Re: TSDZ2 mid drive with 860C, 850C or SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

I thought about it but I wasn't sure to implement it, or in a first time only a manual reset. But it's a nice feature and I'll made it configurable (manual and/or auto reset with configurable amount of hours). Good to be able to disable as on some 850C/860C / users, the clock fails. On my ebike tha...

Re: Fully wireless ANT+ BLE TSDZ2 mid drive motor (like Specialized Turbo Levo) -- Flexible OpenSource firmware

4. Would be nice if there was a standard for ebike on Bluetooth, so any mobile app could connect to every ebike. there are profiles we can use: https://www.bluetooth.com/specifications/gatt/ i did not read into them. There are none for ebike. There are only for cycling sensors like cadence. yes, lo...

What can it be?
Disable BOOST and try again. If it solves that issue, then I will disable the BOOST code until someone correct it.

yes, cheap phones will not have the brightest screens. if there is nothing comparable in the 50€ class to the 860c brightess now it may come on some years. there are a lot phones to choose from, so i think everyone will find one that fits his requirements and price range. and for battery - yes even...

Re: Fully wireless ANT+ BLE TSDZ2 mid drive motor (like Specialized Turbo Levo) -- Flexible OpenSource firmware

While it sounds like fun to build our own display, i do not think it is worth the effort. i expect the "cheap" 10€ display to also be cheap quality which manifests in low resolution and readability in direct sunlight. also, while it is cheap on the hardware costs, it requires a lot of work to make ...

What's the easiest way to reset the firmware or configuration as I'm hitting a 220watt limit and I can't find what config is causing it? Or just go back to the latest stable version instead of the 1.0.0 version? Do your work and read the configurations page. The wiki was the first place I went to. ...

Hello Your progress with the bluetooth displays looks great!

Ideas for a DIY switch For the switch, other than try to go with the BLE one, I would like to explore to use an ebike button.

It is always good to have more than one remote bike button to test. If we connect the Remote directly to the Wireless extension, it may work well. If we connect via Garmin edge there may be some delay. But the turbolevo has three systems 1 - Buttons connected with cable 2 - Ant + wireless connectio...

Look at this legs, they are not much bulky and I am pretty sure I don't need that amount of force, I just need maybe 1/4 say they could be even less bulky:
