。我正在研究使用核心藍牙框架的應用程序.App與啓動，鎖定，解鎖門有關。藉助Apple提供的示例，我幾乎可以完成應用程序。那就是心率監測器和溫度傳感器。將數據發送至Core Bluetooth Framework Xcode
我有2個問題。 1：心率監測器應用程序從外設讀取數據，而在我的情況下，我只需要發信號通知startButton被按下的外設。所以我的問題是，我是否需要在discoverCharacteristics方法中使用writeValueForCharacteristic。
2：如果是這樣好心幫我在這裏按鈕代碼
- (IBAction) startButtonPressed: (id) sender {
}
- (IBAction) lockDoors: (id) sender {
}
- (IBAction) unLockDoors: (id) sender {
}
代碼由下式給出。
- (void) peripheral:(CBPeripheral *) peripheral didDiscoverServices:(NSError *)error
{
if (error)
{
NSLog(@"Discovered services for %@ with error: %@", peripheral.name, [error localizedDescription]);
return;
}
for (CBService * service in peripheral.services)
{
NSLog(@"Service found with UUID: %@", service.UUID);
if([service.UUID isEqual:[CBUUID UUIDWithString:@"1809"]])
{
/* Car Start Service - discover
