NeOCampus RC car example code - both versions (Arduino and Raspberry Pi) Author Sebastian Lucas - 2019-2020
The following document explains how the whole setup and protocole works Both versions use the exact same protocole but support different functionality
Protocol: We use 2 bytes to control the vehicule, the first one for left/right and the second one for fowards/backwards
The range of the positions (power) is between -100 and 100.
UP: 0, power DOWN: 0, -power LEFT: -power, 0 RIGHT: power, 0 STOP: 0, 0
Bluetooth: Service UUID: 00001101-0000-1000-8000-00805f9b34fb Caracteristic UUID: 00002101-0000-1000-8000-00805f9b34fb
For testing purposes we can use an Android / Windows 10 app called "BLE simple remote" It is important to use the following settings:
-
Byte Mode: Enabled: Positions are transfered as bytes.
-
Zero: Enabled: Car will stop when releasing button.
-
Channel (Ch.): Disabled.
