SK-TDA4VM: wifi station connection issue

Hi James,

Could you try changing the authentication method on the router? Which authentication method are you currently using?

Thank you,

Fabiana Jaimes

Hi Fabiana,

I use the mobile hotspot and the EVM just connect the ap in 3 seconds.

After the disconnection, it will connect and then disconnect periodically.

Is it normal?

Hi James,

This is not the expected behavior. Could you try to use a different hotspot or router to see if its the hotspot you are currently using that is causing the issue?

Thank you,

Fabiana Jaimes

Hi Fabiana,

I try to use another hotspot and it still disconnect.

Therefore, I check the network interface and I don't find any interface about the wireless connection.

It just show the docker eth0 and lo interface.

Is there any other setting to modify?

BR

Hi James,

Does your WiFi card have an antenna? A missing antenna may be the cause for your disconnection since WiFi cards have poor connection on their own.

Thanks,

Hi Fabiana,

Do you mean an antenna on the TDA4VM EVM?

How to set the antenna on the EVM?

Hi James,

Not on the SK-TDA4VM but rather the antenna on the WiFi card. Please refer to the overview information here:

Thank you,

Hi Fabiana,

I have tried to connect wifi router with other kind of EVM and it can work smoothly.

Is there any setting that we miss in sta mode?

BR

James

Hi James,

There isn't any other setting that is not mentioned on the SDK. What is your output when you try the iw wlp1s0 link command?

Thanks,

Fabiana Jaimes

Hi Fabiana,

I cannot find any wireless interface wtih the command ifconfig.

Is it the bug about wireless connection for tda4vm?

BR

James

Hi James,

Try iwconfig instead of ifconfig.

Thanks,

Fabiana Jaimes

Hi Fabiana,

There is no any information about wifi interface

Hi James,

Are you using the Intel-9260 wifi card mentioned on the SDK?

Thanks,

Fabiana Jaimes

Hi Fabiana,

I use the released default image.

Can you specify the details?

Hi James,

Apologies for the late response. Do you still face this issue? You cannot use the board as a WiFi station without a WiFi card. Details on where to order are outlined in the overview section of the SDK: software-dl.ti.com/.../wifi_oob_demo.html

Thank you,
