TK918 with watch protocol keep alive

renaud9 hours ago

Hello,

I have multiple TK918/LK209C 4G devices. They all seem to be fine except some which send keep alives every 5 minutes even when in sleep shock mode. Is there a way to disable this? The device documentation doesn't show anything for this.

I get this kind of message every 5 minutes when the vehicle is stopped and this obviously consume data and drain battery. Besides, traccar show those devices as online.

It looks like keep alive messages, but I have no idea how to disable this.
Other trackers also do it, but only once a day.

Thanks
