Getting a Mac to connect to the Perdix AI is sadly painful. I’ve made it work several times, but I cannot give you a reliable algorithm.
If you keep trying to scan from within Subsurface at some point you’ll see the Perdix AI. One thing that our friends at Shearwater recommended was to only let the Perdix AI run in Bluetooth mode for about 20 seconds. If by then the scan hasn’t found it, cancel and start Bluetooth mode again. So you have two things running that will both time out or need to be restarted: the scan on the Mac and the Bluetooth mode on the Perdix. I realize that that’s just weird, but believe me, several of the developers have tried to come up with a more reliable way to do this and we haven’t been successful. But all of us have eventually been able to connect using the “algorithm” described here.
If this really doesn’t work for you, there are a couple of ways to trick Subsurface-mobile into downloading ‘more’ dives (but the problem is that we’d want to make sure that we don’t lose any data that you have manually entered for the successfully downloaded dives). So the easier solution would be to try the above.
Finally, after thinking about this some more I’m thinking that maybe we could add a couple more options to the download dialog and hide them by default and create a “magic trick” to enable them - maybe if developer mode is enabled in the Settings or something. This is NOT something that exists today and I haven’t looked into how much work it would be to implement it, but it shouldn’t be too hard.
