【问题标题】:The BLE advertisement package getting frequency become very lowBLE广告包获取频率变得非常低
【发布时间】:2016-09-07 03:54:56
【问题描述】:
我的项目需要接收 BLE 广告包,并在不连接 BLE 设备的情况下处理 kCBAdvDataManufacturerData。BLE 设备每秒发送 1 次广告包。在空视图控制器中,我每秒接收 1 次广告包,但在我的我显示 BLE 广告包数据的控制器,我接收广告包的频率减少到 1 次/4 秒或更低。在这个控制器中,我发送一些 http 请求并使用 NSTimer 更新 UI 每秒 1 次。我在 dispatch_sync 中处理 kCBAdvDataManufacturerData (dispatch_get_global_queue(0, 0),并在 mainqueue 中更新 UI。
有没有人想提高接收BLE广告包的频率?

【解决方案1】:
-1。首先你需要开始发现。
-(void)startDiscovery
{
if (self.mBtmanager == nil) {
_mScanState = false;
self.mBtmanager = [[CBCentralManager alloc] initWithDelegate:self queue:nil];
self.mBtmanager.delegate = self;
}
if (self.mBtmanager.state != CBCentralManagerStatePoweredOn) {
_mScanState = true;
}
NSDictionary *scanOption = @{CBCentralManagerScanOptionAllowDuplicatesKey:@YES};
[self.mBtmanager scanForPeripheralsWithServices:[[NSArray alloc] initWithObjects:[CBUUID UUIDWithString:JAALEE_ADV_SERVICE_UUID_STRING], nil] options:scanOption];
}
- 2. 你需要连接到 Beacon。
-(void)startConnectDevice:(CBPeripheral*)peripheral
{
peripheral.delegate = self;
[self.mBtmanager connectPeripheral:peripheral options:nil];
}
-3。然后使用 writeServicesUUID 更改广播间隔
[peripheral writeValue:value forCharacteristic:characteristic type:CBCharacteristicWriteWithResponse];
-最后 CONFIGURE_BROADCAST_INTERVAL_CHARACTERISTIC_ 会帮助你。
