Laird Connectivity Pinnacle 100 DVK

Overview

The Pinnacle™ 100 cellular modem seamlessly incorporates a powerful Cortex M4F controller, full Bluetooth 5 and LTE-M/NB-IoT capabilities – all with full regulatory certifications and LTE carrier approvals. The Pinnacle 100 also delivers complete antenna flexibility, with pre-integrated internal or external antenna options such as the Revie Flex family of LTE and NB-IoT internal antennas.

Develop your application directly on the M4F controller using Zephyr RTOS to cut BOM costs and power consumption. Take advantage of the Zephyr community, Laird Connectivity’s sample code (cellular, Bluetooth) and hardware interfaces, or use our hosted mode AT commands set firmware.

Extremely power conscious, the Pinnacle 100 is ideal for battery-powered devices operating at the edge of your IoT networks, seamlessly bridging the cellular WAN to BLE. It’s never been easier to bridge wireless Bluetooth 5 sensor data to cloud services like AWS IoT over a low-power LTE connection.

More information about the board can be found at the Pinnacle 100 website 1.

Programming and Debugging

Applications for the pinnacle_100_dvk board configuration can be built and flashed in the usual way. (see Building an Application and Run an Application for more details)

Flashing

Follow the instructions in the Nordic nRF5x Segger J-Link page to install and configure all the necessary software. Further information can be found in Flashing. Then build and flash applications as usual (see Building an Application and Run an Application for more details).

Here is an example for the Hello World application.

First, run your favorite terminal program to listen for output.

Note

On the Pinnacle 100 development board, the FTDI USB should be used to access the UART console.

$ minicom -D <tty_device> -b 115200

Replace <tty_device> with the port where the board Pinnacle 100 DVK can be found. For example, under Linux, /dev/ttyUSB0.

Then build and flash the application in the usual way.

# From the root of the zephyr repository
west build -b pinnacle_100_dvk samples/hello_world
west flash

Debugging

Refer to the Nordic nRF5x Segger J-Link page to learn about debugging Nordic boards with a Segger IC.

Software

Pinnacle 100 Out-of-Box Demo Software

The Pinnacle 100 development kit ships with an out of the box software demo. Check out the Pinnacle 100 OOB Demo 4 source code and documentation.

Sample Applications

Pinnacle 100 Sample Applications 5 are available.

Testing Bluetooth on the Pinnacle 100 DVK

Many of the Bluetooth examples will work on the Pinnacle 100 DVK. Try them out:

Testing the LEDs and buttons in the Pinnacle 100 DVK

There are 2 samples that allow you to test that the buttons (switches) and LEDs on the board are working properly with Zephyr:

samples/basic/blinky
samples/basic/button

You can build and flash the examples to make sure Zephyr is running correctly on your board. The button and LED definitions can be found in boards/arm/pinnacle_100_dvk/pinnacle_100_dvk.dts.

Overlay file naming

The file has to be named <board>.overlay and placed in the app main directory to be picked up automatically by the build system.

See Set devicetree overlays for further details.

Selecting the pins

To select the pin numbers for tx-pin and rx-pin:

tx-pin = <pin_no>

Open the nRF52840 Product Specification 2, chapter 7 ‘Hardware and Layout’. In the table 7.1.1 ‘aQFN73 ball assignments’ select the pins marked ‘General purpose I/O’. Note that pins marked as ‘low frequency I/O only’ can only be used in under-10KHz applications. They are not suitable for 115200 speed of UART.

Translate the ‘Pin’ into number for devicetree by using the following formula:

pin_no = b\*32 + a

where a and b are from the Pin value in the table (Pb.a). For example, for P0.1, pin_no = 1 and for P1.0, pin_no = 32.
