Description

A basic getting started application for BLE and FreeRTOS.

Usage

LEDs

The red LED will indicate that an error assertion has occurred.

The green LED indicates CPU activity. When the LED is on, the CPU is active, when the LED is off, the CPU is in sleep mode.

Expected Output

On startup:

help Displays the available commands.
echo (on|off) Enables or disables the input echo. On by default.
btn (ID) (s|m|l|x) Simulates button presses. Example: "btn 1 s" for a short button press on button 1.
pin (ConnID) (Pin Code) Used to input the pairing pin code.

Push buttons

Push buttons can be used to interact with the application.

short press is less than 200 ms
medium press is between 200 and 500 ms
long press is between 500 and 1000 ms
extra long press is greater than 1000 ms
