Port SDK

This topic describes how to port the Tuya Beacon SDK to your project.

Set up environment

• IDE

  Install the required IDE as per the chip manufacturer.

• Hardware environment

  You can choose the development board from the chip manufacturer or use your custom board. ty_iot_beacon_sdk is developed and verified based on the board from the chip manufacturer.

How to port SDK

Port core components

The components layer contains the core stack components of the Tuya Beacon stack, including ty_xxtea, ty_base64, and ty_beacon. Add all static libraries and header files in the components folder to your project.

Implement Bluetooth abstraction layer

Add all files and header files in the bal folder to your project and implement bal_beacon_txrx functions based on the SDK you use. The Tuya standard chip based SDK has implemented the bal_beacon_txrx.

Implement hardware abstraction layer

To store anti-replay sequence numbers and encryption keys and provide the timer function, you need to implement a 256-byte nonvolatile random-access memory (NVRAM) driver and a microseconds system tick driver. For more information about the required function, see Board Layer.

If you use the Tuya standard chip based SDK, you can add the following implemented files to your project.

Implement application layer

The Beacon SDK has implemented the necessary functions on the application layer. You can directly port app_main.c, app_dps.c, and app_dps.h to your project.

Authorize chips

For debugging purposes, you can use the license list to authorize your chips. For more information about the license, see FAQs. Take the AC6329C2 chip as an example. You must comment out the interface for reading the authorization information from the flash memory. Populate authkey[17], mac[6], and pid[9] with the key[0] to key[15], MAC address, and product ID (PID) respectively. You can find the key and MAC address from the license list. The PID is the code assigned to your product created on the Tuya IoT Development Platform.

u8 mac[6] = {0xdc,0x23,0x4d,0x7e,0x35,0xe5};
u8 authkey[17] = "************";
u8 pid[9] = "*******";
u8 version = 0x10;//1.0
u16 kind = 0x0103;

//	get_anthkey(authkey);

	printf("authkey:\r\n");
	put_buf(authkey,16);

//	get_mac(mac);

        ty_beacon_init(mac,authkey,pid,version,kind);

        if(ty_beacon_get_state() == DEVICE_STATE_NOT_PAIRED)
		ty_beacon_start_pairing();
	

Find the app_multi_conn.c file. Shield syscfg_read(NV_USER_MAC_ADDR, ty_ble_addr, 6) and update the value of ty_ble_addr[6] to the MAC address from the license list.

        //u8 tmp_ble_addr[6];
        #if 1
//	u8 ty_ble_addr[6] = {0xe5,0x35,0x7e,0x4d,0x23,0x23};
	u8 ty_ble_addr[6] = {0xdc,0x23,0x4d,0x7e,0x35,0xe5};
	#endif
	#if 0
	u8 ty_ble_addr[6] = {0x18,0x42,0x72,0x4d,0x23,0xdc};
	#endif
	#if 0
	u8 ty_ble_addr[6] = {0x1d,0x42,0x72,0x4d,0x23,0xdc};
	#endif
        /* le_controller_set_mac((void*)"012345"); */
        //lib_make_ble_address(tmp_ble_addr, (void *)bt_get_mac_addr());
        //syscfg_read(NV_USER_MAC_ADDR, ty_ble_addr, 6);

	//hal_flash_read_page(0x3000,6,ty_ble_addr);
        le_controller_set_mac((void *)ty_ble_addr);

        printf("\n-----edr + ble 's address-----");
        printf_buf((void *)bt_get_mac_addr(), 6);
        printf_buf((void *)ty_ble_addr, 6);
