The DA14683 is fantastic. I played a bit with an eval. board and it's really good for it's price vs. features (~$3 for 250 pcs. at Mouser). But soon the idea of releasing code for it as Open Source faded away, since you need to sign an SLA (https://support.dialog-semiconductor.com/connectivity/request-access-restricted-content https://support.dialog-semiconductor.com/connectivity/reques...), that limits the way source code based on their in SDK is released (only to your customer, in an only “need to know” basis). I hate when this happens.
I wonder how the creator of this watch managed to publish the source code, including the Dialog SDK; if there is a backdoor I am missing.
- opencl 8y agoProbably by ignoring the license.
- echlebek 8y agoPretty reasonable way to solve this problem really. Are they really going to bring the hammer down on a hobbyist?
- ISO-morphism 8y agoI share a hatred for this sort of thing that happens all too often the closer you get to hardware, mainly as a byproduct of the culture. However, refusing to adhere to a proprietary license damages respect for all software licenses, especially the GPL, in the global software community. Depending on where you fall on the anarchy vs rule-of-law scale that may or may not be a good thing. Flip side of the argument: "Someone wrote a GPL library I want to use but I don't want to release my source. Is anyone really going to notice, care, or bother to bring the hammer down on my company?"
- Sidnicious 8y agoDoes anyone know how this compares to the nRF5x series (and/or other BLE-friendly microcontrollers)?
- jpablo 8y agoIt does look very similar to the nrf52 line. The nrf52850 even has double the SRAM (256kb).
- undecisive 8y agoAs I understand it, the designer used freertos. At that point, he can just give a readme with hand-wavey "get sdk, install freertos, find firmware files here... and here's all my code which I'm free to license as I wish" and no license infringement necessary. Not sure why a backdoor is needed, but then I've never built a project like this.
- 0xdeadbeefbabe 8y agoHN needs to know; it's a front door.
- gabriel34 8y agoFor open source community projects a better bet than a bespoke case would be aiming for the form factor a a popular watch movement, so that hackers can chose to buy or build a bespoke case.
- scoutt 7y agoRemoved SDK files at request of Dialog Semiconductor https://github.com/S-March/smarchWatch_PUBLIC/commit/12b4ad373873ced0ac3a157dc07d13784deb1409 https://github.com/S-March/smarchWatch_PUBLIC/commit/12b4ad3...
