ESP8266: make erase_flash ESPPORT="PORT_NUMBER". You haven't provided much details on your implementation, but if assuming the standard ESP-IDF implementation then the WiFi credentials are stored in Flash on the default NVS partition named "nvs" ( overview ). You can easily perform an erase cycle on the entire partition which will erase everything stored in your device.Esp32 Clear Nvs. Get the time from a Network Time Protocol (NTP) time server Demonstrates use of UDP sendPacket and ReceivePacket For more on NTP time servers and the messages needed to alternatively, you can set up an NTP server on your local network and refer to it by IP address, rather than DNS name. There are NTP servers like pool.nvs_namespace esp32_nat nvs_set lock str -v 0. If you made a mistake and have lost all contact with the ESP you can still use the serial console to reconfigure it. All parameter settings are stored in NVS (non volatile storage), which is not erased by simple re-flashing the binaries. If you want to wipe it out, use "esptool.py -p /dev/ttyUSB0 ...2 Answers2. Show activity on this post. The ESP32 doesn't have an actual EEPROM; instead it uses some of its flash storage to mimic an EEPROM. The specs will depend on the specific SPI flash chip, but they're likely to be closer to 10,000 cycles than 100,000.Esp32 Clear Nvs. Get the time from a Network Time Protocol (NTP) time server Demonstrates use of UDP sendPacket and ReceivePacket For more on NTP time servers and the messages needed to alternatively, you can set up an NTP server on your local network and refer to it by IP address, rather than DNS name. This is a known problem of ESP32, and it may occur when the following conditions are satisfied at the same time. SoftAP channel on ESP32 and the connecting AP channel you specified are different. (The default channel of SoftAP is 1.) NVS had erased by erase_flash causes the connection data lost. The NVS partition has been moved.2 Answers2. Show activity on this post.

The information would be store in the NVS as the key. Now, ESP32 can be connected to the WiFi with the information read from the flash when it re-start.
