Sendig AT command after switching and before pppd connection

Post by Mik » 26 Sep 2019, 15:12

Hi there,
I've a raspberry pi connected with an E3531 Huawei dongle in VPN through the sakis3g script.
I need to lock the network selection to 2g only (I found this AT command to do so AT^SYSCFG=mode, order, band, roaming, domain). Is there any way to inject automatically this command just after the switching at reboot?

Thank you in advance

That depends on which distribution you are using which in turn determines the version of usb_modeswitch.

The original (upstream) version distributed here uses a text-only script in the Tcl language as the dispatcher. It is very easy to call external scripts after the mode-switch was confirmed.

Distributions are applying various changes; e.g. Ubuntu has re-implemented the dispatcher in C so it's a bit harder to extend it, requiring compilation.
