Discussions about rSAP on phones with MediaTek chipset
Currently I don't think there is much demand for my app on these phones, so the (possibly huge amount of) work will not be worth it. And I don't know if a solution for the inew will also work on other Mediatek phones.
The problem with the MTK phones is that they have a completely different Bluetooth stack. So far I could not find out how to disable built-in profiles (rSAP is built-in!) to enable my app(s). I'll try further, but it looks rather unlikely that I'll succeed.
