Reducing connection time when configured as a BLE 5 peripheral to an iOS devicehttps://devzone.nordicsemi.com/f/nordic-q-a/74197/reducing-connection-time-when-configured-as-a-ble-5-peripheral-to-an-ios-deviceWe have a prototype device that disconnects and reconnects frequently. When moving from a BLE 4.2 chip to the nrf52840 (BLE 5), we noticed that the time to complete the initial connection went from about 300ms on the iOS side to about 800ms.
