It's has been well-known for twenty years that hiding your SSID does not give any advantage in security at all.

That why I said, I don't know why you'd want it.

A web search using "home router security" will show many sites that still
recommend it.

How does the bridge handle RI?
Is it possible to configure the serial signals for 'active high'?

Then they're giving wrong information. The SSID is just a string that's sent alongside the beacon every ~100 ms. The beacons are still sent (because without it, wifi won't work), they just don't have a name. Everything else is still inside, like your router's mac address (which is necessary for association).

I don't believe the UART's RI input is connected to an external pin via any mux path? You could use and read some GPIO for it though?

I seem to remember having seen that option on AVR microcontrollers, but not on the ESP8266.

- Sat Jan 06, 2018 7:03 am #72922 Thanks for your quick response. I understand about SSID - I just wanted to be sure for when I write instructions for users.

I want to use it with this...

to control legacy serial devices.

I'll breadboard and test next week.
