WltoysControl

Control Wltoys cars from your PC with an esp32 and nrf24l01.

This is a full implementation of wltoys v202 protocol,specified for rc cars A959, A969, A979 using nrf24l01 and esp32 (or esp8266). The idea of this project come from (https://github.com/nobotro/wltoys-v202-protocol). I prefered to use the arduino framework with platformIO and the serial interface. Project don't need any modification of car and you don't need a controller.

Usage

• Compile the main.cpp and upload it to your esp
• Connect nrf pins correctly(we use software spi) 'miso': 32, 'mosi': 33, 'sck': 25, 'csn': 26, 'ce': 27
• Run "remoteSerial.py" in your pc with your esp connected on your serial interface. You may change the COM port number.
• Keymap is mapped for AZERTY keyboard
• Key 'z' -> go forward
• Key 's' -> go backward
• Key 'q' -> steer left
• Key 'd' -> steer right
• Key 'a' -> decrease time to get full throttle
• Key 'e' -> increase time to get full throttle
• Key.up -> increase gear
• Key.down -> decrease gear
• Key.left -> steer trim
• Key.right -> steer trim
• By default, you begin with gear 6 and can downgrade to 1 or upgrade to 13, time to get full throttle is 1600 ms
