Hoping for a handful of magic beans here....
I have an iwatch here on the desk that I have been asked about designing a gadget for. Ther was back in 2015 quite the buzz about this "secret port" apple put on the watch with one intrepid person/group making a new strap for the watch that had a battery in it that supposedly charged the watch faster than the inductive method:
I have also read blogs that Apple promptly did a software update that rendered this no longer possible.
After a lot of Yahoo-ing, and Google-ing with limited success I am still in search of the pinouts for this port. I can get a probe that apparently the cell phone stores use to do things to the watch at the store through the 'secret port', but I was hoping that the pinouts would be available by now as the "Port Reports" have been around since 2015.
Has anyone managed to find anything on this port?
