radio firmware (radio processor side) -> ril driver (app processor side) -> rilj -> dialer Some of the ril driver code lives in hardware/ril/libril/ril.cpp in the AOSP code but the interesting parts are in the OEM binary blob. > Is there a similar mechanism to wake my application up when data is > received via an active TCP connection to a server, even after the > phone has gone to sleep mode ? As far as I know there is no similar mechanism available to anybody that doesn't have access to a way to modify the OEM binary blob for whichever hardware bits are under the TCP connection (WiFi or cell radio.) -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
