So, a recent hot topic in the CDMA Diamond/Touch Pro world is the FM Radio – Here’s what my research has shown so far:
The Bluetooth chipset (BRF6350) on both devices support FM Radio+RDS, but need an antenna provided by the headphone to operate.
I’ve got the FM Radio to work perfectly on the Diamond, and will release nueROM-S for the Diamond that supports the FM Radio.
HOWEVER, the Touch PRO is a different – I suspect that either the radio gpios are disconnected completely, or radio support is disabled in the SPL.
As to why Sprint/HTC decided to take out the FM Radio, I’m not sure… Perhaps they had difficulty obtaining FCC approval, I’m not sure… Or maybe HTC wanted more money to include the FM Radio….
