Please provide protocol documentation.

You can access protocol at : https://drive.google.com/file/d/1vKBWhU6b3SmRzjpU5LFsZe5ooyPlCOKA/view?usp=sharing

You need to make it public.

Sorry, can you try again now? I change permissions to public.

Yes, it's "watch" protocol, port 5093 in Traccar.

Ok i guess when i edit device server parameters and redirect device public traccar server on 5093 port it works right? What about authentication on device to traccar server?

Dear Anton, Thank you for fast response and your help.

I have another question about this device. Approx 5 minute before i have complete traccar server installation on my public linux server. A9 devices have embed micophone. How can i listen (or call this device) and recieve sound data with traccar API it's possible?

You should be able to receive audio and store it in a file on the server. You might need to wait for the next release to actually access those files via API. That's something we implemented recently.

Thank you for answer. How can i send command to device. I already share communication protocol for this device but i cannot send command directly device. It have SOS functionality like "Slient Call SOS Number e.t.c" maybe i can use these functions until new traccer release.

What do you mean how? There is web interface and there is API for commands as well.

When i read communication protocol documentation i see this step (below) how can i send [3G*8800000015*0007*MONITOR] command on traccar web interface?

5.Listen in/ Monitor
Platform send:
[CS*YYYYYYYYYY*LEN*MONITOR]
Example:[3G*8800000015*0007*MONITOR]
Device Response: [CS*YYYYYYYYYY*LEN*MONITOR]
Example:[3G*8800000015*0007*MONITOR]
Note:device automatic callback the center number. Platform send:

You send it as a custom command.
