Can't network 2 5100s modules together

nathanmayall commented 2 years ago

Hi there,

For an experiment I'm trying to network 2 pico devices with the Wiznet 5100s ethernet hat.

I've used the same code on both, and I'm hoping to perform an operation where they have a html page and perform get requests to each other,

At the moment I'm configuring them to both be servers, then at a set interval they can just send a request to the other, but I can't get that far.

This issue I'm having is below, here's the debug. I'm assuming anything can be wrong, There's not much documentation out there that I can find on how to directly connect these 2 devices.

It's worth noting that on the other device the IP is 192.168.2.1, which is what I've set the gateway to.

code.py output:

Can anyone point me in the right direction? I don't know where to go from here.

Thanks

You may want to bring this to Discord and ask in #help-with-circuitpython. Are both devices running when this exception occurs? What version of CircuitPython is installed? Do these devices connect to each other through a switch or router?

@anecdata I fixed the byteorder by applying the fix in #64. Still got an error where an empty text response is received by the client though. I'll jump in discord now.
