SmartSpin2k VS esp-nimble-cpp

Edit: maybe this was it? https://github.com/doudar/SmartSpin2k I don't know what your enjoyment for DIY stuff is, but this is doable.

This can automate resistance adjustment - https://github.com/doudar/SmartSpin2k

It’s a device that goes on the knob of a spin bike and turns it into a smart trainer. The project is in its 4th year and 3rd hardware revision. We went from no pcb to a pcb that was a carrier board for dev kits to now a full custom pcb. It works great! https://github.com/doudar/SmartSpin2k

Schwinn IC4 is a good bike. I hear good things about the Echelon Connect Sport as well. Both can be turned into a smart trainer with a bit of DIY effort using a SmartSpin2K to control the resistance dial automatically. It's a fun little addon that improves the experience. Worked brilliantly for me since I've got a very small condo with no space to bring a bike upstairs and onto a trainer. The spin bike was way easier to dedicate the space to 100% of the time and my partner also gets to enjoy it

Check out https://github.com/doudar/SmartSpin2k and add automatic resistance to your spin bike. Everything you need to build your own, or a limited number of pre built kits are available!

If the recumbent has a knob-based resistance control like a spin bike, you can use a SmartSpin2K device: https://github.com/doudar/SmartSpin2k with power meter pedals. (There's also a retail competitor, IDK about patents and such, but I always favor the maker version.)

I like NimBLE-Arduino, and this has a BLE client example that you can adapt to your needs, including both regular reads and notifications. Note that this isn't pure C++, this is using Arduino. There's also a version for use with ESP-IDF: esp-nimble-cpp, with a corresponding BLE client example. The examples for both projects are heavily commented and quite easy to follow.

On the ESP32 side, I use this library: https://github.com/h2zero/esp-nimble-cpp

No idea what “nimble” is but the first result on google for “nimble library” points at a esp thing: https://github.com/h2zero/esp-nimble-cpp

I have a project using NimBLE, and I'm trying to understand limitations / best-case / how to improve BLE latency.

Im working on a mesh project and want to use BLE to have communication between a smartphone and the mesh. I worked with this nimble lib before but i cant use it since compiling the MDF project with nimble enabled fails. Basically i need https://github.com/nkolban/ESP32_BLE_Arduino but for IDF.

Have a look at my project https://github.com/koenvervloesem/M5Core2-Heart-Rate-Display. It's using NimBLE-Arduino, but if you prefer to use ESP-IDF instead of the Arduino framework there's also esp-nimble-cpp with almost exactly the same API.
