NXP 88MW300 cannot connect to Raspberry Pi 4 Model B set to access point mode (WPA2 only)

[ratoc]

I am unable to connect from my NXP 88MW300 to my Raspberry Pi 4 Model B.

The problem occurs when the Wi-Fi module has firmware p144.
mw30x_uapsta_148836p135.bin ... good
mw30x_uapsta_148836p144.bin ... not good

No problem with WPA.
Only when set to WPA2, for some reason it fails with 802.11 association.

No problem with Buffalo routers, etc.
Only WPA2 on Raspberry Pi 4 Model B has the problem.

Do you have any information?

Hi,

I am sorry for my late reply.

Do you have any logs or screenshots you can share with us? It might help us to understand the reason of your problem.

Best regards, Daniel.

Thanks for your reply.
Sorry, I have no way to monitor the contents of 802.11.

\wmsdka_bundle-V6.0.r7.p2\sdk\src\wlan\wifidriver\mlan_glue.c
The following error log is displayed in the function wifi_process_cmd_response() in the above c source code.

"Assoc failed: Status: 38".
Status 38 is INVALID_PARAMETERS.

\wmsdka_bundle-V6.0.r7.p2\sdk\src\wlan\wifidriver\mlan_join.c
Is the parameter created by the function wlan_cmd_802_11_associate() in the above c source code bad?

However, if you rewrite the binary of the Wi-Fi module of the 88MW300 from p144 to p135, it will no longer be Status 38.

Thank you for the feedback.

I see you are using the WMSDKA. By any chance, have you tried the MCUXpresso SDK examples, and if that is not the case, could you please try them and tell me if the problem still occurs?

Hi,

Thanks for the information.

I'll consider using the MCUXpresso SDK.
