speedtest cli with Raspi Pico

[mauriceee31]

Hello,

i want to build a small stupid devices, that logs my internet speed at home. For that I want to try and build it with a Raspberry Pico W. I haven't found any documentation if it's possible to use speediest cli in micropython. I its a dumb question im sorry, because a am a newbie at python and micro python.

Hope someone has an answer. Thanks in advance!

You did not tell exactly which interface you want to test. If it is the internet connection between the provider and your local network, a Pico W is surely not suitable. I just tested the transfer rate of a Pico W to a PC in my LAN, and it was ~1800kByte/s or roughly 20-25 MBit/s. If your internet provider promises higher Rates, the Pico W is the bottleneck. For performance test better use a wired device, like a Raspberry Pi or a PC. And even then, the speed of the components in your LAN may limit the transfer rate.

Yep what Robert said, but also FYI https://github.com/micropython/micropython-lib/tree/master/python-ecosys/iperf3 is a micropython implementation of the iperf3 tool which you can use for speed testing.

@jimmo Do you happen to know, why a iperf3 test may start with ~10 seconds phase of not transmission? That happens with e,g, the mimxrt port, independent of the interface. Example below. Looks like a sync problem.

@robert-hh Nope sorry... I haven't seen this myself. Feels like one of those things that getting to the bottom of might reveal something interesting, but might be non-trivial.
