SIM supl追跡

Last updated at Posted at 2014-08-21

flameはQualcomm MSM8210 Snapdragonだという記載を見かける*1*2 のだが、adb shelldmesgしてみると私のは MSM8610v2 らしい。

前回の続き。SIMのsuplについて追いかけてみた。GonkGPSGeolocationProvider などで AGPS_RIL_NETWORK_TYPE_MOBILE_SUPL として現れてくる。そのイベント通知元を次に追いかけてみる。まず/dev/__properties__を眺めてみると、ro.basebandmsmらしい。なので、STR_APQ ではない。TARGET_MSM_NO_SSC に行き着くようだ。で、これはGNSS_MSMNO_SSCで、GNSS_MSM から先は vendor/t2m/flame/proprietary/libgps.utils.so の中にあるようだ。ここからは壁に阻まれてよくわからん…。
