I put in a 30s delay on boot to give me more time to pair, see the instructions here https://www.petrockblock.com/forums/topic/ps3-bluetooth-controller-correct-method-for-retropie-2-3/. (look at comments 84419 and 84681)

It would be ideal if you could connect anytime though, and I still have issues where sometimes only one controller will connect at a time.
