Porting Btstack to Android Device

[jup...@gmail.com]

Hi Matthias:

I have done some tests with the /port/mtk example, and it's works fine with my Android Phone(with mtk's bt chipset on board),but for phone whose bt chipset from other vendors(such as Broadcom、Qualcomm、CSR and so on)，it will not work because there is no libbluetoothdrv.so in /system/lib.

So is there another way to integrate btstack in these phones ? 

ps:

 I found a bluetooth test application named “bdt” (/externals/bluetooth/bluedroid/test) which link against bluedroid ,can i use it as btstack's hci-transport interface ? 

Thanks!

Hi

The port/mtk was custom port to a particular Android device. In general, BTstack can run on Android if it gets access to the Bluetooth module. 

I recently stumbled upon this page: https://source.android.com/devices/bluetooth and also did some digging around the lower layers of Bluedroid. It indicates that vendors need to provide a libbt-hci. So, if this library is present on all Android devices, it should be straight forward to interface with that from BTstack. Look like it refers to https://android.googlesource.com/platform/external/bluetooth/bluedroid/+/master/hci

Best
