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!
Detailed notes on which ESP32 ethernet PHY options are supported by the most recent ESP32 Arduino releases and ESP-IDF.
ESP32 supports Wi-Fi, ethernet, PPPoS modem and other custom networking interfaces. Using esp_netif, you can search network interfaces.
ESP32 I2C repeated start or restart condition can be generated using the ESP-IDF I2C driver library. Here is how, with example code.
This article illustrates an easy way to sync ESP32 NTP and DS3231 RTC time so that ESP32 can use the RTC chip seamlessly in an application.
We troubleshoot a situation where the ESP32 cannot save JSON file to an SD card. The program in question is based on the ESP-IDF.
The ESP-IDF contains functions for enabling Base64 encoding and decoding on ESP32. The encoding and decoding functions are actually built into the ESP32 ROM. The functions are accessible by using …
