连接到设备后，BLE中多次写入命令 [英] Multiple times of Write command in BLE after connecting to device

问题描述

大家好，目前我在BLE工作。

我已连接到设备。读命令和写命令工作正常。

我的问题是什么...



连接后我可以一次又一次地发送写命令到了设备。

Hi all, currently i'm working in BLE.
I have connected to the device. Read command and write command works fine.
What My question is...

Can I send the write command again and again after connected to the device.

推荐答案

啊最后我得到了解决方案。感谢所有帮助过我的人。这是解决方案。现在我可以把这个写mtd称为任何地方&任何次数。

Ah finally i got the solution. Thanks for everyone who helped me. Here is the solution. Now i can call this write mtd anywhere & any number of times.

CBCharacteristic *Writechar = nil;
CBPeripheral *writePeri = nil;

-(void)peripheral:(CBPeripheral *)peripheral
didDiscoverCharacteristicsForService:(CBService *)service
error:(NSError *)error
{
    for (CBCharacteristic *characteristic in service.characteristics)
    {
            [peripheral readValueForCharacteristic:characteristic];
            [peripheral setNotifyValue:YES forCharacteristic:characteristic];
           if ([characteristic.UUID isEqual:[CBUUID UUIDWithString:@"ABCD"]])
           {
                    Writechar = (CBCharacteristic*)characteristic.UUID;
                    writePeri = (CBPeripheral*)peripheral;
                    [writePeri readValueForCharacteristic:characteristic];
                    [writePeri setNotifyValue:YES forCharacteristic:characteristic];
           }
    }
}



- (void) write
{
for(CBService *service in writePeri.services)
    {
        for (CBCharacteristic *characteristic in service.characteristics) {
            [writePeri readValueForCharacteristic:characteristic];
            [writePeri setNotifyValue:YES forCharacteristic:characteristic];
            if ([characteristic.UUID isEqual:[CBUUID UUIDWithString:@"ABCD"]]) 
            {
                     [writePeri writeValue:data forCharacteristic:characteristic type:CBCharacteristicWriteWithResponse];
            }
         }
   }
}
