Wireless Througput Tests with netio
Posted: Sat Oct 04, 2014 8:55 pmHey there,
in some threads it was asked how fast the chip would transfer data over wifi.
Just today I found a hint in some sources, that espressif might actually have been generously enough to include "netio" in their lwip library.
This means, that you can run a pretty much standard performance test on the module, without actually having to compile anything yourself.
The modules runs a netio TCP-only server on port 18767, i.e. you can connect to it like this:
Here's some data I got, while the module was lying about 20cm from my Laptop and connected in sta+softAP mode (i.e. running it's own network while being connected to an ap).
First set is through the 3rd-party ap connection (i.e. laptop <-> ap <-> esp):
2nd set through the softAP connection (i.e. laptop <-> esp):
Note: While I ran the tests multiple times, some values (mostly Tx of the Module) vary between 1 and 25 KBytes/s in between 2 runs.
This means that these are not "guaranteed" values, but instead they should provide you with a rough overview of what the module is capable of (and what it's not.).
Go ahead, run the tests yourself, tell us if your speeds are in the same range, please

EDIT: There's one thing I forgot, sorry for the confusion! You need to call
