Answer 1

您需要发布代码才能获得帮助。 首先查找您的设备 - 代码是 obj c，但您应该可以轻松地进行相应更改以实现快速

  if (central.state == CBCentralManagerStatePoweredOn) {
    [_centralManager scanForPeripheralsWithServices:@[[CBUUID UUIDWithString:@"0x180A"]] options:@{CBCentralManagerScanOptionAllowDuplicatesKey : @YES}];
    NSLog(@"Start scanning");
}

如果成功，则寻找这样的特征

 - (void)centralManager:(CBCentralManager *)central didDiscoverPeripheral:(CBPeripheral *)peripheral advertisementData:(NSDictionary *)advertisementData RSSI:(NSNumber *)RSSI {

for (CBService *service in peripheral.services) {
    NSLog(@"Discovered service1: %@", service.UUID);
    [peripheral discoverCharacteristics:nil forService:service];
}
if (_discoveredPeripheral != peripheral) {
    // Save a local copy of the peripheral, so CoreBluetooth doesn't get rid of it
    _discoveredPeripheral = peripheral;

    // And connect
    NSLog(@"Connecting to peripheral %@", peripheral);
    [_centralManager connectPeripheral:peripheral options:nil];
}
}

一旦连接，您将获得特征
