Hi there,
For some reasons I have to send a reboot request to one of my node (with id:1).

When I send this message from my controller:
1;255;3;0;13;
I got this log from the GW :
0;0;3;0;9;send: 0-0-1-1 s=255,c=3,t=13,pt=0,l=0,st=fail:
And I don't have the expected reboot on node #1.

What st=fail: means ?
Any idea that can block the node from rebooting ?

Thx,
G.

Thx TimO, John, great answers !

Can you shed some light on these msg please

172;255;3;0;11;Humidity + Temp + Relay //<< is the controller that define the 'Humidity + Temp + Relay' ?

172;255;3;0;6;0 //Seems to be an internal::I_CONFIG but why 0 is sent ? shouldn't be I or M ?

172;0;0;0;7;1.4.1
172;1;0;0;6;1.4.1
172;2;0;0;38;1.4.1
172;3;0;0;3;1.4.1
//these are presentation msg but Is the '1.4.1' define in your sketch ? Same as this example 12;6;0;0;3;My Light I don't really understand where the 'My Light' come from

ok so that means the gateway must be online before the sensors start.

You shouldn't really need to care about how the actual gateway/sensors communicate between each other.
I absolutely agree.

Few points I don't really understand are :

• In the communication examples the msg 12;6;0;0;3;My Light\n is, as described, node id=12, sensor id=6, message-type =presentation, for a sub-type=S_LIGHT. But how the 12 and 6 are set ? From the doc I can see that there is I_ID_REQUEST sub-type, so I'm guessing that the controller provide the gateway with a node-id to set on sensor. So before the presentation msg, is there a kind of setup between the sensor and the gateway (In this process the GW may send internal msg w/ a subtype I_ID_REQUEST) ?
• Still with the 12;6;0;0;3;My Light\n example, is the 6 provided by the GW ?
  Is the My Light hard coded on the sensor management program ?
• How can we detect if a sensor is not on the grid anymore ? Has the GW got a routine so it periodically check if all kown nodes / sensors are still available ?

Thx,
G.

Hi all,
I'm about to write my own controller as a personal eduction purpose project.

I read the serial api doc, but I can't find a description how the communication / protocol is organised and more specifically the discovery of all sensors / new sensor occure.

When starting the gateway, is there a broadcast packet sent so that all sensors can answer and notify there online presence ?
How new sensor are discovered ? or notify the gateway ?

Actually, is there a kind of flowchart explaining the communication?

Thank you,
G.
