ESP32 DevKit C V4 - very weak WiFi signal
Posted: Mon Dec 06, 2021 3:37 pm
I am trying to use an ESP32 DevKit C V4 board with WROVER-B module, however the wifi signal is extremely weak. When in station mode, scanning returns only two access points (there are many more), and the strength of the signal from my router is -70 dBm when the board is next to the router.
When I place the board in the next room it cannot connect at all. I tried both stable and nightly MP builds; no difference. Is there any parameter which is under user control and can be tuned in order to increase the sensitivity of the device?
