I followed all the instructions in the Network and Wifi wiki and downloaded and included all the libraries.
However when I go to run the Wifi Scan example it just prints the following to the Serial monitor.

Scrolled through the serial monitor output and also found these messages:

Two questions:
Did you update the firmware on RTL8720? The wiki specifically states you must do this first: https://wiki.seeedstudio.com/Wio-Terminal-Network-Overview/
Sometimes WIFI routers are configured to not broadcast their SSID. Is it possible your router is not broadcasting the SSID?
Hey Dennis_Mabrey,
Unsure what the problem is but I would try the next example in the Wiki that connects directly to the network by giving the SSID and the network password.
If that doesn’t work then I don’t know what to tell you.
Hi @ZebraWolf
It does seem like it’s the WiFi firmware is not uploaded properly to me. Can you re-upload the firmware to the WiFi Core again please. It should say successful if done correctly.
Well it looks like I goofed when doing the firmware install. I believe now after going through it a second time that I forgot to do the “erase” step before doing the download. Now the wifi scan is working perfectly.
Thank you Dennis_Mabrey and ansonhe97 for the help!
Glad to hear it is now working.
