Nodemcu esp32s v1.1 bluetooth

[9acca9]

Hi.

First time using that device.

Im a beginner coder that already made some projects with Python in a Raspberry pi but I never use Micropython (also never use a esp32)
I want to make a physical chess board that will work with reed switches and magnets (there is a lot of this works in the internet)

I buy the Nodemcu esp32s to manage the matrix of the switches.

and control some led with a mcp23017 attached.
And send the state of the switches through bluetooth, and receive some values to turn on/off the leds.

This are the specs of my device:

clock 240 MHz
flash 4096 KB
sram 520 KB
EEPROM 448 KB

Because im more familiar with python, i suppose that micropython will do the job here.
----But there is space in this device to put micropython and the code i will need? i mean, module of mcp23017, the bluetooth thing, and the code that reed the state of the switch. Because what i have done was always in raspberry i never found a space problem, and dont get idea of that possible issue. It will be possible?

Also, i see that there is a mcp23017 module for micropython.

-----But, what about the bluetooth thing? (i saw this: micropython-lib/micropython
i can connect to a android phone with that?

Thanks!

Use the high-level aioble package for Bluetooth. https://github.com/micropython/micropython-lib/blob/master/micropython/bluetooth/aioble/README.md
You may need custom Bluetooth code on the phone side.

thanks for the recomendation

4 MB is a lot of FLASH space, can do a lot with that. 512 kB RAM can be limiting sometimes, but not for such a low-data-intensity application as this.

excellent. Then hands to work!
