Here are some links to photos of the boards.

I’ve taken hundreds of photos of the various versions of the boards, but we only post the resized photos here on the website. I think the highest resolution one currently online is this one:

I can certainly upload some other photos if you’d like a different angle or with…[Read more]

How did you verify that the board isn’t going into sleep mode? Can I assume that you didn’t modify the pads on JP1 and that the clock interrupt is still connected to A7 and you didn’t do anything with D10 other than use the D10-D11 grove port for connecting your sensor?

We’ve been busy getting the Mayfly and starter kits back in stock, so now that they’ll be online any day now, we can work towards getting the proto boards listed, so look for those in early April.

For anyone wanting an update on the Mayfly availability, the boards arrived at my office last week from the manufacturer, and after thorough testing of each one, I sent off the first shipment of them to Amazon. Once Amazon has incorporated them into their fulfillment system, the product listings will show that they are in stock and can then be…[Read more]

There are several different methods you can use to wake a sleeping processor using a realtime clock. The example I posted uses the method of triggering an interrupt pin on the processor by using a quick pulse that the RTC puts out every minute. By doing this, the processor can wake up each minute and then it’s up to the user’s code to examine…[Read more]

I’m not sure where you saw something that said the Mayfly only supports a 2.5W panel, because that’s not accurate. The only limiting thing is the voltage that the panel produces — the Mayfly only works with panels with an output voltage of 6 volts. If you use a solar panel with a 9v or 12v output, you will damage the Mayfly.

The reason for the…[Read more]

I am still awaiting the shipment of the latest order from the manufacturer. They had a 3-week holiday last month that put their production almost a month behind schedule. I also had do to an extra round of prototype testing in January because we’ve added and changed a few things on the new v0.5 board. Once I get the new boards, I thoroughly…[Read more]

Just do the software fix as suggested above and leave the clock interrupt on A7, then you won’t have to worry about doing any wiring changes. I added the D10 interrupt option on version 0.4 and higher because I thought it might come in handy for people who had interrupt library complications. But it works just fine if you simply use the modified…[Read more]

The error you’re getting is because the SoftwareSerial library uses an interrupt method that conflicts with the SODAQ_PcInt library. In order to use those 2 libraries together, you have to use the modified versions of the libraries we posted in our Github repo, along with modifying the library names in your sketch in 3 places. Plus you’ll need…[Read more]

First you have to download the Arduino library for the SSD1306 by following the link on the Amazon listing to the manufacturer’s site which will then let you get to their own product listing: http://store.switchdoc.com/grove-128×64-i2c-oled-board-for-arduino-and-raspberry-pi/
On that page there’s a link to their library on…[Read more]

Try this: use X-CTU to reprogram both of the Xbee modules to 9600 baud and then change the baud rate in your Fio sketch to 9600 for the serial port and also 9600 for the software serial port (it’s easier and less confusing if everything uses the same rate). I’ve had trouble in the past with some of my Xbee units printing garbled text to the…[Read more]

Hi Dan and Jim,

You were at the Stroud Center last week attending one of our sensor station workshops, so your situation is a little different than most users on the forum. I’ll send you an email with more information about the stations and sensors and how we’ll be working with you in the coming months.

I’m going to need more information if you want me to diagnose your problem. When you say “it doesn’t work”, do you mean that it doesn’t compile, or there’s no output on the serial monitor, or is there nothing transmitted by the Xbee?

Also, please answer these questions:
What type of USB-to-TTL adapter are you using to program the Fio?
How is…[Read more]

Past your code into this thread and I’ll take a look at it. Also, did you change the baud rate of the Xbee modules using X-CTU, or are they still set to the default?

Also, if you’re ever having trouble with a new sketch because you’re testing several new sections together for the first time, try removing some of them to simplify it and make sure…[Read more]

If you’re using the Fio board, then your Xbee is forced to use the only hardware serial port on the board (pins 0 and 1). So if you really want to print out data to the serial port at the same time, you’ll need to use 2 other pins for that, using SoftwareSerial. I assume you’re using a FTDI adapter for connecting your Fio to your computer since…[Read more]

Do you only get that “extra junk” (as you described it) on the serial monitor when the Xbee is attached? It looks to me like you’ve got the Xbee radio on the same serial port as the board communication (the Arduino’s hardware serial port, which is pins 0 and 1), right? The Arduino board is talking to the PC at 57600 baud, but the Xbee has a…[Read more]

What kind of distance are you trying to cover with your radios? There are a variety of Xbee options that will work for short distances (several hundred meters), but there are also models for transmitting over a kilometer or more. There are different models for different regions of the world because of frequency regulations and other issues, so I…[Read more]
