This is a quick Node.js project developped to demonstrate how to parse communications logs extracted from the Ninebot electric scooters internal serial communication bus.

git clone https://github.com/rascafr/9-analyzer.git

cd 9-analyzer

npm i

Either production or development (code monitoring, nodemon required)

# prod
npm start

# dev
npm run dev

Use a serial-USB adapter, and use the following settings:

• 115200 bd/s
• 8 data bits
• 1 stop bit
• no parity

Incoming data will be sent by the scooter on the yellow wire connected to the dashboard.

Ground (OV) is the black wire. Connect both files to your serial-USB adapter on RX and GND.

Some Arduino code is present insinde of this repos, can be used to parse on the fly some of the serial commands in "realtime".
