Connect to Wi-Fi - First-Generation Devices

This guide will walk you through connecting your device to Wi-Fi. Before you connect your device to Wi-Fi, here is some important information to consider:

Firewall Requirements

• Does the web connection require users to enter information on any kind of captive portal/login page? If it does, the MAC address will need to be whitelisted. Send the MAC address and these firewall requirements to your IT support staff for assistance.
• Our WiFi devices only support 2.4GHz networks. These devices will not connect to 5GHz networks. If your network has both 2.4GHz and 5GHz network channels, you may need to have band steering disabled.
• Please note that our devices do not support 40MHz wide-band channels.
• Please check to ensure that IPv6 is disabled.
• While you’re investigating your network settings, it’s worth confirming that the respective port is open: TCP Port 5683 (CoAP), outbound.

Connect to Wi-Fi

Please note that before you can connect your device to Wi-Fi, the sensor must plugged in and the monitor must be in Listening Mode (fast blinking royal blue).

Getting Started:

1. Screw the Wi-Fi antenna onto the gold male adapter.
2. Plug the sensor into the correct port on the top of the monitor.
3. Plug the monitor in and power it on by sliding the switch into the up or on position.
4. When the monitor is turned on, it should be in Listening Mode (LED fast-blinking royal blue). If it is not, click here.

Connection Methods:

• Particle Application Method (iOS only)
• CLI Method (advanced configuration)

Particle Application Method (iOS only):

If you do not have access to an iPhone, do not use an Android, it will not work. You will need to use the CLI Method or contact customer support at StatTemp@gohcl.com

1. Open the App Store on your iOS device and download the Particle IoT application. The icon for the app is dark blue with an 8-point white star.
2. Once downloaded, open the Particle IoT application.
   1. During this process, it may ask to grant permission to use your location and to access other devices on your network. Select yes for all permissions.
3. Click 'GET STARTED'
4. Click 'Skip Authentication'
5. Click 'Yes'
6. Click the + sign on the top right.
7. Click 'Photon'.
8. Go to the iOS device Wi-Fi settings and connect to the available Photon-XXXXXX network.
9. Once connected, return to the Particle IoT application and click 'Ready'.
10. Select the network you are connecting to and enter your password.
11. If you are connecting to a hidden network:
    1. when prompted to select your Wi-Fi network, click the option at the bottom that says 'My network is not listed'.
    2. Type in the network name. Network names are case-sensitive, so be careful to type it in exactly as it appears.
    3. Type in the password
12. Click 'Connect'.

Your device will restart. The LED will fast blink green, then fast blink light blue, then slow blink light blue. That means your device is connected to Wi-Fi. It may also update if an update is available. The LED will blink magenta if it needs to be updated.

Using the CLI to connect to Wi-Fi (advanced configuration):

The CLI communicates directly with the Stat Temp monitor and can help with setting up Wi-Fi and upgrading/downgrading firmware.

1. Download the CLI here: https://docs.particle.io/tutorials/developer-tools/cli/
2. Under USING WINDOWS, click the link that says ‘Download the Windows CLI Installer' and run it on your computer. This process takes a couple of minutes. Make sure you grant all permissions needed to download.
3. Plug the sensor(s) into the Stat Temp monitor.
4. Plug the Stat Temp monitor into the computer's USB port with the provided MicroUSB cord.
5. When the installer is downloaded, open the Command Line Prompt in Windows. (search for CMD in the search bar next to your Windows menu).
6. Type in the Command Prompt: particle serial wifi
7. When it prompts ‘Should I scan for nearby WiFi networks?’ enter ‘n’ and hit enter.
8. SSID: type in the name of the network you are connecting to (this is case-sensitive)
9. It may prompt for:
10. Security type (Use arrow keys) – choose WPA2
11. Cipher type (Use arrow keys) – choose AES+TKIP
12. WiFi Password – enter the password for the network that you choose above

Done! Your device should now restart. – Your device will restart. The LED will fast blink green, then fast blink light blue, then slow blink light blue. That means your device is connected to Wi-Fi. It may also update if an update is available. The LED will blink magenta if it needs to be updated.

Listening Mode

To put the device into Listening Mode, follow these simple instructions.

1. Insert a paperclip into the bottom pinhole on the left side (above the LED) and hold. The LED will turn royal blue. Continue to hold the paperclip in the bottom pinhole.

The LED will stay royal blue or turn magenta.

2. If the LED stays royal blue:
   1. release the paper clip when the light starts to rapidly flash royal blue (about 8 seconds).
3. If the LED flashes magenta, immediately release the paperclip. The device will start flashing green.
   1. Reinsert the paper clip into the bottom pinhole and hold until it rapidly flashes blue then release the paper clip.  
   2. If the light turns yellow, you will need to reset the device and start over. To reset the device, push a paperclip into the top pinhole and release it.
