TRMNL supports multiple WiFi credential pairs, all of which is stored locally on your device and never sent to the cloud or your BYOS server clients.
If you've changed networks, or moved your TRMNL between locations, you might need to update the WiFi configuration.
Manually Enter Pairing Mode
With your TRMNL device already turned on, hold the boot button on the back of your TRMNL for 5-8 seconds, then let go and it should enter WiFi pairing mode. You can also try holding the button for 15-20 seconds if this shorter value doesn't work.
Set a Macro for Pairing Mode
If you anticipate frequent WiFi or location changes for your TRMNL, consider setting a special function so make your device enters WiFi pairing whenever you double-click on the boot button.
Default approach to Pairing Mode
If your device has become unresponsive, turn it off for 10 seconds to reset the buffer. Then turn it back on. If the network SSID is not found, it should re-enter pairing mode.
