The following instructions are for setting up a brand new Coin BLE Dev Board for easy programming with the Arduino IDE and Bluetooth integration. Even though the original boards sold out and Coin did not plan on doing another manufacturing run, many people were still interested in getting their hands on these boards. Because of this, our team took over the second manufacturing run so that everyone who wants the board can get one.
To purchase your own Coin BLE Dev Board (NO LONGER AVAILABLE), visit http://coindev2.myshopify.com/
The boards come assembled fresh from the factory, so this post documents the steps that must be followed to get your board programming ready.
To Program the BLE module:
- For default BLE behavior (send 1 byte at a time from the Arduino via Bluetooth) or if you do not want to write any custom code for the BLE module, program the out1-19-NOV-2013.hex file provided on the Coin Wiki (Git Hub Link to code)
To Program the Bootloader on the Arduino
2 Methods:
- Using the Atmel mkII AVRISP Programmer
- Using another Arduino and the Arduino IDE
Method 1: Atmel mkII AVRISP Programmer
Requirements:
Instructions:
1) Place 6 pin header into the FTDI cable
2) Wire the following pins up to the mkII programmer (no need to solder them in, just bend to ensure pin contact)
3) Place FTDI cable into dev board for powering the board (the red light will be on). Make sure you orient the FTDI cable correctly when you connect it (the board says GRN on the side that corresponds to the green wire on the FTDI cable)
4) Open up Atmel Studio 6: Tools >> Device Programming
5) When the programming window pops up, set up the following properties
6) Click Apply
7) IMPORTANT: Under the Interface Settings tab, set the ISP Clock to 125kHz (for the first time this must be done since the fuse settings haven't been set yet)
8) Under the Memories tab, browse for the ATmegaBOOT_168_atmega328_pro_8MHz.hex bootloader (under most normal Windows installs, this will be located under C:\Program Files (x86)\Arduino\hardware\arduino\bootloaders\atmega\)
9) Click Program
10) Upon success, go the the Fuses tab and set the fuses to the following:
11) Click Program
12) Now verify that the bootloader was properly loaded by opening up the Arduino IDE and loading the "Blink.ino" file onto the dev board using the FTDI cable only as the following describes:
- Select the proper serial port where your FTDI programming cable is plugged into
- Under Board, select Arduino Pro or Pro Mini (3.3V, 8MHz) w/ATmega328
Method 2: Use another Arduino as a AVRISP programmer
The second method is to use another Arduino to program the bootloader. This can be done with the setup seen below, except for replacing the top Arduino with the dev kit board. Modified from http://arduino.cc/en/Tutorial/ArduinoToBreadboard.
If you have a new ATmega328 (or ATmega168), you'll need to burn the bootloader onto it. You can do this using an Arduino board as an in-system program (ISP). If the microcontroller already has the bootloader on it (e.g. because you took it out of an Arduino board or ordered an already-bootloadedATmega), you can skip this section.
To burn the bootloader, follow these steps:
- Upload the ArduinoISP sketch onto your Arduino board that you will be burning the bootloader from (You'll need to select the board and serial port from the Tools menu that correspond to your board.) This can be found in the Arduino IDE at File >> Examples >> ArduinoISP. Upload this sketch to the device.
- Wire up the Arduino board and microcontroller as shown below. The 4 yellow wires in the image from the programmer Arduino should instead be contacted with the following pins on the dev board (once again, just make sure you have contacts on the pins using the jumper wires rather than soldering them completely in if you want to save some time):
- PIN 13 on programmer Arduino <--> PIN 13 on dev board
- PIN 12 on programmer Arduino <--> PIN 12 on dev board
- PIN 11 on programmer Arduino <--> PIN 11 on dev board
- PIN 10 on programmer Arduino <--> RST on dev board

- Select "Arduino Pro or Pro Mini (3.3V, 8MHz)w/ATmega328" from the Tools > Board menu (see below ):
- Run Tools > Burn Bootloader > w/ Arduino as ISP.
- Finally, select Burn Bootloader from the Tools menu to burn the bootloader onto the board.
Now verify that the bootloader was properly loaded by opening up the Arduino IDE and loading the "Blink.ino" file onto the dev board using the FTDI cable only.
You should only need to burn the bootloader once. After you've done so, you can remove the jumper wires connected to pins 10, 11, 12, and 13 of the Arduino board.
- Connect the FTDI programmer to the dev board (see above steps on how to do this)
- Select the proper serial port where your FTDI programming cable is plugged into
- IMPORTANT: Under Board, select Arduino Pro or Pro Mini (3.3V, 8MHz) w/ATmega328
- Click Upload Sketch button in the IDE

- Download the example code seen here from the Wiki
- Load the code onto the Arduino in the same manner as you did the "Blink.ino" above
