Hi Saiff

Thank you much again for your time and concern, I followed your instructions, and when I set

CONFIG_HEAP_MEM_POOL_SIZE=129023

in Cmakelist.txt set(SHIELD nrf7002ek)

This time error message is different, Multiple OK and err=-22

it makes no difference in the output, whether I add .conf file or not as mentioned in the below image.

Is it possible for you to share your project with me without building conf ?

or Further Help regarding that

Again Thanks & Regards,

Muhammad Usman

Hi Muhammad,

wififund_less2_exer2_solution is working perfectly fine at my end, in steps 12.2 and 12.3 try doing what i told you in my first reply, and set

CONFIG_HEAP_MEM_POOL_SIZE=129023 (in the memory section, in your prj.conf file, change it from the original value 153600 to 129023) .

that way it should be working good.

Regards,

Saif

Hi Saiff!

Thank you so much for your time and support!

Sorry, I am unable to connect (wififund_less2_exer3_solution )with the AP when trying to connect via Android app.

For simplicity, I tried wififund_less2_exer2_solution to bypass the android app

but still, the output is the same i tested with static CREDENTIALS as well as via command shell but same error -134

Is it possible for you to test wififund_less2_exer2_solution at your end?

Yes, I am using nrf52840dk + nrf7002ek

Thanks & Regards,

Muhammad Usman

Hi muhammad,

i haven't tried that exemple yet, but if you're working on an nrf52840dk and faced this same error, create a folder named "boards", create a file and name it "nrf52840dk_nrf52840.conf". in this file copy and paste this:

CONFIG_WIFI_CREDENTIALS_BACKEND_SETTINGS=y
CONFIG_FLASH=y
CONFIG_FLASH_PAGE_LAYOUT=y
CONFIG_FLASH_MAP=y
CONFIG_NVS=y
CONFIG_SETTINGS=y
CONFIG_SETTINGS_NVS=y

then don't forget to add it as a kconfig fragment in the build page like this:

Let me know if this sloves your problem,
