CYW43 error: hdr mismatch

[sam57719]

Pico 2W

With UI Log Enabled, Sensor Log Enabled and a BME280 connected.

Constant errrors in SMIBHID log - appears to be slowing down network requests.

My board doesn't do this. Can you confirm the commit you have copied to the board, your config file contents (sans passwords), the UF2 for micropython used and the pinout of all connections to the pico?

Can you also confirm no continuity between pins on the pico i.e. a solder bridge where there shouldn't be.

This post suggests a firmware issue, but it might be firmware + incorrect wiring or similar: https://forums.pimoroni.com/t/plasma-2350-w-wifi-problems/26810/25

I've retested my setup and confirmed I am running nightly build 365. This is no longer available as a nightly build, so I have pushed to a firmware folder on this related branch so we have a known working version while the nightly builds stabilise to a stable release.

@sam57719 Is this still an issue?

Not tried. Will see tomorrow
