PRESTO Error messages [CYW43]?

Support

My Presto has just provided a couple of error messages I do not understand. It kept going but as the software is still in Beta I thought someone might be interested.

The program pulls down data from an earthquake website and plots their position on a world map held as a jpg. I’m pulling down 400 long lines at a time from the website, chopping out the fields and storing them before further processing. The Presto is working quite hard!

This PRESTO is bags of fun!

We had similar CYW43 errors before on a plasma2350w, see Plasma 2350 W wifi problems. It is a very long thread but to the end the problem was solved with a new firmware version.

I’ve been working and running this project on an off for ages incrementally increasing the scope by increasing the amount of data downloaded and carrying more analysis. This was the first and only time I’ve seen it but thought as PRESTO is still beta I’d better report it.

I’m getting interesting results now we have multiple quakes in Greece from Santorini.
