# 【Anxinke BW16-Kit】7. Mobile phone search for Bluetooth## 1. Experimental steps This code is used to create an iBeacon device. iBeacon is an indoor positioning system based on Bluetooth Low Energy (BLE) technology. It can broadcast a signal that can be recognized and parsed by nearby devices. The following is a detailed explanation of the code function: 1. **Introduce library**: - `#include "BLEDevice.h"`: Introduce the BLEDevice library, which provides functions and classes for handling BLE device initialization and configuration. - `#include "BLEBeacon.h"`: Introduce the BLEbeacon library, which provides functions for creating and configuring iBeacon beacons. 2. **Define iBeacon object**: - `iBeacon beacon;`: Create an iBeacon object, which will be used to set iBeacon parameters and broadcast iBeacon signals. 3. **Define UUID**: - `#define UUID "00112233-4455-6677-8899-AABBCCDDEEFF"`: Define a UUID (Universally Unique Identifier), which is the unique identifier of iBeacon and is used to distinguish different iBeacon devices. 4. **Set iBeacon parameters**: - `beacon.setManufacturerId(0x004C);`: Set the manufacturer ID of iBeacon. 0x004C is Apple's ID, used for iBeacon. - `beacon.setRSSI(0xBF);`: Set the RSSI (Received Signal Strength Indicator) of iBeacon. This value is used to estimate the distance to iBeacon. - `beacon.setMajor(0x007B);`: Set the Major value of iBeacon. This value is used to distinguish different iBeacon groups at the same location. - `beacon.setMinor(0x01C8);`: Set the Minor value of iBeacon, which is used to distinguish different iBeacons in the same group. - `beacon.setUUID(UUID);`: Set the UUID of iBeacon. 5. **Initialize BLE device**: - `BLE.init();`: Initialize the BLE device and prepare to start broadcasting. 6. **Configure broadcast parameters**: - `BLE.configAdvert()->setAdvType(GAP_ADTYPE_ADV_NONCONN_IND);`: Set the broadcast type to non-connection broadcast, which means that the device only broadcasts data and does not accept connections. - `BLE.configAdvert()->setAdvData(beacon.getAdvData(), beacon.advDataSize);`: Set the broadcast data to the broadcast data of iBeacon. - `BLE.configAdvert()->setScanRspData(beacon.getScanRsp(), beacon.scanRspSize);`: Set the scan response data to the scan response data of iBeacon. 7. **Start broadcasting**: - `BLE.beginPeripheral();`: Start broadcasting BLE signals as a peripheral device, and the iBeacon device starts broadcasting its signals. 8. **Loop function**: - `void loop() { delay(1000); }`: In this example, the loop function only contains a delay because the iBeacon broadcast is automatic and no additional operations are required in the loop. Overall, this code creates an iBeacon device that can broadcast a specific signal by setting various parameters of the iBeacon and initializing the BLE device. This signal can be recognized and parsed by nearby devices for indoor positioning, proximity detection, and other location-based services. ## 2. Code Explanation ```cpp #include "BLEDevice.h" // Import the BLEDevice library to handle the initialization and configuration of BLE devices #include "BLEBeacon.h" // Import the BLEBeacon library to create and configure iBeacon beacon iBeacon beacon; // Create an iBeacon object // Define a UUID, which is the unique identifier of iBeacon #define UUID "00112233-4455-6677-8899-AABBCCDDEEFF" void setup() { // Set the manufacturer ID of iBeacon. 0x004C is Apple's ID for iBeacon beacon.setManufacturerId(0x004C); // Set the RSSI (received signal strength indication) of iBeacon to estimate the distance to iBeacon beacon.setRSSI(0xBF); // Set the Major value of iBeacon to distinguish different iBeacon groups at the same location beacon.setMajor(0x007B); // Set the Minor value of iBeacon to distinguish different iBeacons in the same group beacon.setMinor(0x01C8); // Set the UUID of iBeacon beacon.setUUID(UUID); // Initialize the BLE device BLE.init(); // Configure the advertisement type to non-connection advertisement, which means that the device only broadcasts data and does not accept connections BLE.configAdvert()->setAdvType(GAP_ADTYPE_ADV_NONCONN_IND); // Set the advertisement data to the advertisement data of iBeacon BLE.configAdvert()->setAdvData(beacon.getAdvData(), beacon.advDataSize); // Set the scan response data to the scan response data of iBeacon BLE.configAdvert()->setScanRspData(beacon.getScanRsp(), beacon.scanRspSize); // Start broadcasting BLE signals as a peripheral device BLE.beginPeripheral(); } void loop() { // Repeat the loop every second, but in this example, the loop function is empty because iBeacon broadcasts automatically delay(1000); } ``` ## 3.
