What better way to get acquainted with the Wio Terminal than a project! I saw the Dual Band WiFi Analyzer with Wio Terminal example and decided to follow it. It was a pretty smooth and fun process.

You start by setting up the Wio Terminal software, then you update the Wireless Core RTL8720 firmware and install all related libraries.

python3 ambd_flash_tool.py erase

python3 ambd_flash_tool.py flash

Then you install the Arduino_GFX Library. But that’s not as easy as the tutorial says. I kept getting a failure and missing files messages. I figured it was just some missing libraries, it’s like trying to install RPMs 10 years ago and solving dependencies. 🙂 This was a life saver. All the libraries you need to make it work. Make sure you Arduino IDE "Sketch" Menu -> "Include Library" -> "Add.ZIP Library" -> select downloaded ZIP file for each library.

For reference that’s these repos:

Seeed_Arduino_rpcWiFi 26 – master branch
Seeed_Arduino_rpcUnified 16 – master branch
Seeed_Arduino_mbedtls 31 – dev branch
Seeed_Arduino_FS 14 – master branch
Seeed_Arduino_SFUD 12 – master branch

After those are installed, upload and it’s done!
