nrf7002ek and nrf52840Dk

[Muhammad Usman]

Hi All!

I am trying to connect with static SSID & password to connect with the wififund_less2_exer2_solution . 

Ncs 2.5.2 and vscode studio , Dk's are nrf52840Dk with nrf7002EK

I also tried wifi_provisioning example as well as used the andriod app to provision using BLE .

Both have the same response!

I entered the correct SSID and password.

Uart terminal output with error code is -134

and

cmakelist.txt

cmake_minimum_required(VERSION 3.20.0)


set(SHIELD nrf7002ek)   #added

So in other words this is a completely default version of the solution project, just with the credentials added?

Are you seeing the same issue on the nRF7002DK, if you have it?

thank you for the response!

yes , right credentials added in default with the folliowing line added in the cmakelist.txt as well "set(SHIELD nrf7002ek)

Sorry I don't have nrf7002dk , only have nrf52840dk and nrf7002ek.

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 

# STEP 12.3 Enable support for shell commands

CONFIG_SHELL=n

CONFIG_WIFI_CREDENTIALS_SHELL=n

#CONFIG_SHELL_STACK_SIZE=4096

# Logging

CONFIG_LOG=n

Code compiled successfully with ncs2.6.0 but stuck at the first message .

Thanks & Regards,

Hi Elfving

What I find is that the scan is not started. Although 

CONFIG_WPA_SUPP=y

can you please help me in this regard,

Thanks & Regards,

[Muhammad Usman]

Hi Elfving 

When I tried the Wifi-Station example, it worked for me!

Can you please help me to find out the issue in the Nordic Academy example code I want to use other examples in my project. They are easy to understand and use.

That should work.

To compile with ncs 2.6.0 I disabled the following 

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

Hi Elfving!

Thank you for the response!

Elfving said:

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,

Hello again

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

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?

test.hex
