Hi, I’m porting a GB tablet firmware to JB ( https://groups.google.com/forum/#!forum/renesas-emev-osp) and I’m now stuck at the 3G modem integration. I missed what has been customized in GB (though I can access code), so I have to redo the work myself.
I found Adrien's tutorial (https://afewe.wordpress.com/android-arm-development/use-point-to-point-protocol-ppp-in-android) very useful to this aim, though I still have a few doubts I’d like someone to clarify. 1) what needs to be done, in order to make the connection being triggered by the “appearance” of the ttyUSB* devices, when powering up the modem for example? 2) the chat script invoked by pppd is apparently operator-specific. What should be done to make connection generic and APN-independent? 3) If rild makes the “trick”, what are the parts that are typically customized and what type of info needs to be collected about the specific modem being used (btw, mine is a ZTE MF-212).
