There’s a router device that runs openWRT and has Quectel EC25 on board for sale in my area. Of course I realize that Quectel the company cannot be responsible for something sold by 3rd party business out there but anyways here are few questions I have.
- Am I right to assume the module runs ARM linux and I can program it using quecopen SDK or even upload my own binaries? There are quite a few modifications of EC25, for different regions etc, is the aforementioned functionality restricted to some of them or is it generally expected on every EC25?
- Can the module receive internet/LAN access if the host device (router) is connected to internet? I believe that the module can be configured via USB gadget mechanism (correct me if I am wrong) and can have RNDIS interface in its composition, so can it be connected to outer network via this virtual interface?
- Is the baseband exposed in QMI mode in the internal system ran by the module? I have custom software written in Golang (Go) that involves sending QMI commands, what are chances it could be ran on the module and exchange QMI commands with the baseband?
- Does the module run qmuxd daemon?
Sorry if those questions seem naive or out of place, I never got my hands on this type of LTE module and want to have some idea before buying it.
