Hi,
I have a device connect to 4G LTE, it was in good connection status on
start up, after a couple of hours, it dropped LTE connection, the
ofono did not show any errors, but connman had lots of error messages
at following, could any one help to explain what could be the problem?
Could it be ofono issue or connman issue? The device has small flash
size which don't have enough space to debug tools.
# journalctl -u ofono
