VOXL flight wifi in soft AP - only 2 connections possible

marian

Hi,

I use voxl flight with the Wi-Fi on soft AP mode, and its allow to connect only 2 devices at it at the same time. Can increase this limit?

Hi @marian,

Please see the following post regarding VOXL1 wifi AP maximum number of clients : https://forum.modalai.com/topic/3523/maximum-connections-to-wi-fi . Hopefully that helps!

@Alex-Kushleyev thanks for your reply.

I follow the topic you provide, but still don't work. I have set up the max_num_sta=32, restart the wifi / reconfigure the wifi , still have only 2 connections permitted.

I didn't find anything else in the configuartion or the scripts which can limit the connections.
Did the hardware have a limitation instead of it?

@marian , I was able to replicate it and when running dmesg, I see the following message:

[  390.539854] R0: [VosMCThread][02:38:25.067557]  wlan: [3231:E :PE ] limProcessAssocReqFrame: 914: Max Sta count reached : 2

Changing max_num_sta in hostapd.conf did not help.

After doing a little bit of digging, it seems like this may be a hardware limitation of the wifi hardware on VOXL1 in SoftAP mode : https://android.googlesource.com/kernel/msm.git/+/android-msm-bullhead-3.10-n-preview-1/drivers/staging/qcacld-2.0/CORE/MAC/src/pe/lim/limProcessAssocReqFrame.c#847 .

It could also be a setting somewhere low level and unfortunately we don't have any information on that. Sorry about that.

The wifi module on VOXL1 is QCA6174.
