Bluetooth devices disconnecting from iPad

Since the upgrade to iPadOS 16.1-16.2, my iPad will randomly disconnect from my Bluetooth devices. I use a Nimbus+ controller, Bose QC45 Headphones, and play COD Mobile. I will turn on both devices; they will indicate that they are connected (and show connected in settings & in the COD settings). Just as I enter the game from the "waiting room," my Nimbus often disconnects, and I either have to swipe up, go to the iPad settings and reconnect or exit COD entirely. It also happens after I have successfully started a game and am into it for a while, and then "boom," the controller stops responding and starts indicating that it is looking for the connection. I have to swipe up, go to settings, reconnect and hope I haven't lost while I was "gone." The same thing will happen with the headphones working fine, the "disconnected" message in my ears. It also happens (more rarely) with my Logitech keyboard. Sometimes 1 of the three, two of them, or all three at once. At first, I thought it was the game, but it happened with the headphones on Netflix, & YouTube and the Keyboard whilst typing.

I am running a 1-year-old iPad 12.9 Pro with 200 GB of 256 free. The Controller and Headphones are about 3 months old and have been updated per Bose & SteelSeries instructions. I have forgotten the devices and reinstalled, deleted, and reinstalled the game. All of the "standard" fixes in the forum and Google. None of this occurred (that I recall) prior to iPadOS 16.

Any help would be appreciated.
