BT_GEN_FID_SET_SCANMODE_REQ

param 1:

type:

meaning:

range:

0x00: no scan enable(default)

0x01: Enable inquiry scan Page scan disabled

0x02: Enable page scan inquiry scan disabled

0x03: page and inquiry enable

discoverable mode

0x00~0x03

name:

discover_mode

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 YWX5057 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 YWX5057 and initiate to pairing with YWX5057.
