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


find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(wifi_fundamentals)

target_sources(app PRIVATE src/main.c)

    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?

    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 

    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.

    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?

    Regards,

    Elfving
