BLE Application Software for the Velo Bling-Bling Project

LED lights for bicycle wheels. 16 multi color LEDs on each side (PCB top- and bottom side). There are two windows (upper and lower) on each side for display dynamic information like speed, trip time, trip distance, etc. or static information like strings and images. The windows have a resolution of 100 x 16 pixels. The space between the windows can be filled with a pattern/image (AKA blingbling).

This application software runs on the BL600 Module (BLE slave) and communicates over the UART and I2C interface with the main MCU (MK22DX256VLF5).

BLE Master (e.g. Smart Phone) <-> BLE Slave BL600 UART & I2C <-> main MCU

The BLE Master can use the propriarity vSP Bridge Mode to communicate over the UART with the main MCU like a serial terminal (Command Line Interface CLI). The Cycling Speed and Cadence Service (CSC) is a standard Bluetooth service, data are exchanged between main MCU and BL600 by I2C.

The USB CDC on the main MCU can be used as a terminal interface for the BL600 module. You can use the UwTerminalX for communicating and downloading applications onto Laird's BL600 module.

UwTerminalX

UwTerminalX is a cross-platform utility for communicating and downloading applications onto Laird's range of wireless modules, and uses Qt 5. UwTerminalX has been tested on Windows, Mac, Arch Linux and Ubuntu Linux.

More infos and download, see UwTerminalX.

Bluetooth Low Energy (BLE) Development Kit DVK-BL600

The Laird BLE development kit provides a platform for rapid wireless connectivity prototyping, providing multiple options for the development of Bluetooth Low Energy (BLE) applications.

You can use the Velo Bling-Bling hardware in similar way to develop an download BLE applications. You do not need a DVK-BL600. Unfortunately the UwTerminalX can not communicate with the Velo Bling-Bling USB CDC (/dev/ttyACM) under GNU/Linux, you have to use Windows

Segger J-Link LITE CortexM

This debug adapter is included in the Bluetooth Low Energy (BLE) Development Kit DVK-BL600. This adapter is needed for downloading a new BL600 firmware.

Download the Application into the BL600 Module

1. Connect Terminal

Connect the the Velo Bling-Bling USB to the PC with a Micro-USB cable. Start the terminal program (UwTerminalX). Choose the the communication (serial) port and click the OK button.

Press the Escape-Key and then the Return key, wait for the CLI> prompt.

Update the BL600 Firmware

This is only needed if you want to use a new BL600 firmware (Velo Bling-Bling works with version 1.5.70.0 and newer, 1.2.54.0 is not tested). Firmware update is only possible with a debug adapter (e.g. Segger J-Link LITE CortexM) over the JTAG interface.

1. Connect Terminal

Connect the the Velo Bling-Bling USB to the PC with a Micro-USB cable. Start a terminal program (e.g. UwTerminalX). Hit the Escape-Key, wait for the CLI> prompt and type
