Thank you very much for sharing this information. I used a baud rate of 9600 because with a baud rate of 11520 the engines stopped from time to time for a very short time.
I need help. i was able to upload the firmware to the motherboard and upload the Arduino software to esp32. im receiving data from the nunchuck and from the motherboard but the wheels are not moving. i tried 6 motherboards and the wheels dont move
Hi I have a question, I have the softwear uploaded to the hoverboard motherboard and to the esp32 my problem is when I have the wheels running it would then violently jerk..help plz.
Wow, wow and once more WOW! I thought your last video was the most detailed but this one just smashed everything else that relates to this topic :-) You did an amazing job. I cannot thank you enough! By the way, have you tested the max range when using ESPNow? Does it reach 400-500 meters?
Thank you for your super kind words :) The ESPnow connection is around the same range as wifi maybe a little bit more, but that is tested with the onboard pcb antennas. Maybe external antennas get bedder range. The reconnection speed is super fast and because it is an onboard fetaure is the reason that i used ESPnow.

Hi, very nice project. On my board I would like to change only the tilt value of the gyro sensor. I want start hoverboard with smaller tilt. Don't know how to do it? Thank you
Could you please share or write a simple test script? Ive flashed the same firmware, but I would like to run it with just a hardwired joystick without two ESP's. Its driving me mad Ive been doing this for 3 days searching everywhere and cant find any code at all to get anything to move
I did it! Although why is mine so jerky do you have any idea? And it also breaks instantly and accelerates instantly. Do you have any idea how to change that?
I solved the build problem by uploading the batch directory to the root directory of the drive. A new problem has arisen. When compiling it shows: "Implicit declaration of function 'sprintf'. This problem occurs in many places.
