Hello again

Sorry about the wait, Easter is a public Holiday in Norway.

sorry, I don't have it as we are required to use nrf52840 because of its 8dbm output power.

Understood.

So you get this output immediately with, when flashing the unmodified wifi-provisioning example (besides the modification of adding the nRF7 shield to cmakelists)?

I just tried this myself in NCS 2.5.2, and I am not getting exactly that. Though I am bit uncertain if this might be due to some OTP programming of the nRF7. Could you try flashing this hex I've built, and see if you see the same issue you saw on your side?

Hi Elfving!

Thank you for the response!

[quote userid="103347" url="~/f/nordic-q-a/109214/nrf7002ek-and-nrf52840dk/475434"]Do you have a nRF5340DK you could use?[/quote]

sorry, I don't have it as we are required to use nrf52840 because of its 8dbm output power.

One more observation I tried a wifi-provisioning example with ncs2.5.2/2.5.0/2.4.0 and nrf52840dk+nrf7002ek.

However, this sample supports the DK I have. But I got the following serial output.

and android app

The only change I made is to add

set(SHIELD nrf7002ek) // in cmakelists.txt of the original sample

Can you please help me where is the issue?

when I compared this sample with the nanopb sample, I was unable to find out the

#include <pb_encode.h>

#include <pb_decode.h>

decode_message()

and

encode_message

functions in the wifi-provisioning example.is it related to nanopb configuration and cmakelists.txt files?

Can you please help me with how to configure that if this is the issue?

Thanks & Regards,

Muhammad Usman

That should work.

One more observation is that , when i used ncs2.6.0 then i got following error related to ram overflow

phyr-eabi/bin/ld.bfd.exe: region `RAM' overflowed by 35564 bytes.

To compile with ncs 2.6.0 I disabled the following

[/quote]

I would assume it should work with multiple versions of NCS, 2.6.0 as well, though the course was tested with 2.5.0, and there might be some additions to the Wi-Fi stack that has made it require a bit more RAM in 2.6.0.

I guess this is why it says that this course is only supported on the nRF7002DK, or the nRF5340DK with an nRF7EK. It needs the additional RAM that the 53 provides.

Though as you've found out, multiple samples work on the nRF52840.

Do you have a nRF5340DK you could use?

Elfving
