I observe a reset of the modem (radio turning off) when I connect the Fx30 to a Windows10 PC.
I would like to avoid the PC connection interfering with Fx30 connection state. I only need the ECM and DIAG on the USB.
It is reproducible 100%. I tried it on a clean Fx30 out of the box.
It is the same on the firmware R14 or on my customized firmware.
Firmware: SWI9X15Y_07.11.22.00 r33729 CARMD-EV-FRMWR1 2017/01/11 18:04:06
Bootloader: SWI9X15Y_07.11.22.00 r33729 CARMD-EV-FRMWR1 2017/01/11 18:04:06
In an attempt to remove this problem, I have reduced the USB composition from its default value 0008011D (diag,nmea,modem,at,rmnet0,ecm) to 00080101 (diag,rmnet0,ecm) using the AT command USBCOMP.
With this configuration, Windows contines to see a DM port coming from the Fx30 and continues to reset the modem.
The AT command returns an error when I try to remove “rmnet” from the USB composition.
Could you tell me how stopping the Fx30 from receiving modem controls from the PC?
Remark, I am not searching a solution on the Windows side, as I have many users connecting to the Fx30 with their PCs, I would prefer finding a solution on the Fx30 side.
