大佬教程收集整理的这篇文章主要介绍了iphone – iOS蓝牙LE peripheralManager didReceiveWriteRequests的例子，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

概述

我需要一个函数didReceiveWriterequests的示例实现,当中央iOS设备写入’writeValue：’时,它会在蓝牙iOS外设上运行. 但我搜索网络,找不到例子. Apple文档仍然没有示例代码. 我搞定了.这是我的工作代码： // Processes write command received from a central. - (void)peripheralManager:

@H_674_18@ 我需要一个函数didReceiveWriterequests的示例实现,当中央iOS设备写入’writeValue：’时,它会在蓝牙iOS外设上运行.

但我搜索网络,找不到例子. Apple文档仍然没有示例代码.

解决方法@H_@R_489_11263@_24@

我搞定了.这是我的工作代码：

// 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 @R_686_10586@l_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:

        ++@R_686_10586@l_write_requests;
    }

    if( @R_686_10586@l_write_requests )
        [peripheral respondTorequest:request    withResult:CBATTErrorsuccess];  // result = success
    else
    {
        NSLog(@"_no_write_request_FAULT !!");
    }
}
