I've been working on a DIY watch off and on a bit. One of the bigger obstacles for me personally has been bluetooth notifications. I have found surprisingly few examples online of people getting it to actually work, and if you read through their work more closely, it only very barely works. I've tried to reproduce what other people have done and had it actually work even less than that. I was thinking of selling a pre-programmed bluetooth module with apple and android notifications etc. if I ever got it working, figuring there must be other people in the same situation with this pain point. So far the idea that I could do a better job than others that have tried has turned out to be hubristic, though.
