Hi, I'm currently trying to implement indoor positioning system using 4 ESP32 microcontrollers where one board is a 'master' and other three are 'slaves'. The slaves are configured as AP, so I can use 'HTTP_GET' request from 'master' to get the needed data from 'slave' nodes. So far so good.. But th...

ESP-IDF supports getting back CSI information, which means you can figure out things wrt the different phase groups. I'm not sure if anyone already fleshed it out into a fully-functional positioning algorithm or what the precision of that would be, but that is another avenue of investigation you co...

Hello, I did not know where to ask this question, therefore I came here. Recently I bought multiple ESP32 devices like these: https://www.ebay.com/itm/WEMOS-ESP32-WiFi-Bluetooth-18650-Battery-0-96-inch-OLED-Development-CP2102/182945986004?hash=item2a986e35d4:m:mfz8ReGq0VPAXInFCXYkTKw&frcectupt=true ...
