The interface command name is BT_GEN_FID_SET_SCANMODE_REQ. There is one paramer named discover_mode with four valid values and below is the description of all values.User can configure ScanMode of X-8075 by sending this
interface. When Host Controller initiates a REQ, BT Module should always send a corresponding CFM to specify operation result and optional additional information. Example:
BT_GEN_FID_SET_SCANMODE_REQ<discover_mode=0x03> BT_GEN_FID_SET_SCANMODE_CFM<status=0x00>
Set discover_mode as 0x03, then other Bluetooth device can find X-8075 and initiate to pairing with X-8075.
