Attached is the source to blink the NINA only LEDs for the Vidor and 1010. There’s a #define at the top of the blink.c file:
Comment that out for the 4K.
Also - in the cpu_start.c file - at the bottom - add the task create (pinned) call:
xTaskCreatePinnedToCore(&blink_task, “blink_task”, configMINIMAL_STACK_SIZE, NULL, 5, NULL, 1);
Alternatively, I have a couple of pre-built bin files posted here:
https://forum.arduino.cc/index.php?topic=597999.0 - look at the bottom of that thread.
I’ve tested both with the WifiWebClient sketch - seems to work pretty good - the 4K has some interesting color combinations.
Note: unzip the attached in:
C:\esp\nina-fw\arduino - if this is on your C: drive - as an example.
And, for cpu_start.c - you’ll need to add the above here:
Once that’s done - your subsequent builds will blink the LEDs (NINA Only LEDs).
