iOS plus Nimbus Controller

Every now & then while playing Minecraft on my iPad, the controller "glitches" & the camera continuously "pans" in a circular motion. I turn off the Bluetooth on my iPad, reconnect, & then usually it goes away. But lately, I have had to delete & reinstall the game, this keeps the glitch away for about 1/2 an hour. I have reinstalled the nimbus software, returned the controller for diagnosis, & had the remote replaced, & the glitch still continues to appear.
