WPA2-enterprise + PEAP

[kadu]

Can ESP connect to WPA2-enterprise + PEAP networks ? If yes, how to do that ?

There is a longer discussion of this topic on the esp8266 forum http://www.esp8266.com/viewtopic.php?f=6&t=1243&start=15.

WPA2-enterprise is supported in SDK 1.5, so linking this to #1102.

[joostd]

I suspect only eap-tls is supported.

See http://bbs.espressif.com/download/file.php?id=988. The only reference to wpa2-enterprise is in
wifi_station_set_cert_key

Also:

HI guys. Finally WPA2 Enterprise is supported. But I cannot find any example. Actually I saw that only 1 person got it working.
My question is: I need to fill in a username (identity) and a password for the WPA2 and no private key or something like that. Where to fill in the "username" ? Or is this not supported yet. I know this is not an arduino question. But anyway here are the specialists :)

[igrr]

I have not yet added -lwpa2 to linker flag because I wasn't able to get WPA2-Enterprise to work.
If anyone wants to try, feel free to add this flag here

[pauldekkers]

@igrr shouldn't that be line 33? Either way that doesn't work for me, I included

#include <user_interface.h>
...
wifi_station_clear_cert_key();

... in my code to see if that would build, but it doesn't:

sketch_dec20a.ino:5: undefined reference to `wifi_station_clear_cert_key()'
collect2: error: ld returned 1 exit status

But I'm not sure this is the right way to call those functions.

[igrr]

You need to wrap that include with extern "C":

extern "C" {
#include "user_interface.h"
}

Regarding line number: after I wrote that comment a few lines got added, so now compiler.c.elf.libs is on line 33.

[pauldekkers]

@igrr extern "C" does get me further, except for this:

/Applications/Arduino.app/Contents/Java/hardware/esp8266com/esp8266/tools/sdk/lib/libcrypto.a(aes-internal-dec.o):(.irom0.text+0x4): undefined reference to Td0'
/Applications/Arduino.app/Contents/Java/hardware/esp8266com/esp8266/tools/sdk/lib/libcrypto.a(aes-internal-dec.o): In function aes_decrypt_init': (.irom0.text+0x134): undefined reference to Td4s'
collect2: error: ld returned 1 exit status`

I hope you know what's missing :-)

[JeroenBeemster]

I also added the -lwpa2 parameter.
I have exact the same error as Paul.
Same result when I tried this new function: wifi_station_clear_cert_key();

[igrr]

Should be fixed by 70cf3c3

[JeroenBeemster]

Yes, now it compiles. Thanks Igrr, Back to my first question. Where to put the username (Identity)?
How does it work? I am missing one part of the puzzle. And I do not know which

[pauldekkers]

@igrr Great, that compiles and I've actually got it to authenticate. But: with the wrong User-Name, that seems to be set to "tianhao" and not taken from the certificate CN. Maybe it uses the Microsoft UPN attribute or a subjectAltName; I'll try to experiment with that, but suggestions are welcome.
