I’m using [LTE Cat.1 6 Click](https://www.mikroe.com/lte-cat1-6-click) with a SIMCom [SIM7600SA](https://download.mikroe.com/documents/datasheets/SIM7600_datasheet.pdf) module on it. ModemManager is giving me some grief with it on BalenaOS 6.5.2. ```auto root@89dd143:/sys/devices/platform/bus@f0000/2850000.serial/driver# udevadm info /dev/ttyS0 P: /devices/platform/bus@f0000/2850000.serial/tty/ttyS0 N: ttyS0 L: 0 E: DEVPATH=/devices/platform/bus@f0000/2850000.serial/tty/ttyS0 E: DEVNAME=/dev/ttyS0 E: MAJOR=4 E: MINOR=64 E: SUBSYSTEM=tty E: USEC_INITIALIZED=6652393569 E: ID_MM_CANDIDATE=1 E: ID_MM_DEVICE_PROCESS=1 E: ID_MM_TTY_BAUDRATE=115200 E: ID_MM_PORT_TYPE_AT_PRIMARY=1 E: ID_MM_PORT_TYPE_AT_PPP=1 E: ID_MM_TTY_FLOW_CONTROL=none E: TAGS=:systemd: E: CURRENT_TAGS=:systemd: root@89dd143:/sys/devices/platform/bus@f0000/2850000.serial/driver# /usr/sbin/ModemManager --debug ModemManager[9957]: [1758687644.371849] ModemManager (version 1.22.0) starting in system bus... ...
