RSSI being a relative value, is it valid to use this value provided by ESP8266 and ESP32 boards (WiFi.RSSI()) to compare wifi reception performance of these boards (all these boards use controllers from the same Espressif) ?

I would like to use an 16340 battery with the LILYGO® TTGO T-OI Plus ESP32-C3. Can anyone advise me which battery to select (capacity, make) ? there are so many vendors on AliExpress advertising multi thousand mAh devices, but many buyers have reported that is not true

Thank you so much ESP_Sprite and lbernstone.

When I compile a simple sketch that just invokes the WiFi lib, I obtain the following info: Sketch uses 637642 bytes (48%) of program storage space. Maximum is 1310720 bytes The maximum usable flash is actually 1310720 even if the board has 4MB If I compile a sketch that just invokes the Wifi+BLE, I...

I am moving from ESP8266 to M5Stack C3U Stamp board. I am using Arduino IDE 1.8.19. Is there any lightweight alternative to the WiFi lib ? The WiFi lib consumes lots of flash memory (~600kB) if one compares it to the ESP8366WiFi lib. Actually, I only need to connect to an AP by providing the SSID an...
