Device Simulator 
Command line utility for simulating a device connecting to and pairing with nRFcloud.com.
CLI Usage
Installation
mkdir simulator
cd simulator
npm init -y
npm i --save @nrfcloud/device-simulator
Usage
npx @nrfcloud/device-simulator \
-c <configuration file from nrfcloud-cli> \
-n <file with GPS NMEA sentences> \
-a <file with accelerometer recording> \
-t <file with thermometer recording> \
-d <file with device info>
Example:
npx @nrfcloud/device-simulator \
-c my-device.json \
-n /tmp/nmea-recording.txt \
-a __tests__/sensors/accelerometer-recording.txt \
-t __tests__/sensors/thermometer-recording.txt \
-d __tests__/sensors/device-info-recording.txt
Sensor Data
NMEA sentences
A GPS recording of NMEA sentences can be found here.
If you have curl installed:
curl -L -o /tmp/nmea-recording.txt "https://drive.google.com/uc?export=download&id=0BxDUQnmvFeMNOXM1ZmFFNHZZU2s"
If you want to make your own GPS data, head over to https://nmeagen.org. The "Multi-point line" seems to work best. Lay some points and then click the "Generate NMEA file" button.
Accelerometer samples
An accelerometer recording can be found here.
Thermometer samples
A thermometer recording can be found here here.
Device samples
A device info sample can be found here here.
Creating Devices and Certs
Use STAGE=dev STACK=dev node scripts/register-simulator.js to create a new certificate.

Device configuration
To create a device configuration use nrfcloud-cli.
Example usage for adding a device to nRF Cloud (this is not associating a device with a tenant):
npx dist/cli.js device-register -t nsrn:devices:types/device/nordicsemi/nRF91/PCA10074/gpsFlipDemo/0 <your device id>
