+
+## Table of Contents
+
+## 一、The conditions of use
+> * Minimum version iOS 8.0
+> * The Bluetooth version used by the device requires 4.0 and above.
+## 二、Use
+1. Apply the key and secret of sdk, application address: http://sdk.aicare.net.cn;
+2. Add "Privacy-Bluetooth Always Usage Description" to the info.plist file;
+3.Import TPSMSleSDK.framework into the Xcode project.
+4. Enter the following code in AppDelegate:
+```
+#import <TPMSBleSDK/ELTPMSBleManager.h>
+
+- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
+    // Override point for customization after application launch.
+    [ELTPMSBleManager setAppKey:@"key" appSecret:@"secret"];
+    return YES;
+}
+```
+5.Set the bitcode of the build setting to NO
+6.Import "#import <TPMSBleSDK/ELTPMSBleManager.h>" to the controller you want to use, and follow the "<ELTPMSBleManagerDelegate>" protocol.
+7.Set delegate
+```
+[ELTPMSBleManager shareManager].delegate = self;
+```
+8.Implementing proxy method
+```
+ -(void)TPMSBleManagerUpdateBleState:(TPMSBluetoothState)state;
+-(void)TPMSBleManagerReceiveData:(ELTPMSDataModel *_Nonnull)model;
+```
+   
+## 三、Get broadcast data
+### 1.Determine if the phone Bluetooth is available
+Proxy method：
+````
+-(void)TPMSBleManagerUpdateBleState:(TPMSBluetoothState)state;
+```
+Get the current Bluetooth status
+Or
+```
+[ELTPMSBleManager shareManager].isOn
+```
+Get current Bluetooth enabled is available；
+### 2.Start scanning
+```
+[[ELTPMSBleManager shareManager] startScan];
+```
+### 3.Stop scanning
+```
+[[ELTPMSBleManager shareManager] stopScan];
+```
+### 4.Method description
+```
+-(void)TPMSBleManagerUpdateBleState:(TPMSBluetoothState)state;
+```
+  This method is used to get the current state of Bluetooth, where the parameter "state" is an enumeration TPMSBluetoothState
+   The enumerated elements include: TPMSBluetoothStateAvailable (Bluetooth on TPMSBluetoothStateUnavailable), TPMSBluetoothStateBroadcasting, TPMSBluetoothStateStopBroadcasting
+```
+ -(void)TPMSBleManagerReceiveData:(ELTPMSDataModel *_Nonnull)model;
+```
+This method is used to call back the TPMS Bluetooth module broadcast data. The model is an ELTPMSDataModel data model. For details on the ELTPMSDataModel class, please see "Remarks".
