Good work! Thanks for all your efforts to unravel these things, I really appreciate it. It makes it easier to understand how the world is changing and removes a lot of the fear and uncertainty when you know how a thing works and what you can do with it. Interesting that it's unlocked and unsigned, but I expect its life will be quite limited by the battery's life span. Not so sustainable :(
@atc1441 are you intending to create some firmware/ what would the steps be (bootloader?) to create bespoke firmware to replicate/ extend the healthcare functions that are provided out of the box?
Awesome work, mate! Mine are on the way, looking forward to try out a custom firmware. Counting time to get my hands on it and try something out. Have you found by any chance a repo or source for the stock firmware that comes with the ring?
Hello!nice work as usual! i'm in the way to buy it but i've just a small question,did you know what diffs with the R06? my second question is what can be updated within the firmware to make it better? Greets!
I had this exact question when I first learned about these this morning. From looking at Colmi's website, the battery is the only spec that really seems to change between the R02, R03, and the R06. The R06 has a bigger battery at the larger sizes (sizes 10 and larger get 18mAh) and a smaller battery at the smaller sizes (sizes 8 and 9 get 15mAh). It also has a fancier external metal design. The R03 has the smallest battery (15mAh), but I think that was done to make it thinner as it's the only model showing a bump out in the epoxy for the HRM/SpO2 sensors. It also comes with a USB-C battery charging case which I prefer over the small USB cable that comes with the R02 and R06. The R02's only stand out feature is having the same 17Ah battery on the smallest size rings as well as the bigger ones. There might be more differences, but I haven't found them. As for your second question about making them better, they seem to be about as optimized as possible for what they're intended for. Aaron mentioned in his last video that he might want to expand and intercept the gestures that use the accelerometer to control smart home stuff, but that'd be something personal, not exactly something "better". If you want to use it as a fitness wearable, it's got sane defaults and apparently some options for heart rate monitoring frequency. Maybe you'd want to add more options? Not necessarily "better", but perhaps better suited to you. He mentioned in the last video what hardware was included in the ring, so anything you can envision that works with that hardware should be possible, but using it for gestures probably makes the most sense as practical things you can do with the available hardware.
