BLE Scan and obtain RSSI

[madscientist_42]

Don't trust the RSSI values, it is mostly complete nonsense

It is? What basis do you have for this? Did you do the requisite analysis with precision equipment and arrived at this? If not...how can you claim it's nonsense?

Cool. Had Neil put that in as basis for remark (Since it's his issue he reported...and not all of us know all the bug issues in the forums...)...I'd have not questioned him. Useful to know that it's busted.

I was using esp-idf v1.0, I believe the BT rssi has stabilized but still has some fluctuation. v1.0 was really bad compared to the current version.

Some (ESP32/Arduino) code is here showing a scan and getting the mac address and RSSI. Described in the article here.

Hey everyone,

I just started working with the ESP32 and I just want to program a simple bluetooth scan with Arduino IDE to get the mac and rssi. But I dont really know, wich part of this code posted by torntrousers is important for that. Hope someone can help.
