Server sends audio, JC181 plays on speaker — which command does Jimi actually use?
I think the command is the same and video streaming. There's just another bit you can set.
Interesting — that sounds promising.
Do you happen to have:
any sample code,
JT808/JT1078 command reference,
packet structure,
or protocol documentation
for the JC181 audio talk command?
Protocol documentation you should be able to get from your device vendor. And I don't have any code samples.
Got it, thanks.
Unfortunately the vendor documentation I have doesn’t mention the one-way audio playback part at all, even though Tracksolid Pro clearly supports it on the device.
Since you mentioned it’s basically the same as video streaming with another bit set, do you remember:
- where that bit is located,
- or any related message ID involved?
First of all — huge thanks to the Traccar team for the LiveStream feature.
Now the question. I'm looking for help implementing one-way audio playback on a Jimi JC181 dashcam The use case is simple: server sends audio bytes, device plays them through its built-in speaker. No return audio needed — not building two-way intercom. Just a one-way broadcast like "dispatch to driver."
Confirmed the hardware supports it: Jimi's own Tracksolid Pro app does exactly this during a live video stream — pressing the in-app button makes audio play from the JC181's speaker. So the path exists. I just can't figure out which JT/T 808 message ID and JT1078 frame format the device actually accepts.
