I'm afraid this is not as easy as it seems; the change would not be to just configure to use DHCP on the net interface. When in ECM mode, you're expected to use some vendor-specific AT commands to bring the connection up in that interface, before we can request DHCP on it. When a plugin doesn't implement the vendor-specific AT commands to bring up ECM interfaces, as in your case, the plugin falls back to AT+PPP. Adding the AT support for that ECM mode would be done through a new Quectel specific "bearer" object, implementing both connect_3gpp() and disconnect_3gpp() at least. If the modem supports QMI or MBIM, using those would anyway be preferable, as they're fully supported in the codebase already. -- Aleksander https://aleksander.es
