Hidden network / broadcast an ssid with OPTA

[wordbrda]

Hello!

I'm trying to connect my new OPTA to a hidden network, but every time I'm unsuccessful.
I tested with different programming, from Wi-Fi programming dedicated to OPTA to other Arduino boards, but none of them were successful.

On this same network, after it is not hidden, OPTA connects normally, but when it becomes hidden it loses its connection.

Can anyone help me with this ?

Hi @wordbrda. The Arduino developers are tracking the request to add support for connecting to hidden networks here:

Connectivity to hidden WiFi networks

If you have a GitHub account, you can subscribe to that thread to get notifications of any new developments related to this subject:

There is some related discussion here:

Arduino Giga R1 WiFi is unable to connect to a hidden wifi network

Hi, I recently started using the Arduino Giga R1 WiFi. I attempted to connect it to my hidden WiFi network, but it's not working. But it is getting connected to open WiFi networks. Kindly inform me if you have any possible solutions. This is the code I am trying #include <SPI.h> #include <WiFi.h> ///////please enter your sensitive data in the Secret tab/arduino_secrets.h char ssid[] = "ssid"; // your network SSID (name) char pass[] = "password"; // your network password (use for WP…

(the Opta uses the same "WiFi" library as the GIGA R1 WiFi board)

Thanks for the information, can I easily access the library to try to make any changes?

Are you using Arduino IDE or Arduino PLC IDE?

I am using Arduino IDE.

OK, great, then the file is at this path:

If you are using Linux:

/home/<username>/.arduino15/packages/arduino/hardware/mbed_opta/<version number>/libraries/WiFi/src/WiFi.cpp

(Where <username> is your Linux username and <version number> is the version number of the "Arduino Mbed OS Opta Boards" platform you have installed)

If you are using macOS:

/Users/<username>/Library/Arduino15/packages/arduino/hardware/mbed_opta/<version number>/libraries/WiFi/src/WiFi.cpp

(Where <username> is your macOS username and <version number> is the version number of the "Arduino Mbed OS Opta Boards" platform you have installed)

The Library folder is hidden by default. You can make it visible by pressing the Command+Shift+. keyboard shortcut.

If you are using Windows:

C:\Users\<username>\AppData\Local\Arduino15\packages\arduino\hardware\mbed_opta\<version number>\libraries\WiFi\src\WiFi.cpp

(Where <username> is your Windows username and <version number> is the version number of the "Arduino Mbed OS Opta Boards" platform you have installed)

If looking for it with your file manager or command line, note that the AppData folder is hidden by default. On Windows "File Explorer", you can make it visible by opening the "View" menu, then checking the box next to "☐ Hidden items".

Thank you, I got access to the library.
I'll try to make some changes to see if I can get any results, again thank you very much.

You are welcome. I'm glad if I was able to be of assistance.
