We made 5 prototypes recently with the BG95-M3 and we are having some issues to get them working.
When we connect the usb we only see one COM port -> Qualcomm HS-USB Diagnostics.
So we are a bit confused because we need the AT/DM ports but they are not showing up.
Voltages look OK and the PWR key functionality works.
Boot pin is not connected, so this is not the emergency download mode?
Could we have made a PCB mistake? Does the modem maybe have just no firmware on it?
