1 Features An ultra-low power beacon device that supports iBeacon and Eddystone UID & URL. 2 APP communication protocol APP sends instructions to the Beacon module through the FE61 channel. After receiving the instructions, the module parses and executes the instructions, and returns the result of the instruction execution to the APP through the FE62 channel. The whole process is shown in the following figure. Figure 2 1 APP operation Beacon flow chart 2.
04 FC xx xx xx xx……xx Start character: all command frames must start with "01 FC", and all response frames start with "04 FC". Command ID: The IDs of commands with different functions are unique. The following is an enumeration and detailed explanation of all commands. Command length: The input frame length is the number of bytes of the input frame command parameters, and the response frame length is the sum of the execution status and the length of the response data.
Name: The name of the device, usually a visible string. Return: 04 FC 03 01 status 04 Query Format: 01 FC 04 00 device Returns: 04 FC 04 len status [Name] / name 05 Set the uuid 06 Format: 01 FC 05 len uuid YES len: 1-byte unsigned integer, the length of uuid, fixed at 0x10. Big endian. broadcast uuid: 16-byte unsigned integer, beacon specific uuid.

4.2.2 Eddystone Broadcast format 4.2.
Type is a value with a common standard. You can check the meaning of the specific number on the official website of the Bluetooth Alliance. The commonly used ones are as follows: Incomplete 16Bit service UUID (0x02), incomplete 128Bit service UUID (0x06), device full name (0x08), device abbreviation (0x09), vendor-defined data (0xFF), ··· When setting a custom broadcast, the broadcast data must conform to the format of the user data unit shown in the figure above, otherwise the setting cannot be successful.
4.4 Mode setting Beacon has two modes: deployment mode and factory mode Factory mode: In this mode, the device connection does not require an authentication process. Deployment mode: After switching to this mode, the device needs to complete authentication within 10 seconds after being connected. The authentication method is to write the same configuration key as set in the authentication channel to complete the authentication. If the authentication fails Pass to disconnect. 4.
