intercepting yellow wire
Hi! Tks for the project!! Did you intercept the yellow wire as an Y wire? Or did get for BLE or ESC side only?? Can you understand my doubt? Tks!
Hey mate! work was done only by sniffing data between the uart single wire between BLE and ESC ;) if you need to get data from for instance ESC <-> IOT or ESC <-> BMS you might need to add two diodes and a pull-up resistor to analyse at the same time the TX / RX lines
Tks so much for answer!!! Do you have a schematic of this wire?? Could you sketch some one??
I saw same exemples but some of that we need and external vcc, another we need and npn transistor...

Tks so much!!! Best regards! Emerson [image: Mailtrack] https://3.bp.blogspot.com/-DOIIi1WVP5Q/UtIBrFJqJoI/AAAAAAAAhc0/1i5h2j1n9Rk/s1600/1WireSerial.png Remetente notificado por Mailtrack https://cnnblike.com/post/stm32-OneWire/blog002-008.png 10/05/20 11:36:19

Well if you want to watch both TX and RX lines from the escooter, either you can use an arduino mega with its 4 uart to monitor both data lines. If you're using a uno or another single-uart device, give a try to the following schematic (diodes can be 1N4148, or even better with Schottky types)
I did not tried this, but it should work, given the fact serial lines are active low, diodes became to conduct, bringing the Uno_Rx line voltage to low level as well, thereby combining both half duplex RX & TX signals from the scooter
