Microblu OS allows you to connect and control your Arduino via the Octoblu Meshblu (formerly SkyNet.im) open source IoT platform and API.
Microblu OS supports Arduino ethernet or wifi shields (or any other device that properly implements the Client interface)

##Getting Started with Arduino
NOTE: The CC3200 LaunchPad requires the Energia IDE, see CC3200 instructions.
To use microblu on Arduino compatible devices you will need to install the Arduino IDE and some required libraries.
Required Downloads:
Proceed after you have successfully installed the Arduino IDE
###Installing Libraries
- Unzip the libraries you've just downloaded and rename the folder for each library removing anything like "- master"
- Open Arduino and go to Sketch->Import Library->Add Library and choose the main folders you renamed
- If you goto File->Examples you should see microblu_mqtt
- Choose the example that corresponds to the shield you will be using before proceeding.
##Configuring your code
First you need a valid UUID and Token from Skynet. Copy and paste the following into a terminal window, and put the resulting UUID and TOKEN in your sketch.
NOTE: In windows use a terminal emulator such as CYGWIN
curl -X POST -d "type=firmwareController&payloadOnly=true&name=Arduino" http://skynet.im/devicesEnsure the following have been added to your sketch:
- UUID
- TOKEN
- WIFI Credentials (if using wifi shield)
Save this sketch and move on to the corresponding tutorial!
##Install Wifi
These are instructions for Arduino brand wifi
IMPORTANT: Connect the IOREF pin to the 3.3v pin. If you’re using the Rev3 series Arduino controller, you don’t need to do this!
###Step 1 - Test your WIFI shield
Open the sketch: File->Examples->WIFI->WiFiWebClient.
Put your connection details in and make sure it gets a connection to google that looks like this:
####Firmware Update If you've never updated your Wifi shields firmware, you'll see a message to update your firmware. Please do:
- http://arduino.cc/en/Hacking/WiFiShieldFirmwareUpgrading
- For Windows http://www.dfrobot.com/community/how-to-upgrade-arduino-wifi-shield-firmware-on-windows.html#comment-9233
###Step 2 - check configuration
Open microblu_wifi example at File->Examples->microblu_mqtt and follow the "Configuring your Code" section above if you haven't
Double check your wifi credentials!
Lastly
- Check Tools->Port and Tools->Board and make any neccesary changes
- Upload your code
- Open a serial monitor and listen in at 9600 baudrate (this is how your Arduino will tell you if something broke)
####Pins In use by Shield (Do not use these pins for anything else)
- 7, 10, 11, 12, 13
- If the SD card is in use Pin 4 will also be unavailable.
##Install Ethernet
These are instructions for Arduino brand ethernet shields and boards
Open microblu_eth example at File->Examples->microblu_mqtt and follow the "Configuring your Code" section above if you haven't
It might be wise to alter the stock MAC address. If you ever have two of these on the same network you'll have trouble otherwise.
Lastly
- Check Tools->Port and Tools->Board and make any neccesary changes
- Upload your code
- Open a serial monitor and listen in at 9600 baudrate (this is how your Arduino will tell you if something broke)
####Pins In use by Shield (Do not use these pins for anything else)
- 10, 11, 12, 13
- If the SD card is in use Pin 4 will also be unavailable.
##Install CC3000
These are instructions for any board using a CC3000 chip regardless of manufacturer. We prefer Sparkfun:
####Install Dependency The only library we know of that properly implements the Arduino network client library for the CC3000 is Sparkfun's and as long as you have any shield that uses a CC3000, donwnload and install their library as before:
###Test Connection
The first thing you should do is see if your shield and network work by using the standard wifi test at File->Examples->SFE_CC3000_Library->PingTest.
Put your connection details. You'll also have to change the pins to match whatever shield you have. The default pin setup is for sparkfun. If you have adafruit you might use:
#define CC3000_INT 3 // Needs to be an interrupt pin (D2/D3)
#define CC3000_EN 5 // Can be any digital pin
#define CC3000_CS 10 // Preferred is pin 10 on Uno
Open a serial monitor to 9600 Baudrate and check that you're connected (this may take a minute)
If it connects, we're all good. Open microblu_cc3000 example at File->Examples->microblu_mqtt.
**Follow the "Configuring your Code" section above. **
Don't forget to change out your pins and wifi or other networking credentials here too.
Lastly
- Check Tools->Port and Tools->Board and make any neccesary changes
- Upload your code
- Open a serial monitor and listen in at 9600 baudrate (this is how your Arduino will tell you if something broke)
####Pins In use by Shield (Do not use these pins for anything else)
- 11, 12, 13 and any other pins you've set above.
One note about the cc3000 is it is a VERY big library. We've had to make a few changes. The sketch no longer supports capabilty query. Most likely that doesn't mean anything to you so don't worry about it.
##Install CC3200 WARNING: CC3200 support is experimental and still in development, some functionality may not yet be supported.
These are instructions for a CC3200 LaunchPad:
Clone a forked version of Energia:
git clone --depth=1 https://github.com/erikwilson/Energia.git && cd Energia
Build Energia:
(cd build && ant)
Install extra libraries:
(cd libraries && ./copy_libs.sh)
Install microblu_mqtt:
mkdir -p sketchbook/libraries && \
(cd sketchbook && git clone https://github.com/octoblu/microblu_mqtt.git && \
cd libraries && ln -s ../microblu_mqtt .)
NOTE: Ensure that the CC3200SDK-SERVICEPACK is installed within Windows (emulation with Wine will not work) and jumpers are set per TI instructions when flashing with Uniflash.
When uploading sketches with Energia the SOP2 must be jumped to TCK, see:
(cd build && ant run)
Set the sketchbook folder to the folder created in Energia.
Open the CC3200 sketch through File -> Sketchbook -> microblu_mqtt -> microblu_cc3200.
Follow instructions for configuring your code.
##Install Spark
These are instructions for a Spark Core:
The Spark does NOT uitlize Arduino. Unless you're an advanced user this is very difficult until we can get all the libraries we need in the Spark online IDE. Follow the directions below, but you can also see a working example in our experimental branch at: https://github.com/jacobrosenthal/core-firmware/tree/skynet-mqtt-firmata
Follow the instructions on their site to custom build: https://github.com/spark/core-firmware
Also requires our fork of firmata https://github.com/jacobrosenthal/arduino/tree/Spark
And Teensy's pgmspace.h https://github.com/jacobrosenthal/core-firmware/blob/skynet-mqtt-firmata/inc/pgmspace.h
Once you can successfully custom build, you need to dump all the cpp files in /src and all the h files in /inc. Replace application.cpp with this file
Add your UUID and TOKEN from before.
Upload away. You can open the Arduino Serial Terminal at 9600 to see your connection status.
##USE
Now you can use Nodeblu Designer or Node.js to command and control your Arduino.
