Ok, I have figured this out. When sending the value via the serial port there must be a delay between the characters (3ms). Therefore I do something like this (schematically), which works:

foreach (char c in "255;255;3;0;4;1")
{
serialPort1.Write(c.ToString());
Thread.Sleep(3);
}

I am trying to send the values, but nothing happens. I am sending "255;255;3;0;4;1\n" over serial port (USB) to the serial gateway, but this does not seem to be processed. Either it is not sent to the sensor at all, or the sensor does not react. I am trying to send this from either Serial Monitor in the Arduino Studio or from my C# code, console app. The serial port works and reads the values properly, however sending this sequence seems to be an issue.

Hi, I have read the whole API documentation but still do not seem to find the way to configure the node ID. I have found this topic http://forum.mysensors.org/topic/350/problems-getting-sensorid/11 but sending the command "255;255;3;0;4;1" to the node did not help though. I would appreciate any hints on this topic. Thank you!

Thank you for pointing me to this direction. Happy New Year!

Thank you for the response, however it does not make sense to me. How would it be possible for a controller to assign the ID? There must be some set of commands (API) on the node that are used by the controllers to assign the node ID's, right? I basically want to write a code that will act as a controller in terms of assigning the ID's to the nodes. Is this possible?
Thanks!

I see, great, thank you! Is there a way how to assign the ID of the node from outside, without a controller? Let's say, there will be a number of nodes, sensors being turned on or off and the ID's should be assigned using the serial gateway from the connected PC. I guess this is what the controllers must be doing, I just want to control it myself.
Thank you

Hi all,

I am trying to setup a simple example. I use 2 Pro Mini with NRF24L01 to create simple binary sensor and serial gateway. I read the output from the serial gateway but the values read are not changing when the switch is toggled.
The sensor uses this simple code: http://www.mysensors.org/build/binary#binaryswitchsensor-example
And gateway is this: http://www.mysensors.org/build/serial_gateway No modifications to any of them. I do not use any controller, I was to de-serailize the output from the serial port myself on a PC for now.

I have the output from the serial monitor which is following for the sensor and serial gateway:

door sensor:
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
sensor started, id=255, parent=0, distance=1
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:

serial gateway:

0;0;3;0;9;read: 255-255-0 s=255,c=3,t=3,pt=0,l=0,sg=0:

0;0;3;0;9;read: 255-255-0 s=255,c=3,t=3,pt=0,l=0,sg=0:
255;255;3;0;3;
0;0;3;0;9;read: 255-255-0 s=255,c=3,t=3,pt=0,l=0,sg=0:
255;255;3;0;3;

I have searched this forum and is seems the issue might be the sensor trying to get the ID (as per the "req id" output). Any idea how to fix this?

Thanks!

Many thanks for sharing, much appreciated!

Hi barduino,
Thank you for your response! Yes, an example would be very much appreciated. Does it mean you have this simple serial gateway: http://www.mysensors.org/build/serial_gateway? and run the NodeJS program on the computer it is connected to? What do you use to read from serial gateway and send to REST API, RPi?

Thanks for your swift advice! Does it mean you hacked the GatewayUtil.h of the EthernetGateway code from GitHub to send the data to REST API?
