Dear everyone,
I'm currently working with the nRF7002DK and attempted to build and flash the following project from GitHub:
MQTT over WiFi nrf7002DK
However, when building the project using nRF Connect SDK v3.0.1, I encountered several warnings related to undefined configuration symbols:
mqtt_over_wifi_nrf7002DK/prj.conf:7: warning: attempt to assign the value 'y' to the undefined symbol WIFI_NRF700X
mqtt_over_wifi_nrf7002DK/prj.conf:10: warning: attempt to assign the value 'y' to the undefined symbol WPA_SUPP
mqtt_over_wifi_nrf7002DK/prj.conf:20: warning: attempt to assign the value 'y' to the undefined symbol NET_SOCKETS_POSIX_NAMES
mqtt_over_wifi_nrf7002DK/prj.conf:80: warning: attempt to assign the value 'y' to the undefined symbol BT_DEBUG_LOG
I’ve noticed similar issues before when using older example code that references Kconfig symbols which have been deprecated, renamed, or moved in newer SDK releases.
Could you please clarify:
-
Why these symbols are undefined in SDK 3.0.1?
-
What are the appropriate replacements or updated configurations in the latest SDK version?
My goal is to implement a minimal MQTT example to send sensor data via Wi-Fi using the nRF7002DK.
If there's an official or recommended sample project that provides this functionality, I would greatly appreciate a link or suggestion.
Alternatively, a brief overview of which configuration options (prj.conf, overlay, etc.) and components are essential for setting up such a "bare-metal" MQTT-over-Wi-Fi application would also be very helpful.
Any guidance or help is much appreciated.
Thank you in advance!
Best regards.
