我得到了蓝牙低能量心速监测仪 使用蓝牙核心图5.0的框架。但有时我遇到以下的问题。
1) 有时当我开始扫描(使用 scanForPerifferals with Services 方法)时,它无法发现任何 BLE(蓝牙低能) 设备, 直到我关掉并手动打开 Iphone Bluotos 。 如果蓝牙关闭并打开不起作用, 我不得不重新启用手机 。
2) 有时,当我试图连接我先前存储 UUID 的设备时,我能够连接到设备,即 没有ConnectPeperpheral 代表法被调用,但是它从未发现任何服务,尽管我叫[外围发现服务:nil] ,即我无法从代表法 Discover Services 中从设备获取任何数据。为此我不得不重新启用电话。

1) It has something to do with the pairing routine on bluetooth low energy and the iPhone. The iPhone changes its ID every interval, I don t know how often, but it does. Have you tried just resetting/rebooting the slave device? This often works for me. The slave device also has a limited broadcast period, e.g 20-30 seconds.
2) Again, check that you have reset the slave. I don t know if you have built the device your self or bought a heart rate belt, but this is most often the solution.
Oh and by the way, I had an issue where the didDiscoverServices actually jumped over an if-sentence, where I checked for a specific service. This did not fix it self until I rebooted the phone. Really weird behaviour, but I haven t found any other solution to this yet.
