I have a question about using BLE with the iOS Simulator.

I followed these instructions to set up XCode simulator with BLE: http://developer.apple.com/library/ios/#technotes/tn2295/_index.html

I use a Mac os 11.6 big sur and Xcode 12.5 on VMware Machine with built-in BLE and a CSR USB BLE Dongle. Mac OS X discovers the USB Dongle, because it is shown in the System Information.

After that I enter this command:

sudo nvram bluetoothHostControllerSwitchBehavior="never"

to have the Broadcom chip again and Bluetooth configuration does not appear in the ios emulator settings app and is not available.

So what the problem here?

Thanks for help!

Bluetooth info, Simulator Setting App

Unfortunately, the problem is that technote is ancient.

BLE support was dropped from the simulator in iOS 7

You need to use a real device to debug Core Bluetooth iOS applications.

Core Bluetooth does have a consistent API between iOS and macOS so you may be able to trysome code in a Mac app and then transfer it to your iOS app, but for the final test you will need to use an iOS device.
