I see in the HL78 PTS that there is a AT_PPP port over USB, i guess is dedicated to ppp, can you give some guidelines to use this port and ppp? (HL78-Linux/Windows host)

you can see these two topics on +KUSBCOMP command:
Normally new FW is updatable but before that please provide your result ATI9, AT+KGSN=2(IMEI), AT+KGSN=3(FSN).
Yes. Youu can set USB ONLY without UART1 at all by (AT+KUSBCOMP=1.
(debug port UART0 is not impacted)
Here’s the syntax:AirPrime - HL78xx - AT Commands Interface Guide - Rev8.1.pdf (1.9 MB)
AT+KUSBCOMP=
USB mode config
0 USB disabled (default)
1 3 CDC-ACM mode (PID: 0xC001)
USB-ACM0 - AT/PPP port
USB-ACM1 - PPP data port
USB-ACM2 - NMEA data port
Notes
The configuration is …
Hi @gustav.sohtell ,
I assume that HL7800 is already in USB mode. You can confirm this with AT+KUSBCOMP? command. If it returns “1”, that means device is in USB mode.
Once in USB mode, you will see three ttyACMx ports. Typically, ttyACM0, ttyACM1 and ttyACM2.
USB-ACM0 — AT port
USB-ACM1 — AT/PPP data port
USB-ACM2 — NMEA data port
I will recommend to you ACM1 as your PPP port.
You will also need PPP daemon installed on your host. Check that pppd is available with pppd version
Check th…
