Getting WFI Working on TF3xx with ESP Module

[PhilC]

A quick question , is this just for 330 and 360 cards only?

Yes. The CD32 has the UART pins on the edge connector.

EDIT: I could have added this to the A1200 card but people use PCMCIA there. No chance of it on an A500 card would required a full UART chip.

Thanks, that explains it.

Did some nasty soldering and got my TF-330 online. Brilliant stuff.

Has anyone tried baud rates above 115200?

No. ESP Slip router doesnt go above that from the docs.

I can run it at 216000bps but the CPU starts really struggling when you up the speeds. I think that 1mbps shouldn't be an issue with TF360 (If that's the only bottle neck). I think the documentation only tells that it defaults to 115200 since some USB devices max out at that rate but 21600 bps can be achieved just by editing envarc:sana2/slip0.config and setting the bitrate in the esp console. If that fails you can probably try a slower rate, say 201600 that still produces a nice boost.

I'm very surprised the CD32 uart can handle that at all. I wouldn't expect it to get much faster.

Ahh well I benefit from not knowing what I'm doing.

Keep going. Tell me what the limit is.
