Re: Programming ESP8266 on Chromebook in Nov 2019; with both Linux/android apps now accessible, is it easier?

I too have been looking for a solution using a Chromebook using crostini/Linux. Unfortunately it is not possible as of right now as USB support for such serial devices is not present in chrome. Maybe it will change in the future.

For Arduino, there appears to be some sort of web app and ide.

Re: Web-Scraping (with BeautifulSoup4?) on ESP32

Not sure about bs4 but a quick Google search shows that there are available APIs for weather data, for example, openweathermap Haven't used them but using requests module they should return json that should be figurable with the micropython json module.

Re: STM32F103C8T6 Data Acquisition board

Many thank for the response. I suspected as much that this was the limitation. I like the compact size and all in one solution if that board. Will see if I can rig up something with a an esp32, a proto board, and some terminal blocks.

For some simple data acquisition, I'm planning to get one of these STM32F103C8T6 boards: https://www.aliexpress.com/item/32965348225.html. Is it possible to get MicroPython to work on these? Thanks.

Re: ESP32 access via Ipad

Indeed, I use webrepl on my esp32. Works just fine. There is no way around setting it up the first time using a direct USB/serial connection.

Edit to add: there is also telnet server for micropython. Not much experience with it.
