blecomm-api.jar
可实现与模拟蓝牙设备实现基本的收发通讯的基本方法,本样例就是一种基于api的实现方法.
- android 最低支持的版本:
Android 5.1 (LOLLIPOP_MR1 API22) - ble peripheral 支持
目前同时用到ble的Central角色和peripheral角色,所以在android版本满足的前提下,还需要检测手机是否支持peripheral角色,参考如下:
MainActivity.java
private void ensureBleFeaturesAvailable() { BluetoothManager mBluetoothManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE); BluetoothAdapter mBluetoothAdapter = mBluetoothManager.getAdapter(); if (mBluetoothAdapter == null) { Toast.makeText(this, "Bluetooth not supported", Toast.LENGTH_LONG).show(); Log.e(TAG, "Bluetooth not supported"); finish(); }else{ Log.i(TAG, "Bluetooth supported"); } BluetoothLeAdvertiser mBluetoothLeAdvertiser = mBluetoothAdapter.getBluetoothLeAdvertiser(); if(mBluetoothLeAdvertiser == null){ Toast.makeText(this, "the device not support peripheral", Toast.LENGTH_SHORT).show(); Log.e(TAG, "the device not support peripheral"); finish(); } else{ Log.i(TAG, "the device support peripheral"); } }
- bleStartAdvertisementSimulate
- bleStopAdvertisement
- bleStartConnect
- bleDisConnect wear
- bleSendMessage
- onReceive
- onStartSuccess
- onStartFailure
- onSendSta
- 在bulid.gradle中加入
blecomm-api.jar的依赖 - 需要在manifest中加入蓝牙相关权限
- 需要在manifest中注册com.wearlink.blecomm.BleService服务
- 在activity用如下方法开启服务:
((BleService.MyBinder)service).getService() - 开启服务同时,用如下方法设置以实现的接口
onServiceProgressListener:bleService.setOnBleCommProgressListener(onServiceProgressListener); - 在此接口的
onServiceOpen方法中通过如下方法获取主要方法接口:bleService.getBleCommMethod();
由BleCommMethod接口提供:
/**
* ble communication method
*/
public interface BleCommMethod {
/**
* ble communication session open
* @param device_name : device name
*/
void bleOpen(String device_name);
/**
* ble communication session restart
* @param device_name : device name
*/
void bleRestart(String device_name);
/**
* ble communication session close
*/
void bleClose();
/**
* get now ble communication operator
* @return byte : operation mode
*/
byte bleGetOperator();
/**
* ble advertisement start by special device name
* only simulate method because ble communication session
* support device need equal LE General Discoverable Mode and
* BR/EDR Not Supported.
* @param device_name : device name
*/
void bleStartAdvertisementSimulate(String device_name);
/**
* ble advertisement stop
*/
void bleStopAdvertisement();
/**
* ble communication connect requirement
* @param device_addr : device mac address
* @param conn_pass : ble communication pass word
* @param time_out : ble connection timeout
*/
void bleStartConnect(String device_addr, byte[] conn_pass, int time_out);
/**
* ble communication disconnect requirement
*/
void bleDisConnect();
/**
* ble communication send message requirement
* @param dat : ble send message
* @param len : length of send message maximum is 15 bytes.
*/
boolean bleSendMessage(byte[] dat, byte len);
}由OnBleCommProgressListener接口提供,客户可根据需求重写相应方法:
/**
* ble communication progress listener interface.
*/
public interface OnBleCommProgressListener {
/**
* scan device return
* @param device_address: device mac address
* @param device_name : device name
* @param adv_flag : advertisement flag
*/
void onScanDevice(String device_address, String device_name, byte adv_flag);
/**
* scan device return
* @param device_address: device mac address
* @param errorCode : BLE_ERROR_OK or BLE_ERROR_CONNECTION_TIMEOUT
*/
void onConnection(String device_address,int errorCode);
/**
* scan device return
* @param device_address : device mac address
* @param errorCode :
* BLE_ERROR_OK : response for OPER_DISCON_REQ
* BLE_ERROR_CONNECTION_TIMEOUT
*/
void onDisConnection(String device_address, int errorCode);
/**
* ble communication send message requirement
* @param dat : ble receive message
* @param len : length of receive message maximum is 15 bytes.
*/
void onReceive(byte[] dat,int len);
void onSendSta(int code);
/**
* service open success callback
* ble communication core is a service named BleService
* user need start it in user's Activity like this:
* ((BleService.MyBinder)service).getService()
* and register service in manifest like this
* <service android:name="com.wearlink.blecomm.BleService"/>
*/
void onServiceOpen();
/**
* ble communication requirement success
* @param Oper :
* OPER_ADV : bleStartAdvertisementSimulate
* OPER_CON_REQ : bleStartConnect
* OPER_DISCON_REQ : bleDisConnect
* OPER_TRAN : bleSendMessage
*/
void onStartSuccess(byte Oper);
/**
* ble communication requirement failed
* @param Oper :
* OPER_ADV : bleStartAdvertisementSimulate
* OPER_CON_REQ : bleStartConnect
* OPER_DISCON_REQ : bleDisConnect
* OPER_TRAN : bleSendMessage
* @param errorCode : BLE_ERROR_INVALID_PARAMETER or BLE_ERROR_INVALID_OPERATION
*/
void onStartFailure(byte Oper, int errorCode);
} /**
* operation mode: advertisement.
*/
static final byte OPER_ADV = 0x00;
/**
* operation mode: connection requirement.
*/
static final byte OPER_CON_REQ = 0x01;
/**
* operation mode: connection response.
*/
static final byte OPER_CON_RSP = 0x02;
/**

*/

/**

*/
static final byte OPER_CLOSE = 0x06; /**

*/
static final byte BLE_ERROR_OK = 0x00;
/**
* Error: At least one of the input parameters is invalid
*/

*/

/**

* time out
*/
static final byte BLE_ERROR_CONNECTION_TIMEOUT = 0x03;
/**
* Error: connection has disconnected
* time out
*/
static final byte BLE_ERROR_CONNECTION_DISCONNECTED = 0x04;- 增加新的方法
/**
* ble advertisement start by special device name
* only simulate method because ble communication session
* support device need equal LE General Discoverable Mode and
* BR/EDR Not Supported.
* @param device_addr : scan device address
* @param response_data : response data
*/
void bleScanResponse(String device_addr, byte[] response_data);
