    Hi Mark,

    Thanks for your reply.

    I’ve attached the output when using “tail -f /var/log/syslog” after enabling the data connection using “sudo pon”. Prior to this I have enabled multiplexing using “sudo gsmMuxd”.

    Hello,

    When starting gsmMuxd I see the following errors:

    2024-03-19T13:35:58.350436-07:00 backpack gsmMuxd[1960]: Modem does not respond to AT commands, trying close MUX mode

    2024-03-19T13:36:02.390414-07:00 backpack gsmMuxd[1960]: MUX mode doesn’t function.

    2024-03-19T13:36:02.393769-07:00 backpack rc.local[1959]: MUX startup failed. See syslog for details.

    Ok I see the error above when starting gsmMuxd is the known issue after restarting. From a cold start it works.
