Héllo James,
So bad to hear from no source possible !
About binaries, I cannot get the latest published one from NXP.
The support answer me I need a NDA.
The support then refuse my proposal of NDA !
I may understand proprietary license, but as a user, I cannot get
nothing at all !
Regarding the issue, you can see the full details of my tests, and I
just edit to add a brief summary at the first comment of the following
issue:
https://github.com/NXP/mwifiex-firmware/issues/1
Please, look at it.
It is full detailed.
If anything missing, please, ask what you need.
Regards,
Gérald Kerma
