
}

Here, I have defined a NODE ID and defined the PARENT NODE ID for the node. Defining parent ID makes sure that the gateway that you have is the one, the node is supposed to connect to. I didn't even have motion sensor connected to the node here. This is just to make sure that first time you get everything working.

If this is done correctly the node and gateway should talk to each other and gateway should have the motion sensor registered.

Hope this helps.

[DiverAlpha]

Hy all,

Thanks for your help. Unfortunately it didn't solved the problem :-(.
I tried it with putting the NODE_ID's om static but that didn't help. MY_PARENT_NODE_IS_STATIC is totally not recognized in the Arduino IDE...

I tried just what @palande.vaibhav mentioned with the code he posted. The only adjustment is that I had to change the CE and CS pin on the sensot because I'm using a Adruino Micro. Further the code was just copy-paste but the same result in the serial communication as I posted earlier. (Except now the ID was 1 in stead of 105...)

[palande.vaibhav]

@DiverAlpha
I tried it on my setup. The node shows the output with BC (st=bc) when I only have the node connected in that is powered ON. But when I power ON my gateway in they start communicating and I get st=ok.

Here is the node without gateway connected:

Basically you need to have at least one node and a gateway working for MySensors to run properly.
Here is the thread I started when I had the same problem: https://forum.mysensors.org/topic/4941/problem-getting-the-code-to-run-with-mysensors-library-2-0/35

Read last few comments, you will get the idea of what I am saying. You can also try the fix for this suggested by ayo in the comment #35.

@mfalkvidd said:

@gvorster 868 is the default so you don't need to do anything. If you want to change it, add

#define MY_RFM69_FREQUENCY

Great, thanks!

I have a RFM69HCW and was getting a terrible connection from 5 meters through two thin walls.

After using:

#define IS_RFM69HW

The connection and range is incredible!
I live in an appartment 3rd floor, put a node in my mailbox which is 15 meters below and still got sensor data.
This did not work for me before using NRF24L01+

[pepson]

Hi
how long is real range on radio RFM69HW ? It is better than NRF24L01 ?

[hek]

@pepson said:

Yes, generally, lower frequency -> longer range (but also lower transmission speed).

[pepson]

But speed RFM69HW is too slow ? For use it to relay switch and some sensors... ? What is better to home automation ? RFM69HW or NRF24L01 ?

[gvorster]

@pepson said:

This post has some more info on this: Which is better: RFM69 or NRF24L01+

I want to use these radio's indoors and need to have a good connection through a couple of thin walls. My impression is that the RFM69 has at least better wall penetration. I'm using the RFM69HCW 868Mhz with only a 82mm wire connected to the ANT pin.

I tested the Mock sketch and enabled a few mock sensors. Throughout my appartment I have no problem having a good connection.

But, there are fake NRF24L01+ chips out there which might be the cause of my penetration connections errors.

I'm buying my RFM69 radio's from a reliable distributor in the Netherlands http://webshop.ideetron.nl/HopeRF

[pepson]

When uusing RFM69HW i must also use Capacitor as for NRF24L01 ?

[korttoma]

@pepson

I do not think that the RFM69HW is as sensitive as the NRF24L01 but adding a Capacitor will not hurt.
It also depends on how clean your power source is. If the power is clean you do not need to filter it using Capacitor.

Hi guys!

I'd like to ask you about a problem. When I use RFM69 radios on my nodes, they are working fine, but when I try to use the NRFs everything is falling apart and that's driving me crazy. I can't find the solution to use NRFs (I've got 20 of them). I tried everything, read the forum a hundred times, but can't find the solution. Poer sources are perfect, every NRF has it's own 3.3v source and after a few hours or a few days perfect working, the nodes disappear (not all and not in the same time). I'm using Domoticz as controller on a RPI 2. I saw the node's L13 led's blinking is much lighter after the node disappears. When it's working okay, the led is blinking on full.

Thank you for the suggestions, and have a nice day

[mfalkvidd]

@ZsoltZombori what does the serial debug output of the nodes say?

[palande.vaibhav]

@ZsoltZombori

I had a problem of the LED on pin 13 glowing dim after some time of system running fine when I had 2 sensors connected to the Arduino and sensors had their own separate 5V power supply. So, I had a 5V power supply separate from the Arduino's 5V and that was supplying current to those sensors.

I had the sensor's data pins connected to Arduino but I didn't have GND of power supply and Arduino connected. I solved the problem by connecting the GND of power supply to the GND of the Arduino.

See if that is the case with you.

Hope this helps.

[A Former User]

@mfalkvidd I put the node on serial for the night and everything works fine now. No errors occured, I'm still waiting.
@palande-vaibhav The GNDs are always connected in my circuits to prevent GND problems. Thanks for the tip.

[palande.vaibhav]

@ZsoltZombori
Exactly that was a problem with my system too. When I had it connected to the computer using the serial cable everything would just run fine but as soon as I removed the serial cable from computer and let it run on its own with the power supply connected with a DC jack, everything would just fall apart the LED's would go dim and that's when I discovered the problem of the ground but you already have all the grounds connected so I'm out of clues here.
I would suggest you to check the power supply connections again with a multimeter to make sure that everything is connected properly.

[A Former User]

@palande.vaibhav I double checked everything and the PCB is perfect. Still waiting for a failure, but it's working now. I'm wondering what was the problem for weeks with the NRFs. The RFMs are working like a charm. Anyway, thank you for the ideas :)
Edit: there were two fails in ~21hrs, I attach the debug code:

How i must change sketch Gateway and node to use radio RFM69HW ? In sketch i see only for simple RFM69 not RFM69HW.

[scalz]

for using RFM69HW, you just need to use the common rfm69 defines and add this

#define MY_IS_RFM69HW

[rmtucker]

@scalz
Do you add the rfm69hw def to the gateway sketch or to the myconfig.h?
