To program ESP32 so it can communicate with an Android phone using the Bluetooth protocol, you have to set up the ESP32 Bluetooth serial library. For that, you must have an Arduino IDE setup with an ESP32 board installed. After setting the ESP32 Bluetooth, you have to install the Bluetoo...
To erase the Flash Memory on an ESP32 using a CMD or Terminal window, your system should have the latest version of Python. If Python is not installed on your system, install it and proceed with the following instructions. You can download Python from its official website or install it di...
You can create files to save data on the ESP32 filesystem as you would do with a microSD card. The advantage is that you don’t need any extra hardware. However, it’s not appropriate for saving big amounts of data or for long-term datalogging applications and you’re limited to the...
In this manner, we can connect up to 8 LCDs to the same line. There is one more thing, the ESP32 takes 7 bit address for the I2C device. All the functions, which are included in the library of ESP32 will shift this address to the left by 1 bit, 0x27<<1, and the LSB here ...
Before installing ESP32 package in Arduino IDE, it’s crucial to ensure that you have the latest version of Arduino IDE. ESP32 has been known to have compatibility issues with previous versions of Arduino IDE. Therefore, we recommend deleting any old versions and installing the latest ones to...
The first step to install your ESP32 on Linux is to set up the Arduino IDE. Download the Arduino IDEfrom the Arduino websiteand then extract the provided ‘.tar.gz’ file into a directory on your PC. Open up a terminal window, CD to the Arduino directory you extracted to and run ‘...
