CBCharacteristicWriteWithoutResponse怎么操作

[kanshenmekan]

老哥，[_bleManager writeDataWithPeripheral:self.peripheral serviceUUID:@"0xFFE0" writeUUID:@"0xFFE1" data:D callback:nil]; 传nil好像不管用 看到代码这里选择TYPE CBCharacteristicWriteType writeType = callback ? CBCharacteristicWriteWithResponse : CBCharacteristicWriteWithoutResponse ;

好像只要执行writeDataWithPeripheral，就会调用[character writeValueWithData:data callback:^(EasyCharacteristic *characteristic, NSData *data, NSError *error) ，这个callback不可能为nil啊，判断只能是CBCharacteristicWriteWithResponse
