我们可以使用蓝牙重新连接断开的外围设备而无需再次扫描ios

Question

I am making communication between ios device and hardware. If my iOS app and hardware are connected using BLE and connection was established. If hardware is out of range or connection got any issue then iOS app will recheck for available devices automatically and if iOS app got previously paired hardware device then will try to reconnect automatically. What should i do to perform such task. I have gone through many links where they are describing to call did retrieve connected peripherals method but by calling this method will it get connected automatically?

Answer 1

Yes, you can reconnect a disconnected peripheral by queuing up a connect command to that peripheral. It will persist until your app connect to the peripheral, at which point the didConnectPeripheral will be called. No scan necessary.
