ios phone can not reconnect device

HI,all In normal circumstances, ios phone paired and connected to my 52832 device, when they are disconnected, ios phone can automatically reconnect the ble device. But sometimes they are disconnected, ios phone can not be automatically reconnected, What's wrong with this?

i used the smart remote 3 example,sdk 12.2。 thanks!

  • nowhere near enough information to even hazard a guess. You need to post some analysis of what you've tried, event sequence, some code if you've changed it. Just saying 'phone can't pair' says nothing.

  • I can pair and bind my device. After binding, when the connection is disconnected, the phone can automatically reconnect to the device. But sometimes the phone automatically reconnect will fail, I need to manually reconnect.

  • So if you really care about the solution you need to debug on link layer, typically with RF analyzer/sniffer.

  • @zwf: Consider checking the iphone device log in xcode (if you have access to that). I have seen something like this a few years ago, where the peripheral was "black listed" i.e. iOS stopped reconnecting automatically when the device disconnected/reconnected multiple times in a row. Could possible happen if the device is on the range limit (I think this was with iOS 8).
