Wio LTE Cat.1

Wio Tracker (Wireless Input Output) is an open source gateway which enable faster IoT GPS solutions. It is Arduino and Grove compatible development boards that helps you track nearly any moving thing on the planet and then upload that data wirelessly. The Wio LTE is the LTE version of Wio Tracker, so now we’ve got 2 versions of Wio Tracker and the LTE (4G) version will make some differences.

There are three main updates comparing the Wio LTE to the 2G version. Firstly, from its name we know that the Wio LTE supports LTE (4G) communication which is much faster and popular than 2G. Secondly, the Wio LTE supports in total 4 different GNSS – GPS, Beidou, GLONSS and Galileo, the QZSS is also supported as bonus. With more GNSS support, positioning will be more accurate. Thirdly, the Wio LTE‘s MCU is upgraded to STM32, which is based on Cortex-M4, makes the Wio LTE 5 times faster than the 2G version. What’s more, the flash and RAM have also been raised to 1Mbytes and 192+4k bytes.

Apart from the three main updates, the LTE version is almost the same as the 2G version. If your project is using the 2G version, it would be very easy to update to the LTE version because we have prepared transplantable and expansible AT command library. The Arduino and Grove compatibility allows for quicker development through numerous libraries and a supportive community. The GPS library which will be available with the board is not just limited to Arduino – it can function just as well if you chose to develop in C/C++. With the onboard 6 Grove connections, developers can create any combination of our 180+ sensors and actuators to build project and solve any problem. Simplifying the prototyping and development phase is our goal.

The Wio LTE is well suited for outdoor projects where the device can connect to the GPS satellites and provide a real-time location of the item it is attached to. The LTE provides a wide bandwidth which allows much faster interaction between the user and device. If you are going to build projects like a bicycle sharing service, tracking pets or livestock, locating a vehicle, or even keeping track of a child, the Wio LTE is the best solution.

Warning

Please always plug 3.7V Lipo battery in case USB power supply is not sufficient.

Wio Lte v1.3 Release Notes

Since the launch of this product, we have received a lot of user feedback and suggestions. We decided to further improve this product based on user feedback, so here you see, the Wio Lte v1.3 comes out.

We made some changes in the power circuit:

  • Change the PMIC (Power manage IC) into MP2617, which is more stable.
  • Remove the DC-DC Module which supplies for the Lte Module, instead, in this version we power the Lte Module by the main circuit or the Lipo battery.
  • Add two 100uf capacitors to make the power more stable.

As you can see in the pictures below.

                  v1.3                                  v1.0

As the power circuit changes, the logic of the power indicator has also changed.

LED Statues Battery Statues

LED off Charging finished
LED Blinking Battery error.(Including no battery statues)

What's more, the Reset Key logic changed as well.

Operation Rest Range
Hold the reset button for a short time(within 2 seconds) MCU reset/ Lte Module will not reset
Hold the reset button for a short time(More than 10 seconds) The hole board will reset

Tip

Use Grove modules to expand your application. There are 6 Grove connects on board. If this is your first time to hear about Grove, please put had on Grove System for more details. In brief, Groves is hundreds of sensor that in standard style, which is consist of sensors, actuators, displays as well as communication.

Hardware Overview

Tip

If you want to use the on-board Grove connector, please use digitalWrite(B10, HIGH) to open 3V3_B. except D38 power on by default. Otherwise you can't provide power to Grove modules.

EC21 Module

EC21 contains 9 variants: EC21-E, EC21-A, EC21-V, EC21-AUT, EC21-AUV, EC21-AU, EC21-KL, EC21-J and EC21-CEL. This makes it backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can easily migrate from LTE to 2G or 3G networks.

And EC21-A is what we are using in WIO Tracker - LTE, which supports AT&T and T-mobile sim card. If you want to customize EC21 Module for other region, feel free to email us: fae@seeed.cc

Getting Started

Install USB driver

  • Windows Users: Most versions of Windows won't automatically load the built-in driver for USB com ports. You'll have to download ST's USB driver STM32 Virtual COM Port Driver.

  • Mac OS X and Chromebook Users: The board will just plug in and work, without drivers!

Change DFU driver

For windows users:

  • Step 1. Press and hold BOOT button and connect to computer you will see STM32 Device in DFU Mode at device manager as below.

  • Step 2. This says that you need to use zadig_xx.exe to change DFU driver from STTub30 to WinUSB as below. If we can't see any info on the Zadig, please click Options→ List All Devices, then select STM32 Virtual COM Ports.

  • Step 3. You will see the "STMicroelectronics Virtual COM Port" on device manager as below.

FAQ

Q1: We fail to use Arduino IDE to download the program and see below error info at bottom of Arduino IDE.

A3: It is a bug. When using Arduino serial port to print info, the Arduino IDE remembers the serial port number. So there is no serial port available for downloading new program. We can reboot the Arduino IDE to solve the issue as temporary solution. For the preventive solution, please use other COM monitor software, such as SSCOM. Please make sure we see the processing bar during program downloading. Or else, we will see below info and the program is not downloaded.

Sketch uses 23068 bytes (2%) of program storage space. Maximum is 1048576 bytes.
Global variables use 13864 bytes of dynamic memory.
