Help find controller with bluetooth, cheap, widely available

[casainho]

I would like to get suggestions for a ebike controller that have bluetooth, cheap, widely available and that uses a well know microcontroller (preferable STM32) and have well known and popular technology - easy and cheap for repair and modding.

Why I am looking to this? because I want to use a well know controller that it is easy to repair/mod/adapt for my specific projects. I will develop the firmware for it, as OpenSource and I would like to share with others that have the same needs. My mission similar to the Tesla (https://www.tesla.com/blog/mission-tesla): "to accelerate the advent of sustainable transport" and innovation on personal light electric vehicles.

The controller I have as referenced and I modded in past is KU63 that we have a lot of technical documentation (thanks to Albert van Dalen): http://www.avdweb.nl/solar-bike/electronics/ku63-motor-controller.html -- on that time we didn't know the microcontroller nor we had an EN datasheet as we have now.

So now I would like to return to this project and I am look to find a kind of KU63 with simple included serial UART bluetooth. Also with possibility for the firmware to be flashed by the bluetooth, like I know it is done on some controller boards that I am being development firmware (for electric unicycles): https://github.com/EGG-electric-unicycle/documentation/wiki/MicroWorks-30B4-30kmh-controller-board-with-bluetooth

Thanks in advance for the help.

Sorry I can't attest to the component specifications, but this Controller from Yuyang King has bluetooth capability, and is fairly inexpensive:

Thanks!!

Do you have any experience or know any link for review or such for such controllers and YuYangKing?

Goggle shows me this site selling the same controller?? https://lunacycle.com/40-amp-36-72v-ebike-bluetooth-programmable-controller/

Seems there are not much controllers yet with Bluetooth, at least the cheap ones.

You can also hook a bluetooth / serial module to the programming port existing on most regular controllers this is what PowerVelocity does and it works great.

I don't think that's a YYK controller. Looks just like the controller that came with a cyclone kit I bought recently, actually.

Thanks!. I saw the prices of PowerVelocity and they are very expensive.

If we follow that link, the PDF user manual says on top that is a YuYangKing controller. At the same time, the bluetooth device name shown is "Daymak" that seems a name of another company...

Teslanv, would be possible for you to post pictures of the board of your controller? also picture detail of the microcontroller?

Anyone knows a link were I can see inside pictures of YuYangKing / LunaCycle controllers?

Manybe a group buy is the next step. Cassaiho where do you live ?

What I found until now:

- I had an answer from LunaCycle (they were helpful, thanks!!) and seems the bluetooth controller is from YuYangKing
- I got this information about this controller:

Its a yuyangking cheap squarewave one. I imported them for two years and dropped them in the end from my range. A bit of a disaster on the dyno due to dropouts at low eRPM, and the bluetooth is hard to join. Let me find the charts.
For hubs, they are erratic at getting the regen working.

- the controllers like KU63 uses XCM X8M06/μPD78F0714 which there is no datasheet and tools to program it
-- the same for the ST CR8F612X, on the S06S controller

Seems there are some cheap controllers doing sinewave and using STM8S105xx!! I am not sure but I think BMSBattery may have some.
This STM8S105xx is well know, with cheap and OpenSource tools for development and program
On Ebay, we can find development boards with STM8S105xx that costs only $3!!

Info for program: http://www.cnx-software.com/2015/04/13/how-to-program-stm8s-1-board-in-linux/

Anyone can help find a controller that uses STM8S105xx??

By now I already gave up about controllers with bluetooth, seems they are not available yet. But who knows if having controller with our OpenSource firmware we can easily mod to add the bluetooth module??

Portugal. But now interested for now, to buy a controller from YuYangKing.

check out arm bldc controllers. infineon has a new one that looks killer, but they only sell bulk. atmel tools and support rules, ti isnt bad, nxp is brutal and i would avoid

learn eagle and get your own board made by an online pcb fab. its stupid easy these days

its just the mcu and a 3 phase inverter plus some caps and a current sense. dont settle for what you can find thats already been made, start with something wothy of your time.

just my 2 cents...ive put ungodly hours programming chips only to discover another one for $5 more that blows it away

I am not looking to make my own controller.

I selected the cheap wide available S06S/12, etc with the microcontroller STM8S105C6T6. An user documented the protocol between the controller and the LCD and it seems plain UART, so a bluetooth module connected instead of the LCD should be perfect for what I was looking for -- connection to an Android.
