Thingy:91 X - WiFi "UDP only"

[Achim Kraus]

In some other tickets it's said, that using the nRF7002 for IP traffic doesn't work, because that requires too many resources on the nRF9151.

Does this apply for a "UDP only Network" (plain UDP without DTLS nor TCP/TLS)" as well?

Has someone tried to setup a "UDP only Network" for the Thingy:91X + WiFi?

Hi, 

I would suggest using the Thingy:91X Cellular connectivity for UDP such as this UDP or Cellular: UDP samples. The reason is the same as my colleague's explanation in this post.

:-). I do so.

I was mainly asking, if the TCP buffers are disabled (I guess, that's the most part of the mentioned 200K RAM), what will then be required. But I start to remember, that the second question will be more, that for cellular the ip-stack is "offloaded" to the modem, while for wifi it uses the ip-stack of zephyr. I guess that would also cause issues, if zephyr doesn't support both modes simultaneously.
