Posted: Tue Apr 04, 2006 11:36 am    Post subject: WLAN function in Open-R SDK

Reference:
Open-R SDK for AIBO ERS-7: file \OPEN_R_SDK\OPEN_R\include\WLANDriverMsg.h
documentation: file \OPEN_R_SDK-docE-1.1.5-r1\Level2ReferenceGuide_E.pdf - Chapter6 wireless LAN API, pages 86 & 87
 Code: /*   WLAN statistics */ struct EtherWLANStatistics {   uint8  link;   // in percentages of max value   uint8  signal; // in percentages of max value   uint8  noise;  // in percentages of max value   uint32 invalidIDCount;   uint32 invalidEncCount;   uint32 invalidMiscCount; };
About the noise value, it seems to stay constant once the AIBO is booted, & the value doesn't change till the AIBO is rebooted.
Example: I booted my AIBO on a very noisy (wavely speaking, of course ;) ) environment, & the noise given was high. I brought my AIBO far from this noisy environment, the value given was still constant. I rebooted it, the new value was low. I brought it back to the noisy environment, the value was still low, till I rebooted, & the value became high again.
Used: URBI & URBIlab, #graph wlan.noise that refers to this noise.
It seems to be a bug from Open-R (even if the latest version, OPEN-R SDK 1.1.5 r5, has corrected some stuff from the WLAN drivers since version r4), can anyone confirm? :)
You could use the ERA201D1Info sample program (\OPEN_R_SDK-sample-1.1.5-r2\sample\common\ERA201D1Info\) you can download here.
I tried to do it myself, but my WinXP - Cygwin environment doesn't work enough to compile the program. :-S

My advise is to search Tekkostu's code. AFAIR, they have wireless statistics.

Unfortunately, I don't really have the time to install it to compare with my URBI results. & I didn't manage to make Open-R run on my AIBO, otherwise I would have run the ERA201D1Info sample program myself. If anyone could run it for me, it would be cool. ;-) -- Le Sage W/BO Project (Wi-Fi over AIBO)Last edited by TCD on Thu May 04, 2006 12:35 pm; edited 1 time in total

 Posted: Wed May 10, 2006 11:34 am    Post subject: That's nice, but unfortunatly I don't have an AIBO to work on anymore; mine went back to my university :'-( . So I can't do the test. But I'm still interested in the ERA201D1Info sample program (Open-R) & the Tekkotsu results on an ERS-7 Mind 2. ;-) ADD: I'm lost. You are talking about Mind 3. Doesn't Tekkotsu load on a programming memory stick, where there is an Open-R base & the Tekkotsu added on it, and no trace of AIBO Mind? Isn't usually AIBO Mind on a seperate memory stick? In this case, Mind shoudn't have any effect on this, only the Open-R version used. That's the case for URBI: you are highly recommended to use a seperate memory stick for programming, as URBI is based on the Open-R SDK only, and not Mind. By the way, the latest version (Open-R v1.1.5-r5) includes some WLAN Driver adjustment added to the r4 version (cf http://openr.aibo.com/openr/en/viewtopic.php?t=252 → \OPEN_R_SDK-1.1.5-r5\OPEN_R_SDK\CHANGES_E.txt ). -- Le Sage W/BO Project (Wi-Fi over AIBO)

Correct, to use the precompiled memory stick I link to above, you need to copy the files onto a "programming" memory stick, not an "AiboMind" stick. We include everything you need in the archive (hence why I call it a memory stick "image"), so you should be able to unzip onto a blank stick and be good to go. (If you still had an Aibo to test on anyway :^\ )

In fact I was saying all of this, beacuse you said:

So here it would be more like ERS-7 (not Mind 3, since you didn't use the Mind 3 memory card).
When you said earlier model, you meant something like an ERS-2x0?
PS: no, no AIBO to test on now. :-S

 Posted: Tue May 16, 2006 2:14 pm    Post subject: There's been a few revisions to the ERS-7 hardware, each corresponding to a version of the AiboMind software -- not all ERS-7's are identical. As far as I know, the biggest difference between revisions is that I *believe* the M3 revision (corresponding to the AiboMind 3 software) includes 802.11g wireless (as opposed to 802.11b in previous revisions).

Unfortunately, I don't have the means to look further on this anymore. Thanks anyway for your precious and continuous help. :-) -- Le Sage W/BO Project (Wi-Fi over AIBO)

This is independent of the AiboMind3 software (the AiboMind3 software will run on older ERS7 hardware too) As mentioned the OpenR SDK (and more recently the RCODE SDK) have been updated to work with the new hardware.
