Description

Add Bluethoot FTMS support to read and control an treadmill.
Software project is here https://github.com/lefty01/ESP32_TTGO_FTMS

 

Most of this project was done by Andreas Löffler and he deservs all the cudos :)

 

This is still in the dev stage but usable the idea is to connect the REED signal to the treadmill wheel sensore, or some other way of meassure distance. Then speed and distance can be calculated. You can have a accelorometer to measure the inclinde and depending on where you place the module you can have an onboard or off board. If you connected it to the buttons on your treadmill you can controll speed and incline by simulating buttonpresses.
First set of scematics aim as a usable dev platform e.g. will hopefully work but have a lot of nice stuff to debug. The dev board aim to support TTGO T-Display, TTGO T-4 and WT32-SC01 with the same board, but you can only connect one of them.
