I would like to achieve TX-POWER control using GPIO mode GAIN control on the application core in SDK_VerV2.8.0, similar to how it was done in V2.3.0.
Could you please tell me how to set the TX-POWER in SDK_VerV2.8.0?
The API "ble_hci_vsc_conn_tx_pwr_set" is not available in SDK_VerV2.8.0.
"HCI_OPCODE_VS_SET_CONN_TX_PWR" also returns "BT_HCI_ERR_UNKNOWN_CMD".
