Qualcomm TAVARUA FM.... Very interesting, I haven't seen any other phone using this device. The "Code Aurora" (Quicinc / Qualcomm) FM app from which mine is derived contains code for that chip and no other. So it's possible. If Huawei didn't sabotage it, intentionally or not.
Very strange FM story on this device. As dancer_69 pointed out, this official spec page clearly says "FM Radio ... Supported" : http://www.huaweidevice.com/worldwid...ctId=3547&tb=0
But some on this thread indicated Huawei employees were saying it won't be supported, or wasn't capable of FM: http://forum.xda-developers.com/show....php?t=1057214
Perhaps they decided not to support it for some reason, possibly even due to hardware issues that might prevent proper operation.
But that official Huawei web page and the fact that it has a kernel driver seem to indicate they were planning to support FM.
Information on Tavarua is hard to find. The best info is the source code in the Code Aurora FM app and some kernels contain the driver in these files:
This seems to be a V4L driver with quite a few private Ioctls. Is the device name /dev/radioX or /dev/marimba_fm or similar ?
Not much info on Qualcomm website except this: http://www.qualcomm.com/products-ser...ivity/fm-radio
FM support is provided on:
* WCN2243 (BT/FM SOC)
