Hi,

How to increase the receiver sensitivity level in observer role? I had seen Tx power level in ble_user_config.c but i can't find for Rx sensitivity.

You can try to use HCI_EXT_SetRxGainCmd to do this.

Hi YK Chen,

Thanks for the reply, what parameters I have to give and where I have to call this API? Is there any reference code or reference page to that API.

Regards,

Vijay Rakesh

Oops! Just find out it's not supported by CC26xx device. You can refer to the discussions in e2e.ti.com/.../610602

Hello Vijay,
There is an AGC enabled and gain is optimally configured through overrides in the BLE stack. There is no need to change these or add anything. If you have a custom board you can improve the antenna design and make sure RF matching is optimal. The scanning timing parameters will affect how fast you catch advertisements. Please refer to this thread post for more details:
