WiFi.scan() SSID is returning empty

Firmware
1

Hello,
I am using the example code mentioned here to display the WiFi networks.

https://docs.particle.io/reference/firmware/photon/#scan-

For some WiFi networks, SSID is returned as NULL. Is it because there is a hidden network in the air?

Thanks
Dheeraj

Suggest you run an independent WIFi analyser on a smartphone to compare results.
