Hi everyone, at first I want to say sorry because I use another library to develop my network but I create a topic here.

I would like to know that whether anyone using Mysensors library got the problem with Interference when using nRF24L01 ?

It means the network will get stuck, the node can't join the network and the gateway can't recognise the node (for example: gateway can't send/receive message to/from node) for some minutes (sometimes 30 minutes) and it will run again after that. I used "scanner.ino" (a sample code from RF24 library) to test interference and I found that there was interference on the channel that I was using.

I'm trying to find a solution for this issue. Recently, I change the channel manually in the code, but it's too inconvenient, I have to reupload the code each time I change the channel.

Does anyone have experience with this issue ?

Thank you for reading.

@mfalkvidd I just want to use AirQualitySensor to send a random number to GatewaySerial (because I don't have an Air Sensor so I send a random number). That's exactly what I want to do now.

@mfalkvidd I've read this link https://www.mysensors.org/download/sensor_api_20#message-constructor too, but I'm so confused what I have to do to change "255 - 255 - 255 - 255" to "2 - 2 - 0 - 0", I don't know what to do with the code in the link. Where do I have to change the code to configure the message frame ?

Thank you martinhjelmare.
I have read the page https://www.mysensors.org/download/serial_api_20 and I know the format of the message frame but I don't know how to change these things in the sketch . I spent a week trading code in the library and got nothing @@
Maybe I'm so noob to fine the way to build just an example Could you give me a link that shows how to change the message frame ?

Hi everyone, I'm using UNO to build a Serial Gateway and Pro mini to build a sensor node. I use GatewaySerial and AirQualitySensor in Mysensors' example to test the code. I want to send continuously a random number from the AirQualitySensor to GatewaySerial. This is what appearing on my Serial Monitor:
0;255;3;0;9;Starting gateway (RNNGA-, 2.0.0)
0;255;3;0;9;TSM:INIT
0;255;3;0;9;TSM:RADIO:OK

Could you tell me how to change the structure of this line "0-0-255-255 s=255,c=3,t=8,pt=1,l=1,sg=0,ft=0,st=bc:0" like in this example:

Thank you very much.
