ok thank you

can someone can just answer this question :
"gw.request(CHILD_ID_SONAR_MIN_RANGE, V_DISTANCE);", response is provided by the controller ?

thank you

Hi,

I would like to build a customizable node (customizable by the controller) wich can detect presence for a certain distance.
The node comportement is good...

• Is it good practice to do a sketch like this ?
• "gw.request(CHILD_ID_SONAR_MIN_RANGE, V_DISTANCE);", response is provided by the controller ?
• Can i store my minimum range distance in EEPROM ? or is it better to do a "gw.request" ?

I used a mini pro whith FTDI :

It wasn't working the serial gateway don't send data.

I test with a nano and all is ok now ...

And on my relay sensor :

Terminal ready
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=ok:
read: 0-0-255 s=255,c=3,t=4,pt=0,l=1,sg=0:1

send: 1-1-0-0 s=1,c=0,t=3,pt=0,l=0,sg=0,st=ok:

i try with the option without success.

I also try to reset EEPROM & assigning Node ID with "MYScontroller" :

On my node :

Terminal ready
req id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,sg=0,st=fail:
repeater 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:

I think my gateway don't really send message ...
Any idea why ?

yep it's the french version of arduino IDE

I also try to put my gateway on a widows machine and on arduino ide :

I send : 1;1;1;0;2;1

But on my node :

bash>  picocom /dev/ttyUSB1 -b 115200 -r -l --omap lfcrlf --imap lfcrlf --emap lfcrlf
picocom v1.7

port is        : /dev/ttyUSB1
flowcontrol    : none
baudrate is    : 115200
parity is      : none
databits are   : 8
escape is      : C-a
local echo is  : no
noinit is      : no
noreset is     : yes
nolock is      : yes
send_cmd is    : sz -vv
receive_cmd is : rz -vv
imap is        : lfcrlf,
omap is        : lfcrlf,
emap is        : lfcrlf,

Terminal ready
send: 1-1-0-0 s=255,c=0,t=18,pt=0,l=3,sg=0,st=ok:1.5
send: 1-1-0-0 s=255,c=3,t=6,pt=1,l=1,sg=0,st=ok:0

send: 1-1-0-0 s=1,c=0,t=3,pt=0,l=0,sg=0,st=ok:

I also tried using node.js ...

I check if i receive serial data on my gateway using :

bash> picocom /dev/ttyUSB1 -b 115200 -r -l --omap lfcrlf --imap lfcrlf --emap lfcrlf
Terminal ready
send: 1-1-0-0 s=255,c=0,t=18,pt=0,l=3,sg=0,st=ok:1.5
send: 1-1-0-0 s=255,c=3,t=6,pt=1,l=1,sg=0,st=ok:0
repeater started, id=1, parent=0, distance=1
send: 1-1-0-0 s=255,c=3,t=11,pt=0,l=5,sg=0,st=ok:Relay
send: 1-1-0-0 s=255,c=3,t=12,pt=0,l=3,sg=0,st=ok:1.0
send: 1-1-0-0 s=1,c=0,t=3,pt=0,l=0,sg=0,st=ok:

Here is my node.js script :

const gwType = 'Serial';
//const gwPort = 'COM4';
const gwPort = '/dev/ttyUSB0';
const gwBaud = 115200;

//var SerialPort = require('/home/bxl/node-v0.12.0-linux-x64/lib/node_modules/serialport');
var serialport = require('/home/bxl/node-v0.12.0-linux-x64/lib/node_modules/serialport');
var SerialPort = serialport.SerialPort;


gw = new SerialPort(gwPort,
        { baudrate: gwBaud
          ,parser: serialport.parsers.readline("\n")
});

            gw.on('open', function() {
                        console.log('connected to serial gateway at ' + gwPort);
                        gw.write('1;1;1;0;2;1');
                        console.log('Write done.');
                }).on('end', function() {
                        console.log('disconnected from gateway');
                }).on('error', function() {
                        console.log('connection error - trying to reconnect');
                        gw.open();
                });

but nothing move on my serial gateway

tried :

echo "1;1;1;0;2;1" >> /dev/ttyUSB0

without success

i can't update my relay trhough serial ...

My gateway is on : /dev/ttyUSB0
My relay sensor is on : /dev/ttyUSB1

both sketch are from mysensors sample code except i force sensor node to 1 for my sensor relay.

This is what i read from gateway serial :

send: 1-1-0-0 s=1,c=0,t=3,pt=0,l=0,sg=0,st=ok:

What can i do to update my relay status ?
i try :
bash> echo "1;1;1;0;1;\n" >> /dev/ttyUSB0

tx led blink but i have nothing in my serial
