Source code here: https://github.com/jtwaleson/cowboy-bike-remote-ble https://github.com/jtwaleson/cowboy-bike-remote-ble I’m currently working on finalizing the PCB version, the first one had some flaws so the battery drained really quickly.
- spaboleo 4y agoThank you. I just recently discovered the nRF52 as a potential solution for my own BLE project. To use a keyfob as a housing is brilliant and very 'stealth'. I have no experience with the nRF52 chips, but this will be a very useful resource for me. In your blog post you mention that "switching between 24km/h and 25km/h" is very important. May I ask why? Isn't such a speed difference almost negligible as you easily surpass it when pedalling?
- jtwaleson 4y agoIf you ever get stuck don't hesitate to reach out :) There is EU regulation to limit the bike to 25km/h. If you look at the code you can see how the switching between 24 and 25 km/h works. The rest I leave as an exercise to the reader.
