Node are not receiving messages from domoticz

[davy39]

@AWI Yes, I'm using examples "Serial Gateway" and "relayActuator". I've just changed gw.begin(incomingMessage, AUTO, true); to gw.begin(incomingMessage, 1, true); otherwise my node was not detected.

So, to answer to your first question, I guess I should read "Incoming change for sensor: ... , New status: ...." and state of pin 3 should change...

[AWI]

@davy39 That should pretty much bet true.. If you have "ack" set in Domoticz (default) then Domoticz will complain if the node did not receive the message.

[davy39]

@AWI I did get error messages (Error sending switch command, check device/hardware !) in the past and did played with the ack option in domoticz hardware menu.
In fact, I've just checked and ack was enabled without getting error messages... So I've disabled and re-enabled it, and I got error message back... How to know what happens in the gateway while receiving messages from Domoticz ?

[AWI]

@davy39 The best way to move forward is detach the gateway from Domoticz and try to send the message manualy to the node. You can use MYSController to do this and see what is going on. I doubt if Domoticz is the cause..

Great idea. I'll dig in that way.
Is there same kind of tool for linux ?
If not, maybe could I send some serial messages through arduino IDE's serial monitor ?
That probably means I'll need to learn a bit more about mysensor API...

[davy39]

With my node-id=1, my child-sensor-id would be 1 as well, I should send 1;1;1;0;2;1(without ack) or 1;1;1;1;2;1(with ack). Am I right ?
I've tried to send it through arduino IDE with a new line at the end, but the gateway is still not responding...
Am I missing something ?

Finally I got it !
In the stable version, baud-rate is at 115200, I changed it to 38400 in MyConfig.h and now it is working !
A question still need to be solved : why it is not working with the development libraries since 38400 is default baud-rate ?

[AWI]

@davy39 I'm not sure. All my nodes and gateways are running on 115200..

8 MHz Arduinos absolutely need to use lower baud rate than 115200. The baud rate is generated from the internal clock, and at 8 MHz 38400 bps is the highest baud rate close enough to the standard.

Good to know, indeed my setup is working now with stable libraries thanks to this helpful community.
I'll go back later to development libraries to see if I'm able to work with it as well.
