在iOS7.1.1上,以下BLE操作成功 - 它假设我有一个BLE连接设置等...
[[self peripheral]writeValue:dataToWrite forCharacteristic:nextCharacteristic type:CBCharacteristicWriteWithResponse];
但如果我切换"类型" CBCharacteristicWriteWithoutResponse,我得到以下警告,外围设备没有收到命令:(
[[self peripheral]writeValue:dataToWrite forCharacteristic:nextCharacteristic type:CBCharacteristicWriteWithoutResponse];
错误:
CoreBluetooth[WARNING] Characteristic <CBCharacteristic: 0x178081f90 UUID = 249C2001-00D7-4D91-AC75-22D57AE2FFB8, Value = (null), Properties = 0x28, Notifying = YES, Broadcasting = NO> does not specify the "Write Without Response" property - ignoring response-less write**
任何线索都赞赏!
