hey all, I love the excellent source of info you all have compiled here (except for the deleted posts that no longer are cached on google.. that made it a little harder)
Anyways, I wanted to reach out and ask about something. I've successfully found the codes for Firmware, On/off, Lights on/off, flashing light on/off, and speed governor on/off. so I think it's safe to say I'm well on my way (are there any other functions I should look for, or have I found them all?)
My question is - I used these codes to operate both a sj2.5 and a sz2.5, but my 2nd sz2.5 has given me some trouble. The only codes that seem to work are the unlock code (which just takes away the 06e error, but doesn't power it on like the other two), and the flashing light on/off. The rest of the same codes for this particular one doesn't seem to do anything. I've also noticed that the front wheel is hard to turn (the others turn with just a hand spin, this sz2.5 seems to need more force to turn the wheel), and in googling around I've noticed two things:
1. many forum posts suggest that the motor controller is dead, either due to abuse or steep inclines
2. there was a number of articles last year that suggested that it was also caused by a faulty firmware applied to the scooters.
my question is - if it's a faulty firmware, does that mean it never was the motor controller and can somehow be overridden/fixed without replacing parts?
Also, even tho I've found all of the codes, I'd love to reverse engineer the FW to figure out exactly how those code were produced/found/read and I haven't been able to find any guides that walks me thru the correct settings in RealTerm or any similar program to get going in the right direction.
I know you all are extra careful about the information you let stay in this forum, but if someone could answer my questions and point me in the right direction for settings/reverse engineering the firmware, that would be super helpful!
I haven't replaced any parts, I've only used the power controller already included and a bluetooth hc-05/hc-08 for communication. Thanks for all the help!!
