writeBLECharacteristicValue:fail

调试蓝牙功能发送函数出现错误：{"errMsg":"writeBLECharacteristicValue:fail","errCode":10013}
跟踪调试后发现value值为空值。

暂时解决方式：把uni.writeBLECharacteristicValue替换为plus.bluetooth.writeBLECharacteristicValue
plus.bluetooth.writeBLECharacteristicValue({
deviceId: deviceId,
serviceId:serviceId,
characteristicId:characteristicId,
value: new Uint8Array([0, 0, 0]).buffer,

              success: res => {  
                console.log(JSON.stringify(res));  

              },  
              fail: res => {  
                console.log(JSON.stringify(res));  
              }  

            });
