哪里是例如iOS的蓝牙LE peripheralManager didReceiveWriteRequests的

问题描述

限时删除！！

我需要的功能didReceiveWriteRequests的示例实现其在运行iOS的蓝牙数据时由中央iOS设备做了写它周围'writeValue：

I need an example implementation of function didReceiveWriteRequests which runs at a Bluetooth iOS peripheral when data is written to it by the central iOS device doing a 'writeValue:' .

不过，我搜索网页，并不能找到例子。苹果文档仍然没有样品code。

But I've searched web and cannot find example. Apple docs still have no sample code.

推荐答案

我得到了它的工作。这是我的工作code：

I got it working. Here is my working code:

// Processes write command received from a central.
- (void)peripheralManager:(CBPeripheralManager *)peripheral didReceiveWriteRequests:(NSArray *)requests
{

    CBATTRequest*       request = [requests  objectAtIndex: 0];
    NSData*             request_data = request.value;
    CBCharacteristic*   write_char = request.characteristic;
    //CBCentral*            write_central = request.central;
    //NSUInteger            multi_message_offset = request.offset;

    // Face commands this PWR RX to advertise serno UUID?
    int total_write_requests = 0;
    if([ write_char.UUID isEqual: [CBUUID UUIDWithString: YOUR_CHARACTERISTIC_UUID]] )
    {


        // Read desired new_state data from central:
        unsigned char* new_state = (unsigned char*)[request_data   bytes];
        my_new_state = new_state[0];
        #endif
        NSLog(@"        - advertise serno UUID: %s", my_new_state ? "TRUE" : "FALSE" );

        // Select UUID that includes serno of PWR RX, for advertisements:

        ++total_write_requests;
    }

    if( total_write_requests )
        [peripheral respondToRequest:request    withResult:CBATTErrorSuccess];  // result = success
    else
    {
        NSLog(@"_no_write_request_FAULT !!");
    }
}
