Build issues are solved when I got the correct zip files. Now I am testing the RF tool with two som modules, one is transmitter and another is receiver.

I haven’t been able to receive correct packet’s send by the transmitters with tests described in:

5.2 WLAN RF Test Examples

All commands seems to work since I got the correct response from driver.

So some progress but we are not ready for the type approvals since the TX RX pair in not working properly..

This receiver transmitter test is also working now , reason for bad behavior was wrong antenna path setting, so now this case can be closed

Hi @Lassi !

Thanks for the feedback!

Could you please mark as solution the most suitable message in this thread? This part is pretty important :slight_smile:

Best regards,

Hi

The solution came from email but I marked a one message which was related to this solution..

Hi, we did some pre-measurement’s in type approval laboratory and everything seemed to work.

One question was asked from the SGS type approval team. This is more related to EMC testing but is it possible to control the wifi with normal toradex image ( normal operation with normal wifi driver )like this:

  1. force the wifif to use 5GHz band only
  2. Control the output power

If this is possible what control interface is used and is there a manual for the command syntax.

Best regards

Hi @Lassi !

In order to enable/disable the wireless bands and control the output power of the Wi-Fi (and more test-related capabilities), the image must be built with manufacturing mode enabled.

Currently, Toradex doesn’t release images with this enabled.

Thank you Henrique for the quick answer. I was kind of expecting this kind of answer. I’ll forward this information to type approval lab…

Hi @Lassi !

Do you have any updates regarding this topic?

Do you need further help?

Best regards,

Hi Henrique

One issue came during the EMC tests in 2.4GHz band. Wifi is set to communicate via 2.4GHz band and the bluetooth is communicating also in same band. Is there any restrictions using the same 2.4GHz band in wifi and in bluetooth communication. Is ti possible to communicate same time using same band.

This can be a wrong setup in wifi settings also but the communication in certain EMCtest fails at the moment. I am going to make a visit to type approval laboratory today just to check are the settings correct. It would e great to get the information about the wifi/bluetooth chipset support the wifi/bluetooth communication in 2.4 GHz band same time. I checked the datasheet and I could not find any comment’s about using same band..

Hi @Lassi !

Thanks for the update.

Can you please elaborate on which kind of issue happened? The more details, the better :slight_smile: (also to avoid misinterpretations)

I will ask internally if there is some information about it.

Best regards,

32

They decided to test wifi only, without bluetooth… But the information about simultaneous use of wifi and bluetooth on same band would be very interesting…

33

Hi @Lassi !

I see.

But please share as much information as possible about which issue happened during the tests.

Best regards,

34

Ok, I’ll ask for more details about the failure…
