I guess that the 2-minutes turnoff problem is based on an update to the iot-system because there are many people who did not have any of these problems with older scooters (older software). Maybe the rental companies made an update to the es200 scooters which cause this problem. It could be something like a roundrobin-code or something similar.

maybe thats why the kit i bought from batteryprovider isnt working and they arent responded to my emails for assistance lol

Pretty sure you need ground (GND) connected as well, and RXD (yellow) isn't necessary to activate the scooter. (Maybe it can be used in som way to get updates on battery charge and that type of stuff. But than you need to decode the bytes sent to the IOT-box from the scooter.)

It didnt' worked on the Voiager 2 ES100 (mostly equal to the Tier ES200)... I dont know why...
Maybe the code, maybe the my wiring, or maybe an IoT update.
Does somebody has any idea?

Hello guys,

can someone please check-out my project and help me?

1. Can you please check out my esp code, because I'm not sure if it's correct. I want to try varios "Start Bytes" with one try.

2. Can you please check out my wiring, is it correct?

3. I could not find the right screwdriver for the black box (voi voiager2) so I drilled it out. Which screwdriver do I need to open it up without destroying it?

Thank you guys!

Thank you for your fast answer! I will try with GND connected!
I knew about the password line, I put the // there because after I compiled the code, I got a Warning. That is why I thought it’s not working for me. But after I compiled and transferred it to the ESP32 it worked.
Thank you for the help, I will report if it worked out.

Be shure to check voltages on all pins.
Double check which one is 36v, so you don't mess with that one if not absolutely necessary :roll:

:!: And don't trust any pinout and colors mentioned, do your own measurements both once, twice and so on to be sure...

I got super confused when I used the cable from a IOT-box from ES400 TIER scooter to connect Arduino to VOI with help of VOI guide, blue and yellow wire replaced each other in that cable. :?
I was lucky it wasn't weird stuff on the other pin's and that I didn't fry anything. :oops: :mrgreen:

Be totally sure it is an OKAI ES100/200/VOIAGER 2 you're experimenting with. Then it should be relatively safe, but if it's something else then it can be CAN and other weird stuff on the pins easily capable of frying your ESP32 in a heartbeat. :roll: :ugeek:

Been making lots of boxes lately but have not had much luck with the local birds, only jumps. Been using terminal blocks for easier repair when the iny little wires fatigue and fail. Also replaced some of the cheaper red push button witches with solid toggles and better metal screw terminal push buttons. Lots of hot glue now to secure the julet cable.

I have a strange issue I could use your help on. A while back I had 6 Jump scooters. Two of them started showing a weird issue where the speed would jump up randomly, especially going down hill. It would quickly shoot up by 15-20mph and then return to normal every 8-10 seconds. Going down a hill it the speed on dashboard would show 18mph then 28mph then 18mph, 22mph then 46mph.

I basically ignored it Because it was only annoying but on flat ground if the motor speed jumped, the motor would cut out for a half second until it calibrated.

Sometimes, switching off and then on again would buy me 5-20 minutes of no issues before it would start happening.

Well, the first and second scooter I experienced this issue on have now both shut off completely. They will not turn on or display a charge on dashboard. One has wheel lock engaged, the other does not.

I took one apart to about 40% last night and tried disconnecting battery, motor, dash, etc. trying to reset a connection, clear a fault etc. No luck.

Couldn't get the motor off the fork and find the leads but I suspect there is some kind of hall sensor in the wheel that has gone wacky and cant accurately report the speed, as a result the motor has shut down the controller. I was going down a steep hill on one before it happened and suppose that regen could have been over extended and fried something. Both still seem to take a charge when connected but no activities on dashboard to reflect that.
