# PCTEL WSC-1450
2+
3+
The PCTEL Wireless Sensor Core (WSC) is a versatile Industrial IoT product line
4+
that offers multiple radio connectivity options including cellular, LoRa,
5+
Bluetooth 5, NFC as well as 802.15.4 support.
6+
7+
In addition to several radios, the PCTEL WSC includes several sensors to
8+
monitor a variety of physical conditions. These sensors can detect gas, air
9+
quality, temperature, relative humidity, acceleration, angular rate of change,
10+
magnetic field, range, and sound. For solution optimization, the PCTEL WSC can
11+
be ordered with a subset of radios and sensors.
12+

# Build instructions
17+
18+
Configure your build enviroment according to the Adafruit instructions. To
19+
build circuitpython for WSC-1450 do:
20+
21+
cd ports/nrf make BOARD=pctel_wsc_1450
22+
23+
This will create a number of firmware files in the `build-pctel_wsc_1450`
24+
directory.
25+
26+
27+
# Installing
28+
29+
The WSC-1450 do not feature an Adafruit-provided bootloader (supporting
30+
niceties like UF2 flashing). Instead, WSC-1450 uses DAPLink. DAPLink handles
31+
everything from debugging to programming the device, as well as the boot
32+
sequence.
33+
34+
1. Connect the WSC-1450 dev kit unsing a USB cable to the `DHD USB` port. This
35+
will power up the board and open a file browser showing the contents of the
36+
target. (DAPlink magic)
37+
2. Copy the newly built firmware to the WSC-1450 target using drag-n-drop or
38+
other method. The file to upload is
39+
`circuitpython/ports/nrf/build-pctel_wsc_1450/firmware.combined.hex`
40+
3. Wait for the file to upload.
41+
4. Install is complete. Reset the board.
42+
43+
# Running
44+
45+
Connect an additional USB cable to the `Target USB` port on the development
46+
board and open a terminal like `screen` on Mac or `TeraTerm` on Windows. Serial
47+
settings are 115200,n,8,1.
48+
49+
Don't forget to install/update the supporting python libraries.
50+
51+
Happy hacking.
