Wi-Fi & time

The badge can join a Wi-Fi network and use it to set its clock automatically. Both are handled from Tools → WiFi.

The Wi-Fi menu has four entries:

1. Connect / Disconnect (or No WiFi configured when nothing is saved yet)
2. WiFi Setup
3. Details
4. Sync Time

Setting up a network

Choose WiFi Setup to run the setup flow:

1. The badge scans for nearby networks and lists them, strongest signal first. Each entry shows the network name, a signal-strength indicator, and a padlock for secured networks. The scan times out after about 10 seconds.
2. Pick a network from the list, or choose + Add Manual to type a network name (SSID) by hand.
   • When adding manually, you also pick the encryption type: WPA2, WPA/WPA2, WPA3, WPA, Open, or WEP.
3. For a secured network, enter the password (up to 64 characters). Open networks skip this step.
4. Choose the IP mode:
   • DHCP (Auto) — the network assigns an address automatically.
   • Static IP — you enter the IP address, gateway and netmask yourself (each must be a valid IPv4 address; the default netmask is 255.255.255.0).
5. The badge saves the configuration and attempts to connect.

The saved network is remembered, so afterwards you can simply use Connect.

Connecting and disconnecting

• Connect brings Wi-Fi up using the saved configuration. The connect attempt times out after 15 seconds by default.
• Disconnect turns Wi-Fi off.

The Wi-Fi intent (on or off) is remembered across restarts, and a Wi-Fi indicator appears on the lock screen while connected.

Checking the connection

Details shows the current status:

• When connected: status, network name (SSID), MAC address, IP address and signal strength in dBm.
• When not connected but configured: the saved network name and whether it uses DHCP or a static IP.
• When nothing is configured: a “No WiFi configured” message.

Setting the time over the network (NTP)

Sync Time sets the badge clock from an internet time server (NTP).

• This step requires Wi-Fi. You need either an active connection or a saved network configuration. If the badge is not connected, it connects first.
• The badge queries pool.ntp.org and time.google.com, waiting up to about 10 seconds.
• On success the badge confirms the time was synced and marks its clock as set; on failure it reports a sync timeout.

Tip

You can also set the clock by hand with Settings → Set Date and Settings → Set Time. See Settings.

Why the clock matters

Time-based features depend on the badge having a correct clock. Keeping the time accurate — by syncing over NTP or setting it manually — ensures these features behave as expected.
