MQTT over WiFi using nRF7002DK

[umeshdj]

Hello

I am facing issues while pairing nRF7002DK with nRF WiFi provisioner app, when I build the app (provided by nordic and hosted on github). However the pairing is successful when I use pre built hex file kept in \hex folder. I have downloaded the source code from https://github.com/AliNordic/mqtt_over_wifi_nrf7002DK. mqtt_over_wifi_nrf7002DK-master.zip

Hello,

Could you let me know which SDK version you are using to build the application? Additionally, could you provide a brief description of the issue you are facing? Are there any error messages or logs that could give more insight into the problem?

Kind regards,

Hi Abhijith

After manually deleting the already paired BT device from settings on mobile, now it is possible to pair.
