连接蓝牙

bleLinkUtil.linkDevice(bluetoothDevice.getAddress(), new OnBLEFindServiceListener() {
            @Override
            public void onLink(boolean isSuccess, final List<BluetoothGattService> services) {
                bleLinkUtil.setUUID(MSConstant.COM_SERVICE_UUID, MSConstant.TX_CHAR_UUID);
                MSLogUtil.e("连接成功");
            }
        });

接收通知

bleLinkUtil.startGetNotification(MSConstant.COM_SERVICE_UUID.toString(), MSConstant.RX_CHAR_UUID.toString(), new OnBLENotificationListener() {
            @Override
            public void onGetData(String data) {
                MSLogUtil.e("onReadMessage: " + data);
                if (data.contains("CONFIG_SUCCESS")){


                }

            }
        });

发送消息

private void sendConfigWifiCmd() {
        String wifiSsid = btn_wifi_name.getText().toString();
        String wifiPwd = et_wifi_pwd.getText().toString();
        String serverIp = btn_server_ip.getText().toString();
        String serverPort = et_server_port.getText().toString();
        JSONObject cmdJson = new JSONObject();
        cmdJson.put("cmd", "wifi_config");
        cmdJson.put("wifiSsid", wifiSsid);
        cmdJson.put("wifiPwd", wifiPwd);
        cmdJson.put("serverIp", serverIp);
        cmdJson.put("serverPort", serverPort);
        bleLinkUtil.write(cmdJson.toJSONString(), new OnBLEWriteListener() {
            @Override
            public boolean onWrite(boolean isSuccess, String readStr) {
                Log.e(">>>", "onWrite: " + readStr);
                if (isSuccess) {
                    MSLogUtil.e("发送成功");
                } else {
                    MSLogUtil.e("发送失败");
                }
                return true;
            }
        });
