Update firmware

Firmware updates use a direct USB connection. Update one device at a time and keep it connected until the app says the update is complete.
Check the firmware versions
Open Setting → About.
Find the Firmware card. It shows the current and latest versions and whether connected devices are behind.
Click Check Firmware Updates and wait for the version check to finish.
Click Update Firmware.
Update a Tracker
In the upgrade window, choose Tracker Firmware.
Connect the Tracker you want to update directly to the PC with a USB data cable. The app reads its Tracker ID and selects its COM port.
Check that the selected port names the Tracker ID you intend to update. If it does not appear, click Refresh after connecting it.
Click Start Upgrade.
Keep the Tracker connected. Do not unplug it or disconnect the USB cable while the progress screen is open.
When the app says Upgrade Complete!, disconnect and reconnect the Tracker, as the message instructs.

Update the 2.4G Dongle

Keep the Excap Link 2.4G Dongle connected to the PC. The app selects its COM port automatically.

If the port is missing or busy
For a Tracker update, connect the Tracker directly to the PC, then click Refresh. For a Dongle update, check that the Excap Link Dongle is connected.
Close any other program that may be using the USB serial port, such as a serial monitor, Arduino IDE, or another Excap instance. Then click Refresh.
If the port still does not appear, open Setting → About and check 2.4G Dongle Driver under Local environment check. The driver is included with Excap; you do not need a separate driver download. If the app says it is not detected, use its Install action, then click Refresh in the firmware window.
If the error says no firmware URL is available, click Check Firmware Updates again. If it still fails, stop and contact support with the error message.
The update window disables interruption while firmware is being written. Wait for the result. If the update fails, reconnect the device and retry only after the app shows the device port again.
