PCTEL WSC-1450

The PCTEL Wireless Sensor Core (WSC) is a versatile Industrial IoT product line that offers multiple radio connectivity options including cellular, LoRa, Bluetooth 5, NFC as well as 802.15.4 support.

In addition to several radios, the PCTEL WSC includes several sensors to monitor a variety of physical conditions. These sensors can detect gas, air quality, temperature, relative humidity, acceleration, angular rate of change, magnetic field, range, and sound. For solution optimization, the PCTEL WSC can be ordered with a subset of radios and sensors.

Build instructions

Configure your build environment according to the Adafruit instructions. To build circuitpython for WSC-1450 do:

cd ports/nrf make BOARD=pctel_wsc_1450

This will create a number of firmware files in the build-pctel_wsc_1450 directory.

Installing

The WSC-1450 do not feature an Adafruit-provided bootloader (supporting niceties like UF2 flashing). Instead, WSC-1450 uses DAPLink. DAPLink handles everything from debugging to programming the device, as well as the boot sequence.

1. Connect the WSC-1450 dev kit using a USB cable to the DHD USB port. This will power up the board and open a file browser showing the contents of the target. (DAPlink magic)
2. Copy the newly built firmware to the WSC-1450 target using drag-n-drop or other method. The file to upload is circuitpython/ports/nrf/build-pctel_wsc_1450/firmware.combined.hex
3. Wait for the file to upload.
4. Install is complete. Reset the board.

Running

Connect an additional USB cable to the Target USB port on the development board and open a terminal like screen on Mac or TeraTerm on Windows. Serial settings are 115200,n,8,1.

Don't forget to install/update the supporting python libraries.

Happy hacking.
