Re: How do I list the RSSI (strength) of the Wi-Fi SSID I'm connected to?

I gather by the lack of response and also by some Googling around that this is not possible. I'll just do it as I proposed: Scan all networks and pull out my SSID. Where there are multiple matches I'll use the strongest one. I may do a scan at boot up and cache the results then refer back to them as...

How do I list the RSSI (strength) of the Wi-Fi SSID I'm connected to?

I've got a successful connection to my router using STA mode. How do I list the RSSI strength of my connection? I had thought to do another scan and list out the RSSI from there, but that's slow. (Speed is important; I'm building a web GUI for a product to sell.) Further, sometimes there are multipl...

Re: So you want to use the UART...

Right. So is that circuit required when the ESP will be listening for a command? I wouldn't think so since it's on the TX line but I want to confirm.

Re: So you want to use the UART...

[quote="pythoncoder"]The circuit is to ensure that the logic levels supplied to the ESP8266 don't exceed 3.3V.[/quote]

Hmm? Per the opening post, the circuit is to provide a non-blocking read. My question is whether it's required to send data into the ESP from another device such as a Pi.

In my case a Pi will send the 's' command to a listening ESP.
