当我当时加载任何方法时,它会向我显示此警告,因为我正在使用从方法中检索的特性

var cbChar :  CBCharacteristic
func bleManagerPeripheral(_ peripheral: CBPeripheral!, didUpdateValueFor characteristic: CBCharacteristic!, error: Error!) {
cbChar = characteristic
}

当我尝试写下一行时收到警告

[self.cb  writeValue:aData forCharacteristic:cbChar type:1];

我正在变暖

[CoreBluetooth] WARNING: Characteristic , notifying = NO> does not specify the "Write Without Response" property - ignoring response-less write

谁能帮帮我?

最佳答案

您正在写入的特性不支持无响应写入,但是当您调用 writeData 时,您正在为 type 参数传递 1 . 1 对应于 CBCharacteristicWriteWithoutResponse。该警告告诉您 Core Bluetooth 无法执行您要求的操作。

您需要指定CBCharacteristicWriteWithResponse

[self.cb  writeValue:aData forCharacteristic:cbChar type: CBCharacteristicWriteWithResponse];

关于iOS- BLE <CBCharacteristic : does not specify the "Write Without Response" property - ignoring response-less write,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/50833048/
