RE: How to maintain the stable connection always, foreground as well as background

Hello,

You can try to use background execution modes.

Select your Target -> Signin & Capabilities -> + Capability.

Add background modes and enable "Use Bluetooth LE accessories".

Hello,

Unfortunately, we don't have much experience with background mode, yet. So far, mobile apps by Nordic just work in the foreground only. We're not aware of any possible crashes coming from the system. Which iOS version are you testing on?

However, based on purely theoretical knowledge, the connection should be stable. There are few restrictions, like that an app in the fg when scanning has to scan for at least one UUID, or that CBCentralManagerScanOptionAllowDuplicatesKey is ignored and defaults to false, but I'm sure you already know all of that. Connecting to a previously scanned device, or to a scanned one, should work fine.

We are planning to add an app demonstrating background operations, but this needs to wait. For now, I would recommend checking StackOverflow. Sorry that I can't help more.
