Using the provided example, when I tap on a device, go to the device details page and tap return button to go back to device list like 3 times it craches, without doing anything on the details screen, it crashes and then scan does not work anymore. Here is the verbose code:

Thanks for reporting it! Example needs a proper rewrite - it seems BLE client is created every time the scan screen is entered.
