It is uBlox SARA-R4 chipset, did you mean it could be caused by weak
LTE signalling level? It is a prototype device, the hardware was
designed by an contractor. Any simple way to show LTE signalling level
in connman or ofono log files? The trouble is it connected well at
startup, then dropped it, it is hard to convince the hardware
contractor it is hardware problem unless I have strong evidence that
is not the software problem.

Thank you very much.

Kind regards,
