Hi, Is there any guide out there to help with connecting the PCI cellular modem on a Raspbian for FIN? Thanks,

@xginn8 @imrehg Cellular service is showing connected on the same board I have been using under BalenaOS. Partial mmcli -m 0 output: Status | lock: sim-pin2 | unlock retries: sim-pin (3), sim-pin2 (10), sim-puk (10), sim-puk2 (10) | state: connected | …

Hey @Jgilbert seems the core of the issue was that modemmanager is too old in the Raspbian Stretch image (v1.6.4). We tried out updating the OS to Buster on a device, and update to the latest modemmanager there (v1.10.0) which is much newer, and it worked fine. The update in the current Raspbian im…

@xginn8 @imrehg - I followed the suggestions above. On initial installation of Raspbian (standard), I had both wireless and LAN connectivity. Once I did the “apt update” and “apt full upgrade”, I lost both of those connections, and was unable to install modemmanager (although Raspbian did recogniz…

@xginn8 @imrehg - I reran through the steps above, and was able to connect the modem to the cell network using both modemmanager and networkmanager. I will put the directions here, once the issue with losing the wireless connection during upgrade has been answered. Not sure what will change, if any…

Hi again @jgilbert , and thanks for the update! I’ve pinged some folks internally for more information on the other thread you mention, so stay tuned there for any updates. Please do provide those directions whenever you are comfortable posting them :slight_smile:

Hi there, I got EC-25 working in Raspbian on Fin 1.1 the other day. You need to set the interface to raw IP mode (ppp by default). I got the details from https://www.embeddedpi.com/documentation/3g-4g-modems/raspberry-pi-sierra-wireless-mc7455-modem-raw-ip-qmi-interface-setup Works if connected dir…

@xginn8 @imrehg There is an updated version of Raspian available at the end of this thread: Connect to wifi . Everything seems to be working fine at this point. I am running through various configurations, and should be able to post the basic directions soon. Thanks!

Hi I’m at the same point (using ubuntu 16.04 due to other constraints, modem manager 1.6.4, no sim but otherwise shows the device - same output as you, slightly different Hardware.revision). I’m currently building from source the libqmi, libmbim and ModemManager to the latest (1.2.4) and hope to h…

Does anyone here know what to do with this policy kit error? $ mmcli -m 0 -e error: couldn’t enable the modem: ‘GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Failed: PolicyKit authorization failed: ‘GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Action org.freedesktop.ModemManager1.De…
