Last Updated on : 2022-11-24 09:20:07download

The components layer contains the core stack components of the Tuya Beacon stack, including ty_xxtea, ty_base64, and ty_beacon.

Components	Description
`ty_xxtea`	Used to encrypt data, serving the `ty_beacon` component.
`ty_base64`	Used to decode the base64-encoded data, serving the `ty_beacon` component.
`ty_beacon`	Serves the core Beacon communication protocol.

ty_beacon_init

Function	ty_beacon_init
Feature description	Used to initialize the Tuya Beacon stack.
Parameter	`u8 pmac`: the 6-byte MAC address. `u8 pauthkey`: the 17-byte `authkey`. `authkey` is 32 bytes actually but only `authkey[0]` to `authkey[16]` are the valid values. `u8 *ppid`: the 8-byte `product ID (PID)` of a product created on the Tuya IoT Development Platform. `u8 version`: the SDK version number. `u16 kind`: the category and type of a product. For example, `0x0103` represents colored light (RGB), where `01` represents the product category of lights and `03` represents the product type of colored light (RGB).
Return value	None
Note	This function is called where program initialization is performed.

ty_beacon_download

Function	ty_beacon_download
Feature description	Used to receive and process the data from the cloud.
Parameter	`u8 *rxbuf`: the raw Beacon data, including the 2-byte header, the 6-byte MAC address, and the payload data of up to 31 bytes. `u8 len_pdu`: the length of raw Beacon data. `u8 rssi`: the received signal strength.
Return value	None
Note	This function is called where the Beacon receives a callback.

ty_beacon_send

Function	ty_beacon_send
Feature description	Used to send data in packets on a schedule.
Parameter	`u32 cycle`: the packet interval, in microseconds. `u8 send_times`: the number of times that packets are sent. `u8 cmd`: the command included in the packet. `u8* params`: the parameter included in the packet. `u8 params_len`: the length of the included parameter. `u8 tp`: 0
Return value	None
Note	This function is called where DP data is reported.

ty_beacon_start_pairing

Function	ty_beacon_start_pairing
Feature description	Used to enable the device to enter the pairing mode that lasts for three minutes.
Parameter	None
Return value	None
Note	This function is called for triggering device pairing.

ty_beacon_get_state

Function	ty_beacon_get_state
Feature description	Used to get the pairing status.
Parameter	None
Return value	`DEVICE_STATE_PAIRING` `DEVICE_STATE_PAIRED` `DEVICE_STATE_NOT_PAIRED` `DEVICE_STATE_REP_GET_BEACONKEY` `DEVICE_STATE_REP_GET_PAIRING_OK`
Note	This function is called to request the current pairing status.

ty_beacon_run

Function	ty_beacon_run
Feature description	The Beacon stack driver.
Parameter	None
Return value	None
Note	This function is called periodically with high frequency.
