GPS is there for sure, it can be accessed with at least mmcli with ModemManager running assuming modem instance 0: $ mmcli -m 0 --enable $ mmcli -m 0 --location-enable-gps-raw $ sudo chmod a+r /dev/cdc-wdm0 Then configure gpsd to use /dev/cdc-wdm0. But having a dedicated NMEA port would be nice. Any ideas how the GPS port might be enabled for ttyUSB, should it start just printing out data if GPS is enabled? FYI, selecting the "BP HW Diag & Boot AP" option from bootloader with the volume buttons routes the whole modem to the OTG USB interface with the same ports available to PC so that's probably for cert use. If needed we can do this from Linux too by just by setting one of the USB PHY pins high with cpcap_usb_gpio_set_mode(). Regards, Tony

And after some searching the the three unknown ports seem to be NMEA, TCMD and MUX in some unknown order. No idea what the TCMD and MUX are here. Looks like /dev/ttyUSB3 pretty much just echoes back the characters typed in. Regards, Tony
