The time has come when I have to choose which Bluetooth and which wifi chip/module to use. After may be a whole days browsing/searching, I seem to come to the following conclusions: Bluetooth is available from more than one source as a single package solution, some of them are documented and really ready to use. I tend to stop at NSCs part, LMX9830 - stocked and inexpensive at Digikey, plus that NSC are among the "good ones" in my book.
Quite a different story with wifi - to an extent I begin to think there is something I don't get, some general standard I have not read or whatever. Nothing - 0 - one can buy and use as a peripheral to make conecting to wifi as much work as say writing a new Ethernet driver plus perhaps ARP or something. Most seem to use a Marvell chip - in another thread all posters agreed it is a waste of time trying to talk to them (I guess they will talk only to party members). So this part is secret. A while ago Guy Macon posted a manual for an NXP part which does contain much more information than anything else, but the part has some ROM with firmware inside it and while the mechanism to talk to the internal CPU is documented, the syntax - command set etc. - is simply not present, so this info is probably secret as well. (Guy, please let me know if you manage to squeeze some more data at some point).
Hopefully there are people around who can prove me wrong so it turns out wifi is not reserved for party members only.
Are all those USB/PCC/SD card etc. wifi adaptors documented for MS and similar only? Sounds incredible. Anyone having been able to talk to such a device directly?
