Bluetooth Low Energy project to control an arduino with a command interpreter via serial uart

Primary LanguageArduinoMIT LicenseMIT

CommandInterpreter is a shell-like command interpreter that parses one command + two arguments per line from char buffer of a serial connection, which is a Bluetooth Smart (low energy) UART in this case. One command is limited to 20 chars as the UART nRf8001 Bluefruit hardware cannot process more than that in one UART message/packet. Return messages can be assembled by the software on the smartphone to larger messages.

Example commands:

  • "blink" with argument "on" or "off": blink [ on | off ]
  • "pmode a0 o" ... pinMode(A0, OUTPUT)
  • "dwrite a0 h" ... digitalWrite(A0, HIGH)
  • "pmode d1 o" ... pinMode(5, OUTPUT)
  • "awrite d1 128" ... analogWrite(5, 128)
  • "pmode d2 o" ... pinMode(6, OUTPUT)
  • "awrite d2 64" ... analogWrite(6, 128)

Download and install the dependent library Adafruit_nRF8001

Use an UART Serial App like this: https://itunes.apple.com/at/app/nrf-toolbox/id820906058?mt=8

USAGE:

#define CMD_MAX_COMMANDS 7
#include "CatsCommandInterpreter.h"
CatsCommandInterpreter commandInterpreter = CatsCommandInterpreter();

boolean command_blink(char* arg1) {...}

setup() { commandInterpreter.addCommand("blink", command_blink); }

rx() 
{
  if(commandInterpreter.interpretCommand(buffer, len)) // check if command can be interpreted
    return;  // do not echo if command was a success
}
