Maybe make sure you have selected the right COM port, with the right properties :

Open device manager and see which COM port is added to the list when you plug the CH340G in your computer)

When I right click on it and show properties, in the port settings tab I see :

Bits per seconde : 9600

Data bits : 8

Parity : none

Stop bits : 1

Flow control : none

 

and here are the pins soldered :

It worked by soldering pins to 3.3V GND TXD and RXD and using LBMC v121.18.0329

my controller reference is ZWK060035 1200W

in a Lifan E3 ( youbee city 50 / pink me )

Hi,

I was following a tutorial to change settings of a lingbo controller, but the plug on my scooter is different.

The tutorial say to connect RXD to white cable (image 1), but my plug doesn’t have a white cable, so I tried connecting to the only unused pin on the 6 pin plug (image 2).

When testing this layout, the USB to TTL stick only has a red LED on, but when I switch RXD and TXD I also get a blue LED (both timeout on every versions of LBMC i could find).

The red LED is on when the USB in plugged but nothing else so I am guessing it indicates power.

The blue probably indicate data transfer but should probably blink to show activity (since the best I could get was for it to stay lighted, the wiring is probably wrong).

When openning my controller (ZWK060035 1200W) I found testpoints (image 3) with legends saying “3.3V SWCLK GND SWDIO GND TXD RXD” which could be a solutions, but is it safe to try?

I will probably try with that in a few days, but i’m not sure yet how to have a reliable connection to those points (last resort will be soldering pins to the holes).
