XBee Stacker 2

The Stacker is an XBee radio-sized Arduino-compatible microcontroller that can be “stacked” directly underneath the radio. It is intended for use with devices that already use the XBee’s 20-pin footprint. Future designs could easily utilize other microcontrollers or host sensors.  The goal is to create plug-and-play tools for prototyping new concepts that extend the popular radio’s feature set. A few iterations have created a prototype that works well, supports USB programming, wireless programming, I2C, SPI, digital and analog I/O!

XBee Stacker 2

This is the next iteration of an Arduino-compatible board the size of an XBee that fits right underneath the radio. It uses the ATMega32U4 so in Arduino you can program it as a Leonardo board.

Digi Employee Hackathon: XBee Wi-Fi Visits Logroño

logrono-lie-detect-robFor the latest Digi Hackathon, I headed overseas to hold our first ever creative construction event at Digi’s office in Logroño, Spain. Using XBee WiFi Cloud Kits, the four teams hacked away for what was the most competitive session yet. In a matter of hours, each team had to quickly brainstorm, build, and present their cloud-connected projects. Their results were terrific.

Projects included:

  • The Garbage M.A.N.: Smart garbage containers monitoring for smart cities
  • Germinator Plus: An automated system for remote greenhouse seed germination monitoring.
  • Lie-Detect-o-Meter: A mobile battery-operated wristband lie detector for public questioning.
  • The Smart Plug-Y-Play: A power consumption monitor and remote control for computers and other electrical appliances.

Digi Employee Hackathon: XBee Wi-Fi Cloud Kit

Hack10

Last week, we held a Digi Employee Hackathon to put the new XBee Wi-Fi Cloud Kit to the test. This is one of several ways we are working on designing outstanding user experiences for new Digi products. With the kits, the teams were able to build projects that connected with the cloud right away. One team member reported, “I got from the box to the cloud in under 20 minutes.” Using the kit’s dashboard, new widgets were  developed to whimsically represent data being collected by Device Cloud. Rain, food safety and even child development were addressed by our project teams.

I’m looking forward to doing more of these internal hackathons in the coming year. They’re fun!

Wireless Programming (Arduino XBee OTA)

This XBee Stacker can be programmed wirelessly using an Arduino setup first prototyped by me, then greatly improved by Limor Fried and later Shigeru Kobayashi. I’m borrowing it back now, thanks everyone!

Parts

2 – XBee 802.15.4

1 – XBee Explorer USB (or XBIB, or similar)

1 – USB cable

Configure Your XBees

XBees are factory configured for 9600 baud. The Arduino IDE typically sends programs (sketches) at 57600 baud. In addition, Arduino needs to reset the microcontroller on your remote board just before sending over a new sketch. This is cleverly accomplished by linking one of the base station’s hardware handshaking lines briefly to the reset line on the remote Arduino-based microcontroller. Here’s the chain of events:

  1. User clicks the upload button in the Arduino IDE. That’s it! The remaining steps happen automatically…
    • Arduino (technically AVR Dude) opens the local serial port, automatically bringing the RTS line low.
    • The RTS line is connected to pin DIO3 on the local XBee Explorer so that pin it goes low in tandem.
    • The local, base station XBee has pin DIO3 configured as a digital input, and sends that low state to the remote XBee, the one plugged in to the XBee Stacker board.
    • The remote XBee has pin DIO3 configured as a digital output, initially high. When it receives the low state from the base station XBee, its own DIO3 goes low too.
    • DIO3 on the XBee Arduino Stacker is connected to the Arduino microcontroller’s reset line, but via a capacitor so only a burst of the low signal gets through, just enough to reset the microcontroller.
    • The reset microcontroller goes into bootloader mode and accepts your new Arduino sketch over-the-air, then begins running that new sketch. All by itself and without wires!

