Make an accurate, low power, cloud-connected ESP32 decibel meter using any ESP32 devkit, Arduino IDE and ThingsBoard. Includes demoArduino sketch.
Using ethernet with ESP32 is very easy, thanks to the built-in RMII PHY. In this article, a simple ESP32 ethernet example is outlined.
Using the built-in GPS, ESP32 Gateway can obtain a fix on its current location and also acquire current time. This makes IoT asset tracking easier.
The ESP32 crashes on esp_netif_internal_dhcpc_cb() when being used as a NAT router with cellular modem and Wi-Fi or ethernet – SOLVED!
