Interface Example:
Name: BT_GEN_FID_SET_SCANMODE_REQ
functionality:
Set Bluetooth inquiry scan and page scan parameter
param 1:
type: |
u8 |
name: |
discover_mode |
|
|
|
|
meaning: discoverable mode
range: 0x00~0x03
0x00: no scan enable(default)
0x01: Enable inquiry scan Page scan disabled 0x02: Enable page scan inquiry scan disabled 0x03: page and inquiry enable
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.
