BIPES and Raspberry Pi Pico Ethernet

WizNet is offering a low-cost Raspberry Pi PICO with Ethernet: the W5100S-EVB-Pico at about 9 dollars worldwide. For example, it can be purchased at Digikey here. There are firmwares ready to download and use based on MicroPython and CircuitPython.

If you want to quickly get started, just use this firmware I built:

Next, just use BIPES with your RPI Pico (RP2040) + Ethernet.

Example 1: web client (HTTP GET)

Example result:

=== 
Trying to access http://bipes.net.br
Network connection status: True
HTTP Request result = b'BIPES Test: Live long and prosper!\n\n'
Date and Time from BIPES Server = b'2022-02-13 03:01:18pm'

I removed the Ethernet cable during this program execution, and the try-catch detected it and alerted us (“Error sending data”).
