我使用以下代码连接到蓝牙心率传感器。在iOS8和设置下连接的蓝牙设备之前,这一功能正常。当我按“忘记此设备”时,我的代码再次运行。如何修改代码以连接“连接心率传感器?”
//请求CBCentralManager使用服务UUID 0x180D扫描心率外设 - (void)startScan {
[self.manager scanForPeripheralsWithServices:[NSArray arrayWithObject:[CBUUID UUIDWithString:@"180D"]]
options:nil];
for (CBPeripheral *peripheral in self.heartRateMonitors) {
if (peripheral.state == CBPeripheralStateConnected) {
NSUInteger serviceIdx = [peripheral.services indexOfObjectPassingTest:^BOOL(CBService *obj, NSUInteger idx, BOOL *stop) {
return [obj.UUID isEqual:@"180D"];
}];
if (serviceIdx == NSNotFound) {
[peripheral discoverServices:@[@"180D"]];
continue;
}
// have we discoverd the Heart Rate Measurement Characteristic?
CBService *service = peripheral.services[serviceIdx];
NSUInteger charIdx = [service.characteristics indexOfObjectPassingTest:^BOOL(CBCharacteristic *obj, NSUInteger idx, BOOL *stop) {
return [obj.UUID isEqual:@"180D"];
}];
if (charIdx == NSNotFound) {
[peripheral discoverCharacteristics:@[@"180D"] forService:service];
continue;
}
// Are we subscribed?
CBCharacteristic *characteristic = service.characteristics[charIdx];
if (!characteristic.isNotifying) {
[peripheral setNotifyValue:YES forCharacteristic:characteristic];
}
}
}
}
