---+ BLE Application Software for the Velo Bling-Bling Project

LED lights for bicycle wheels.
16 multi color LEDs on both sides (PCB top- and bottom side).
There are two windows (upper and lower) on both sides 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 [[https://github.com/LairdCP/UwTerminalX][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 [[https://github.com/LairdCP/UwTerminalX][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.

<img src="%ATTACHURLPATH%/connect-UwTerminal.png" alt="connect-UwTerminal.png" width="642" height="421" />

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

<img src="%ATTACHURLPATH%/cli.png" alt="cli.png" width="642" height="421" />


and type
<verbatim>
CLI> ble reset
CLI> ble trans
</verbatim>

Show the firmware version:
<verbatim>
ati 3
</verbatim>
 
<img src="%ATTACHURLPATH%/erase-ffs.png" alt="erase-ffs.png" width="643" height="421" />

---+++ 2. Delete the File System
<verbatim>
atz 
at&f 1
</verbatim>

<img src="%ATTACHURLPATH%/erase-ffs.png" alt="erase-ffs.png" width="643" height="421" />


---+++ 3. Download and Compile the LP Application

Press the right mouse button and select =XCompile + Load=. Choose the file  =lp.low.power.deep.sleep.sb=.

<img src="%ATTACHURLPATH%/lp-download.png" alt="lp-download.png" width="687" height="587" />

---+++ 4. Download and Compile the BLING Application

Press the right mouse button and select =XCompile + Load=. Choose the file  =bling.vsp.sb=

---+++ 5. Check Filesystem
<verbatim>
at+dir
</verbatim>
The applications =lp= and =bling= have to be listed.

<img src="%ATTACHURLPATH%/dir.png" alt="dir.png" width="642" height="422" />

Press Ctrl-D to exit transparent mode.


---++ 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
<verbatim>
CLI> ble reset
CLI> ble trans
</verbatim>

Show the firmware version:
<verbatim>
ATI 3
10    3    1.2.54.0
00
</verbatim>
 
---+++ 2. Connect Debug Adapter
Connect a debug adapter to the JTAG connector. 

---+++ 3. Save the License Key
With a terminal program (e.g. !UwTerminalX):
<verbatim>
ATI 49406
10      49406   1696553225C4BC8CE19A
</verbatim>
Write down the license key (similar to =1696553225C4BC8CE19A=)

---+++ 4. Download the Firmware
On a Windows-PC start the the firmware batch program
<verbatim>
_DownloadFirmware_v1_5_70_0.bat unlicensed
</verbatim>

---+++ 5. Restore the License Key
With a terminal program (e.g. !UwTerminalX):
<verbatim>
AT+LIC "1696553225C4BC8CE19A"
</verbatim>
