Updates are performed via the BLE interface of the WA2000. A single update file in our new .TCU (Tibbo Composite Uncompressed) format can update the TiOS firmware, attached Tibbo BASIC/C application binary, and even the internal firmware and Monitor/Loader of the WA2000!

The app automatically discovers nearby devices that are ready for an OTA update. It also makes sure that the .TCU file you are preparing to send is compatible with the selected target device.
