Hi,
I Have A raspberry PI4 with debian Buster using a Sixfab Base Hat with Quectel EC25-E.
I’m trying to get a ppp connection running from France.
I ran the ./ppp_install_standalone.sh
Choose 6 as it’s a base Hat, then enter my APN correctly. I chose ttyS0 as I want it to work without USB connected (I did enable I2C, disable serial port login shell and enable serial port prior to it).
I checked my SIM card for the datas, disabled pincode, and the simcard is working when I use it on other devices.
I also checked with another working SIM card from another operator but nothing works !
When I run “sudo systemctl status ppp_connection_manager.service” the service is running but I get some errors :
● ppp_connection_manager.service - PPP Connection Manager

It looks like there is some syntax error in your script “configure_modem.sh”…
I didn’t find anything about these errors on your troubleshooting.
I’m stuck with this for more than 48h now… I’m running out of time !
Can you help me please ?
