I have IOT2050 Basics FS:04 and 4G modem Huawei ME909s-821 . The operation is correct. But after a few days working correctly on some devices, not all IOTs, when restarting the OS, the ModemManager application stops starting properly and does not detect the modem, although the OS has detected the modem correctly and the NetworkManager has runned the ModemManager application. Looking at the syslogs, the error starts when a line that should appear does not appear, compared to other devices that do work: ModemManager[342]: opening device... From this line, which no longer appears, the following Modemmanager lines no longer appear either. Then the IOT fails to connect to the internet. I restart the OS but the Modemmanager never starts well. The only solution I have is to remove voltage and apply it again, then the ModemManager does start fine. I would really appreciate it if someone could shed some light on this problem, I don't know where to start looking to fix it. If anyone has been through this or has any ideas I would appreciate any feedback as I am pretty lost. thanks in advance, Edu AttachmentKO+OK.zip (215 Downloads) |

Is that modem operating via USB or PCI (via the miniPCI or M.2 slot)? |
