The ESP32 comes not only with Wi-Fi but also with Bluetooth and Bluetooth Low Energy (BLE). This post is a quick introduction to BLE with the ESP32. First, we’ll explore what’s BLE and what it can be used for, and then we’ll take a look at some examples with the ESP32 usin...
Some older Arduino boards and compatibles do not automatically interrupt the running sketch to initiate upload. In this case, you need to press the Reset buttonon the board just after the software reports that it is done compiling (when you see the message about the size of the sketch). It...
Just above the processor is the reset button. This allows you to restart your program. This is important to know because the controller saves any program uploaded to it. So, if you write a program for your controller that is made to blink an LED on or off, it will begin running that ...
Sometimes the uploader fails to reset the board to start the bootloader. If you see the firmware is compiled and the led doesn‘t start flashing within 5 seconds, press the reset button on the board. Often this helps. Sometimes you will get a fsync error message from the uploader. Unplug...
