Building a sensor node

We are now ready to start building our Android-controlled sensor node using the ESP32. In this section, we are going to build the sensor node. This will require us to do the following:

1. Install MicroPython on the ESP32.
2. Set up the sensor node as a Wi-Fi access point.
3. Install uasyncio.
4. Set up an Anaconda environment.
5. Write your application code.

There's a fair amount of work to do, so let's get started!

Installing MicroPython on the ESP32

The first step to getting our project underway is to install MicroPython on the ESP32 development. We saw in Chapter 5, Customizing the MicroPython Kernel Start Up Code, how we can get into the MicroPython kernel, customize it, and then rebuild the kernel...
