Learn how to request date and time from an NTP Server using the ESP32 with Arduino IDE. Getting date and time is useful in data logging projects to timestamp readings. To get time from an NTP Server, theESP32needs to have an Internet connection and you don’t need additional hardware (...
To obtain epoch time with ESP32 through the NTP server, we’ll follow the client-server model. Our ESP32 development board acts as the client and will connect to the widely accessible NTP server, pool.ntp.org, using UDP on port 123. Through this port, the server can communicate with the...
To get epoch/unix time with the ESP32, you can use the following functiongetTime(): // Function that gets current epoch timeunsignedlonggetTime(){time_tnow;structtmtimeinfo;if(!getLocalTime(&timeinfo)){//Serial.println("Failed to obtain time");return(0);}time(&now);returnnow;} This...
Both use an external oscillator, and the ESP32 receive the 50MHz RMII clock on GPIO0. Both use 3157 analog switch, to disconnect the oscillator at boot time, because the ESP32-GPIO0 is read at boot time. The difference between both versions is: with the WROOM version, the switching of...
The objective of this post is to explain how to perform a GET request over HTTPS using the Arduino core on the ESP32. The tests of this ESP32 tutorial were performed using a DFRobot’s ESP-WROOM-32 device integrated in a ESP32 FireBeetle board. Introduction The objective of this post ...
Our ESP32 Rest API server handles four different rest APIs. We will use the on() method on the server object to listen to the incoming HTTP requests. The server will receive a request on the following URLs: /temperature: This will return the current temperature in degree Celsius ...
ESP32 Xiaomi Hack - Get Data Wirelessly: Dear friends welcome to another Instructable! Today we are going to learn how to get the data that this Xiaomi Temperature and Humidity monitor transmits using the Bluetooth functionality of the ESP32 board. As y

(Wi-Fi, Bluetooth, low-level RF functions) that are distributed as closed-source precompiled libraries integrated into the firmware. There were some efforts to provide anopen-source stack for the BL602 chipbut it never went anywhere, and the ESP32 may become the first target with an open-...
Compared to ESP32-S3-EYE v2.1, ESP32-S3-EYE v2.2 has two changes in hardware: 1) marking on the main board,2) additional current limiting resistor on the main board; and one change in firmware: additional support for English wake-up word and commands. ...
