MicroPython has this great feature: WebREPL. It uses WebSockets to allow interactive Python shell sessions to the device running MicroPython, and also allows files to be uploaded and downloaded – all over the network, so we can easily program, debug and interact with ESP32, ESP8266 and other MicroPython enabled boards over Wifi! CircuitPython still does not have WebREPL, but I am looking forward to it (https://github.com/adafruit/circuitpython/issues/4050)!
However, sometimes is hard to discover which IP is assigned to a specific board, especially if the board is connected to a USB power bank or a power supply and has no display/interface to show the IP. Sometimes I use the the Wifi Access Point configuration page to see the DHCP client list and try to guess which one is leased to the board I am working with.
In that way, we decided to add a “WebREPL device scanner” feature on BIPES. You can use this feature to discover/identify all IP addresses associated with WebREPL ports using WebSocket (on port 8266). The feature is presented as a button next to the Connect button and opens a new page. It is useful even if you don’t use BIPES, but need to find the IP address of a board on the same network your computer is.
It is a quick and simple solution, which can save time and make activities more practical. Hope it helps you!
