PDP settings for LTE only network

Hello, I have a number of embedded linux boxes with Quectel EC21 4G modems, connected to various cellular networks (AT&T, Verizon, ...). AT&T are removing 3G from some areas and the modems are not reconnecting. My devices are vanishing off the face of the Internet. Quectel have provided some ass

3gpp-set-eps-ue-mode-operation fails to set some options

I'm trying to use the `--3gpp-set-eps-ue-mode-operation` to set `data-centric` or `voice-centric` modes. I note there are 4 possible values: ps-1, ps-2, csps-1 and csps-2, with ps-2 and csps-2 being data-centric. My Quectel E21 modem only accepts one option; csps-2. All other options fail. *Wha

Re: 3gpp-set-eps-ue-mode-operation fails to set some options

Ok, so I might have to talk to Quectel to see what is going on and if there are alternative options. I'm thinking that I'll have to bite the bullet and build ModemManager myself with extra options to accept AT commands, unless I can convince the Debian maintainers to add the extra option as standa

Hi MM devs, *Is there a configuration file for ModemManager?* I'm using Debian Buster.  With Network Manager there is the following. /etc/NetworkManager/NetworkManager.conf /etc/NetworkManager/conf.d/ I can control the log level of NetworkManager by adding a file in the `conf.d/` directory.
