Anyone familiar with the Waveshare GSM/Bluetooth Hat?

[lekston]

Hi,

I purchased the GSM/GPRS/GPS hat for my PI3B+ and a low cost SIM from french local provider. I had some difficulties to establish a serial communication. The working configuration is (from my laptop at this stage)
- set the jumper to A (USB <=> serial)
- check usb connection using dmesg | grep USB
- chmod 777 /dev/ttyUSB0 (i don't know if it realy requiered but now it works)
- putty serial /dev/ttyUSB0
I don't know why minicom seem not working but for my tests on PI, I would need it (I connect to my PI throu ssh) and putty requires a X server.

Now I have a big issue : few seconds after entering my pin using AT +CPIN=<my pin here> hat shuts down (yet hat telling me that call and sms are ready) .

Does anybody encountered the same issue?

Thank you for this interesting link.
Actually, it seems the USB <=> UART connection delivers not enough power during GSM startup phase (just after entering the PIN code) and very often, it simply shuts the hat down. Hopefully UART works perfectly. Nota: don't forget to enable serial communication and disable the "serial login" in the rasp-config.
