RAK5010

Overview

WisTrio NB-IoT Tracker Pro (RAK5010) is a tracker with integrated LTE CAT M1 & NB1, GPS, BLE, and sensors. It is built on the Quectel BG96 LTE CAT M1 & NB1 module, which has an integrated GPS receiver. The MCU running the board is a Nordic nRF52840 controller.

As it has both GPS and BLE it can be used for outdoor and indoor scenarios, where location-based services need be present.

The built-in sensors for RAK5010 are temperature and humidity sensor, motion sensor, pressure sensor, and light sensor. The extension IOs allow adding more sensors in addition to the on-board ones.

This board is particularly suitable to be used as a quick testing and prototyping tool for applications requiring NB-IoT connectivity. Application development supports the GCC environment.

Programming and Debugging

The RAK5010 board shall be connected to a Segger Embedded Debugger Unit J-Link OB. This provides a debug interface to the NRF52840 chip. You can use JLink to communicate with the NRF52840.

Flashing

  1. Download JLink from the Segger JLink Downloads Page 1. Go to the section “J-Link Software and Documentation Pack” and install the “J-Link Software and Documentation pack for Linux”. The application JLinkExe needs to be accessible from your path.

  2. Run your favorite terminal program to listen for output. Under Linux the terminal should be /dev/ttyACM0. For example:

    $ minicom -D /dev/ttyACM0 -o

    The -o option tells minicom not to send the modem initialization string. Connection should be configured as follows:

    • Speed: 115200

    • Data: 8 bits

    • Parity: None

    • Stop bits: 1

#. Connect the RAK5010 board to your host computer using the USB debug port. Then build and flash the Hello World application.

# From the root of the zephyr repository
west build -b rak5010_nrf52840 samples/hello_world
west flash

You should see “Hello World! rak5010_nrf52840” in your terminal.

Debugging

You can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b rak5010_nrf52840 samples/hello_world
west debug