Label one XBee “Base” and use X-CTU, CoolTerm or even the Arduino IDE’s Serial Monitor to give the “Base” XBee the following settings:

PAN ID 1234 ->  ATID 1234 (I recommend that you choose your own unique PAN ID)
MY ID 1 ->  ATMY 1
DESTINATION HIGH 0 ->  ATDH 0
DESTINATION LOW 2 ->  ATDL 2
BAUD RATE 57,600 ->  ATBD 5
DIGITAL IO 3 input ->   ATD3 3
CHANGE DETECT 3 on ->  ATIC 8

Label the other XBee “Remote” and give it the following settings:

PAN ID: 1234 ->  ATID 1234 (always match the “Base” radio’s PAN ID)
MY ID: 2 ->  ATMY 2
DESTINATION HIGH: 0 ->  ATDH 0
DESTINATION LOW: 1 ->  ATDL 1
BAUD RATE: 57,600 ->  ATBD 5
DIGITAL IO 3: output high ->   ATD3 5
INPUT ADDRESS 1: -> ATIA 1
UART OUTPUT disable ->  ATIU 0

If you are using CoolTerm or another Serial Terminal, use ATWR to save the configuration to your XBee’s firmware.

After you change their baud rate the radios will no longer respond at 9600 baud. Be sure to change the baud rate in X-CTU or CoolTerm to 57600 if you want to check or update their configurations.

Configure Your Hardware

The “Base” XBee’s DIO3 and RTS pins need to be connected together. If you are using an XBee Explorer, simply solder a jumper or wire between these two pins.

Nate at Sparkfun shows the solder jumper you will need.

(If you are using Digi’s XBIB board or a different adapter, find the appropriate pins and then short them together either with some solder or with a bit of wire. Either method is reversible.)

Upload Sketches

Now you can start uploading Arduino sketches wirelessly! Simply:

  1. Connect your “Base” XBee into the modified XBee Explorer USB  (or  your own adapter) connect it to your computer with a USB cable.
  2. Stack your “Remote” XBee onto the XBee Arduino Stacker and provide it with power (a second Explorer or XBIB is an easy way to power it for tests).
  3. Select “Arduino Uno” in the Tools:Board menu and select the correct serial port from the Tools:Serial Port menu.
  4. Open the sketch you’d like to upload.
  5. Click the Upload button!

Should you get an error message, try again in case it’s just a one-time glitch. Next carefully recheck each connection and configuration item, one at a time. It’s very common to get something set wrong the first time you try this so go through it methodically and patience will pay off.

Digi Deploys 500-Node Internet of Things Network for Data Sensing Lab at Google I/O

Michael-Explaining-the-Data

This week we are taking part in deploying over 500 sensor motes at Google’s developer conference, Google I/O, May 15-17. The network will make up the Data Sensing Lab, a project that utilizes Digi’s XBee ZigBee modules and ConnectPort wireless gateways. The sensor data will be collected and managed by Device Cloud. The project demonstrates how real-time machine-to-machine data can provide insight into customer behaviors and preferences.

The senor network will provide more than 4,000 data streams running over Device Cloud with continuous updates on temperature, pressure, light, air quality, motion and noise levels in San Francisco’s Moscone Center during the conference. The Google Cloud Platform team will gather, transform, and analyze the information, then share heat maps and other data visualizations in collaboration with the Google Maps team.

Google is getting a global view of their entire multi-million dollar event, as it plays out in real time. They’re learning where people are going and when, how loud the applause is for each presentation, where it’s figuratively hot and where it’s literally cool. But they’re also learning how easy it is to integrate Device Cloud’s APIs with their own cloud-based business systems. Google and Digi collaborated to create a complete end-to-end solution in just a few weeks, one that’s ready to hand us 40 million fascinating data points.”

The Data Sensing Lab crew, Alasdair Allan of Babilim Light Industries, Kipp Bradford of Kippworks, Rob Faludi of Digi International, Michael Manoochehri, Amy Unruh and Kim Cameron of Google and Julie Steele of O’Reilly Media, created the project to collect data to answer questions about the physical world in a fun and awe-inspiring way. For more information about the software involved in this project, attend the “Behind the Data Sensing Lab” session on May 16, 5:20 – 6 p.m. PDT.

Here’s a bit of the press we’ve gotten so far about the project:

 

Strata Big Data Video Interview

I spoke live with Mac Slocum at O’Reilly’s Strata Big Data conference about Digi International’s involvement in the Data Sensing Lab here, as well as the future of M2M and the Internet of Things-what I’m hoping will be an Internet of Things People Want. Our part in the lab was to assemble a network of 40 XBee ZigBee radio sensor nodes running Arduino, gateway their data via a ConnectPort X2e running the XBee Internet Gateway and post everything to the iDigi Device Cloud where it could be passed off via Amazon Web Services to a team of visualization experts for analysis. Here’s the interview:
