mangOH Red hardware design is fully open source with BoM, schematics (PDF an Allegro/OrCAD), PCB Layout (Intercept Pantheon), Gerber, and mechanical files available for download in the resources section, where you’ll also find other documentation and getting started guides for users and developers.  The CF3 modules run Legato Linux developed by Sierra Wireless, and open source with the source code on Github. Code specific to MangOH Red + WP8548 was also upstreamed in Linux 4.10.

The company also offers Sierra Wireless Smart SIM with up to 100 MB free data, but you can use the board any commercially available SIM car. The board also supports AirVantage IoT Platform to create, deploy and manage solutions in the cloud.

MangOH Red board can be purchased as a bareboard, but most people will probably want to get a Starter Kit with MangOH Red plus Air Prime WP8548, WP7502 or WP7504 sold on Digikey. I’m very confused by the price list, as $99 is shown for both the bare board, and kits including the board and a CF3 module. So I’ll assume $99 is for mangOH board only, and you’d likely have to pay $200+ for a board plus a CF3 module with the total price depending on the selected module. You may find additional details on MangOH Red product page.

Review of Wio Tracker with GPS, Bluetooth 3.0 and GSM Connectivity

June 11th, 2017 No comments

Wio GPS – also called Wio Tracker – is an Arduino compatible board based on Microchip Atmel SAMD21 MCU with GPS, Bluetooth, GSM/GPRS connectivity, as well as several Grove connectors to connect sensors and modules for your IoT project. SeeedStudio sent me a sample for evaluation, so I’ve tested it, and reported my experience below by testing some of the Arduino sketches.

Wio Tracker Unboxing

All I got in the package was Wio GPS tracker v1.1 board. The top includes the Atmel MCU, an RGB LED, a microphone and 3.5mm AUX jack to make phone calls, a user and power button, a micro USB port for power and programming, a small 2-pin connector for a battery, and 6 Grove connectors for digital, serial, I2C and analog modules.

The other side of the board comes with Quectel MC20 module that handles Bluetooth, GPS and GSM, a dual use micro SD card and nano SIM slot, and the GPS, 2G, and Bluetooth antennas. We can also see -/+ footprints close to connect speakers close to the OSHW logo.

Getting Started with Wio GPS Tracker with Arduino IDE

I’ve been following Wio GPS Board Wiki for this part of the review, and as we’ll soon discovered I’ve had a rather mixed experience.

First, you’ll need a micro USB to USB cable to connect the board to Windows/Linux/Mac computer. This is the kernel output I got from Ubuntu 16.04:

After installing Arduino IDE for your operating system, we can add Seeduino boards to the IDE, by going to File->Preferences and pasting the link https://raw.githubusercontent.com/Seeed-Studio/Seeed_Platform/master/package_seeeduino_boards_index.json into Additional Boards Manager URL field, and clicking OK.Now go to Tools->Boards->Boards Manager search for wio, and install Seeduino SAMD by Seeed Studio.

You can also install Adafruit Neopixel by going to to Sketch->Manage Libraries->Include Library, or importing the zip file. After that point, I decided to check whether I could find “Wio Tracker” in the list of boards as indicated in the Wiki, but there was no such board so I selected Wio GPS Board, and selected port /dev/ttyACM0 (Wio GPS Board) port.

Then I went to check for sample sketches, and found some in Examples->Seeed_Wio_GPS_Board for the all key features of the board. So I tried a bunch of them including RGB_LED, Bluetooth, GNSS (GPS), and GSM (Send SMS), and only the Bluetooth sample would work.

Click to Enlarge

By I went back to the Wiki, and found out I add to import Wio Tracker library too, which I did, and I had another very similar sets of samples for MC20_GPS_Traker-master.

I’m not exactly sure we have two separate sets of nearly identical samples, but let’s see if I have more like with samples in MC20_GPS_Tracker-master folder.

Blink.ino is supposed to blink the RGB using blue color:

I could upload the program to the board with the following warning messages:

The RGB LED did not work. So I tried to remove Adafruit Neopixel library, same results. Finally I checked schematics to confirm the RGB LED is indeed connected to D10, and inserted some println debug code to make sure the program is running properly. Everything seems right, but the RGB LED would not blink. I’ve contacted the company, but unsurprinsgly they don’t work during the week-end.

Let’s move on with BT_CLientHandle.ino sketch that should allow us to pair the board with your phone. The code is relatively simple for this task:

I could see QUECTEL-BT with my Android phone, and had no problem to pair the board.

The serial output with pairing, and disconnecting events shows some of the AT commands used:

I also tried to connect a speaker to the AUX port of the board to see if I could use it as Bluetooth speaker, but it did not work, so some more code and a different Bluetooth audio profile (not HF_PROFILE) are likely required. All I could hear was dial-up modem sounds from the speakers. But still, we can tick this Bluetooth test as success.

Time for a GPS test. GNSS_Show_Coordinate.ino sketch is supposed to  output latitude and longitude to the serial console, and again the code to achieve this is still fairly simple:

But all I got in the serial output was the following:

With +CREG: 0,0 shown over and over. We can find the different AT Command sets (and EAGLE schematics) in the resources directory in Github. One of the document reports that AT+CREG? is a read command to retrieve network registration status, and the two numbers referred as <n> and <stat> are set to 0,0 meaning that:

  1. Disable network registration unsolicited result code
  2. Not registered, ME is not currently searching a new network to register on

I firstly did the test indoors, and although previously I could get a signal indoors with NavSpark mini board, I still went outside in case it was a signal problem, but the result was just the same. So maybe the program is stuck somewhere because I had not inserted a SIM card yet. Since I was not sure whether my operator still supported 2G, I forced my Android phone to use 2G, and the phone did get a signal using “E” instead of the usual 3G, and I could send an SMS and make a phone call over 2G network (I think).

So I took out the SIM card from my phone, and …. I could not insert right away simply because my SIM card was cut out as a micro SIM, but the board requires a nano SIM. Luckily, I purchased nano/micro SIM card adapters a while ago as I knew sooner or later I would have this little first world problem. You can find those for less than $1 on eBay, so even if you don’t need them right now, it might be a good idea to get some.

Once I cut out my SIM card so that it fits into the micro SIM to nano SIM adapter that I will need to use when I put back the SIM card into my smartphone, I inserted  the nano SIM and a micro SD card at the same time, as the picture below shows with the white band right above the 4GB micro SD card being the nano SIM card. I did not know they made those, as I’ve only seen shared slots in the past.

I reran the GPS sample program, and the serial output changes a bit, but still no longitude and latitude info:

+QGNSSC:1 means the GNSS module is powered on so that’s good news I guess.

+CREG: 0,2 means the SIM card is registered, and in home network, but then it will switch to +CREG:0,5 meaning the SIM card is registered and roaming. Not really re-assuring.

They also have a more complex sample called GNSS_Google_KML.ino, that will get coordinate display them in OLED display attached to the board, and save data into a gps.txt into the SD card with raw longitude and latitude data that can be inserted into a Google KML file. A GoogleMapDemo.ino sketch will upload your coordinates to ziladuo.com website. That’s provided it works of course… and considering the simplest sample GNSS would not work. I gave up on GPS/GNSS tests.

Last try was with the GSM function with the send SMS sample (MC20_SMSSend.ino) that will send “Hello MC20!!” message to the phone number of your choice”. Again it’s very easy to program:

But sadly I could not send an SMS, as the function waitForNetworkRegister failed:

I had to end my testing there. I could not remove the nano SIM card with my hands, and I had to use a pair  tweezers to get it out by pushing those the small holes on top of the slot mechanism.

So overall my experience with the board was quite catastrophic with only Bluetooth working,  and GPS, 2G GSM, and even the RGB LED sample all failing. I also often had trouble uploading the code to the board with messages like:

or (even after having close to the serial terminal for a while):

So I often had to re-try and re-try to successfully upload the code to the board. I’m sure there must be an explanation for all the issues I had. I can see they tested it in Windows, but I’m using Ubuntu 16.04, so maybe that could be one reason?

Having said that, if the board actually worked, I really like what SeeedStudio has done, as it looks really easy to program the board with GPS, Bluetooth, or 2G data, SMS, calls, and you can add Grove Sensors to make pretty more advanced IoT projects. The company also provides a more practical sample with their “Wild Adventure Tracker” demo reporting sending GPS coordinates over SMS when a shock occurs. The source code on Github with a video showing the results below.

The company is also working on a 4G version, and I’ll probably have a chance to give it another try once it is released. If you are interested in Wio GPS Tracker board, you can pre-order it for $24.95 including all three antennas.

8Power Vibration Energy Harvesting Technology Powers Batteryless LPWAN GPS Trackers, MEMS Sensors

May 23rd, 2017 No comments

While IoT products usually promises one to 10 years battery life, they will be several billions of them, and ARM’s CEO even forecast one trillion IoT devices in the next 20 years. Recharging batteries at home may be fine, but imagine having to recharge or replace batteries on top of electric poles, inside walls, in remote locations, and other hard to reach places, considerable resources would have to be deployed just to replace or recharge battery every year or whenever the battery is close to being depleted.  That’s why work on energy harvesting technology for batteryless devices may be so important, and 8Power is one of the companies working in the field through their vibration energy harvesting technology that is said to harvest up to 10x the power of competing devices under comparable condition thanks to the use of parametric resonance phenomenon.

8Power LTE NB-IoT GPS Tracker (Left) and MEMS Sensor (Right)

The company has recently announced their Track 100 family of LPWAN GPS tracker, such as Track 100XL relying on LTE NB-IoT, but they also have models supporting LTE Cat M1 and LoRaWAN. The IP67 devices include vibration energy harvesting technology, as well as optionally a solar panel. The company also provides a “secure cloud hosted data platform to provide dashboards, analytics, device management, security and application API access to manage fleets of devices”. There’s no battery, and no need for (battery related) maintenance. Track 100 trackers are powered through the vibration generated by trucks, trains, or other vehicles.

The company is also working on integrating the technology into MEMS sensors that consume very little power (10 mW) in continuous operations. Beside leveraging vibrations from the transportation industry, and 8Power technology can also generate power from vibrations from  infrastructure (bridges, embankments, transmission lines) or machinery (high-power motors and rotating equipment), and the technology has already been validated through a experiment to monitor the structure of an older bridge in Scotland.

The company showcased their technology and latest products at IDTechEx 2017.

MatchCore

Both models can be programmed using Dialog DA1468X SDK, a community has been setup, as well as a developer’s blog, but so far I’ve been pretty quite, as the company works on completing development. There’s very little info about MatchModule , which will be a 25x25mm LoRa module that can be integrated into your own project. The only info I’ve got about is in the table below.

The MatchBox gateway should sell for around $299, while MatchStick and MatchCore should go for $28 and $16 respectively, I assume in their minimal configuration, as final price will depend on the choice of sensors.

There are three models of the kit for sale, Asset Tracker 2G for $109, as well as Asset Tracker 3G (America/Australia) and Asset Tracker 3G (Europe/Asia/Africa) both going for $129. Particles kits will provide much more flexibility than the 3G + GPS tracker kits available on Aliexpress for $70 and up, and should be much easier to get started with then rolling your own with Orange Pi-2G IoT board, a cheap GPS modules such as NavSpark mini, plus battery and case.
