ESP8266 looks good.
So MQTT would be a better option? https://www.espruino.com/tinyMQTT
Thanks! -
I am presenting at the fair and I would like to include Pixl.js.
I need bidirectional communication/websocket between pixl and the web app.
I have Android phone with mobile data (wifi, BT, BLE).
I can also use RaspPi 4 using EspruinoHub (BT)? Or ESP32 dev board (serial or BT)?
What would be the easiest option? -
So I got mention Arduino ESP8266 board.
Can I connect it directly/pins to pixl.js without soldering? How? All DIP switches to off (closer to numbers?) and use Debug Port TXD/RXD?
I would like to power both boards using CR2032 battery. How?
How do I verify if ESP8266 has an appropriate firmware?
Any additional info and pictures would be much appreciated.
Thank you.
