Ahh - so you're trying to send data to the Pico? What are you using to send the data to the Pico?
For graphing, you might find this tutorial helpful - it shows how to store data on an Espruino board, and then serve it up as a graph.
edit: Also, I'm just moving this thread - this forum is generally for people who run Espruino on the ESP8266 itself (not a Pico connected to an ESP8266)....
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
