Hi,
I have a problem with unmodified BLE Shell and changing security level to 2(aka just works).
1. I'm connecting from BLE Shell to the device that requires level 2
2. After the connection is succesfully established I'm trying to perform `bt security 2`
3. It fails and outputs some strange communicates
Why it mentions `level 1` when I tried to change it to `2`?
The device works great with Android and iOS phones. It also worked some time ago with previous versions of BLE Shell, but it doesn't work on latest ones.
