Question

Hi,

Seeing occasional SMS messages from TRB140 "reboot request from UART" but there is nothing connected to the serial port.

Latest firmware installed.

Is this a known issue?

Answer 1

Hi,

Did you try resetting your device and see if the message still comes up?

Are you aware of the batch / hardware revision of the device? If yes, could you tell me? If you do not know - you can just send me your troubleshoot file via private message.

Thanks.

Is there are reference example showing the CLI commands to get the troubleshoot file?

It would be easier if you've done it through WebUI - you should find it under System > Administration > Troubleshoot.

Any update on this topic? We experienced the same behaviour (sudden reboot and "reboot request from UART" on the system events after reboot) but I found no reference of any reboot activated by UART in the Teltonika documentation: we used time activated reboots and ping reboots in other devices but this sudden reboot caused by serial is a first.
