unable to open file '/etc/bluetooth/ble_stack.conf': No such file or directory

Hi All,

   After Porting Bluetooth driver in android platorm, we enabled Bluetooth from GUI. We were able to BT devices and pair/unpair, data transfer is working properly. But we couldn't see BLE devices in Scan results and We are getting BLE configuration file is not found.

Error:

Could anyone help to enable BLE and How to get ble_stack.conf file ?.

Hello Thanaraj,

    Our android BSP doesn't use ble_stack.conf, but bt_stack.conf & bt_did.conf.

Have a great day,

Hi Weidong Sun,

   Do you mean to say BLE is not supported, only BT support is there ?

   Eventhough we were not able to see BLE scan results. Can you please tell, how to enable BLE if Android supports BLE ?

Regards,

Thanaraj.
