We need a way to force the establishment of a connection so that multiple products can connect to the scanner gun smoothly.

Hello!
Currently, we have encountered such a problem:
When multiple products are installed on the Nordic gun, if app_dev is already connected, then app_fat cannot be connected no matter how many attempts are made. Moreover, this problem also exists in the programs built into the Nordic gun. That is to say, once the demo on the Nordic gun is opened and connected by the user, we will not be able to connect through our own app. I have searched the relevant materials, but I haven't found any documents that can deal with this problem, and I haven't found the relevant implementation in the code either.
In addition, I would like to ask whether you have more detailed Android development documents?
Thank you for your attention and help!
