beta

uint16_t bt_conn_set_pcr_params::beta

Value used to determine the weight of the previous average of RSSI values. A higher value lowers how much the current RSSI weighs into the average, flattening peaks, which also means the controller reacts slower on RSSI changes. The valid range is [0, 4095]. Default value is 2048.

In the controller, the value is used in an exponential weighted averaging of RSSI in a 12-bit fixed point fraction.

avg[n] = gamma * avg[n - 1] + (1 - gamma) * rssi[n]

Here, gamma equals beta/4096, and rssi[n] equals the current RSSI.

For example, for gamma to be 0.25, set the beta parameter in the command to 1024.
