hi guys, I m using a XLD 350w controller + S866 LCD, everything is working (LCD, brake etc,, wheel is spinning in test mode) but it s not working when using the throttle, any idea ? I checked again the wires and they are all connected
U need a aftermarket throttle I use the blue one with a key & lcd volt screen
I thought that it was just the LCD + controller to change :(

Hello everybody, I have a Ninebot ES3 i bought it from a police aution and I need to unlock it and remove the GPS to make it personal use. Where can I see some steps to do it? Is it easy?

Thanks
Вам нужно обратится в полицию чтобы полиция разблокировала украденный самокат .
Это в Америке полиция продаёт прокатные самокаты или где ?

English Translation:
You need to contact the police so that the police unlock the stolen scooter.
Is it in America the police sells scooters or where?

Hello everyone,

I recently buy a "Lime" and I would like what I needed to make it usable?


Here is a picture of the model I own:

I also attach the photos of once dismounted.

In addition I have a cable that is cut, it goes into the gallows, I wanted to know what this cable is used and it is important ?

Thank you in advance for your answers and your help.
Hi I'm also interested, did you find a way?
У этой батареи нет круглого штекера и uart протокола . На фото Вы вводите людей в заблуждение.

Кроме того . На дисплее затёртая микросхема , но похоже что это драйвер дисплея , а у батареи нет uart протокола .
Таким образом , контроллер-драйвер колеса (там не stm32f103 ) , вероятно получает статус батареи из коробки с GPS and GSM модулем.
Во любом случае это замкнутая система и на драйвере колеса даже 2 разьёма rx/tx .
Какой то протокол выложен на первых страницах и можно попытаться залить скетч в ардуино.
Ну и 118 страниц мусора и люди докупаются какими то ненужными запчастями и делают грабли.
Если по существу , то из навесной коробки нужно выкинуть GPS/GSM модуль и оставить преобразователь напряжения . Ну и добавить своё для команды всё OK.
Или , искать прошивку на драйвер колеса. Но птица не ninebot . Здесь никто даже не обсуждает статус батареи и что именно этот статус обрабатывает.
Просто пишу для нулевых чайников . Самокаты замкнутая система . Нельзя купить постороннее дерьмо от других систем и запихать.

Hello everyone

I thought I would share what I’ve found on the Lime GPS/Cellular module so far. I was given two Lime front green boxes to play with.

The green box contains two boards, the larger board contains the main processor, Bluetooth module, GPS module and voltage regulators. The smaller board looks like it is simply a voltage regulator, dropping the battery voltage down to 5V.

The main chip on the SLT181 board is a MeiG Smart SLM750 LTE (cellular) chip with UART (Serial), USB 2.0, Bluetooth HCI and I2C interfaces. The CPU is a Qualcomm ARMv7 and is running a Linux 3.18 Ubuntu kernel.

The board also contains a SIM card on the bottom. The SIM is from Twilio who offer a “super sim” which can be used internationally to send data via SMS or Mobile data.

https://www.twilio.com/wireless/super-sim

I powered the board with a USB to Serial converter connected to the serial pins of the plug. I have included the pinouts that I know so far.
The issue I have is that the chip boots until I get “Error code 303e at boot_flash_dev_nand.c Line 571”
The chip has NAND flash on board so I’m not sure if the error is referring to the on-chip NAND or if it is trying to contact storage elsewhere on the same or another board?

If I drop the Serial TX to earth for 2 seconds at boot, I can put the SLM750 into a programming mode and get an almost full boot. If I earth out Serial TX for 5 second-ish, I get a different boot sequence but both end with a kernel panic and a reboot back to the error code 303e.

The links below are to Pastebin showing the default boot, the 2 second earth and the 5 second earth.

Default boot: https://pastebin.com/PiV3xiGS
2 second earth: https://pastebin.com/eCA5VPx8
5-ish second earth: https://pastebin.com/ed85ceeQ

This is the pinouts of the main plug on the main board.

If anyone has anything to help me get the chip to fully boot I would like to hear from you.

Hello, i have a full boot.

Nice work. The boot information will be handy.
Did you still have the SIM connected while booting? I think my issue was that I removed the SIM and GPS.

Hi everyone, I can buy HIVE scooter cheap at auction (ninebot ES2 without external GPS box) but I would like to summarize first if it will be profitable.
1. I disassemble the GPS from the bottom of the scooter (probably 4-bolt)
2. I disassemble the dashboard (after about 1 hour the scooter will be unlocked?) Then I update the software
3. I am happy with the purchase;)

is everything correct?

Do you happen to have detailed instructions on how to connect this into a lime scooter ninebot es2?
