Nina image send timing issue about aideck-gap8-examples HOT 8 CLOSED

It seems like if a debug message is put on this line , it suddenly works.... but this is not very stable.

Wonder if this has anything to do with the latest improvements on #40 ... The original demo code didn't seem to have any problems with this. On the other hand, this is maybe unveiling timing issues that weren't apparent at first.

hmmm the force viewer doesn't seem to completely solve it.. moving on to the next solution!

so... the current fix is super dirty... but it works for now! Adding a delay just before it start sending imgs through wifi seems to do the trick.

I would still wait for a few seconds before starting up the viewer.py script and all the LED's seem 'stable'

Seems there are still reported problems with it's stability. Sometimes it works and sometimes t doesnt

It seems that the curlpit is this function: https://github.com/bitcraze/AIdeck_examples/blob/b2fcdf05db23d0d2b853b7bed85ce485bef24a01/NINA/firmware/main/spi.c#L129

It seems to keep getting stuck here at spi_slave_transmit(). Unfortunately this is part of the esp sdk...

So it is perhaps on the gap8 side of things, and it seems that the face detector streamer is more stable. This is enabled in the makefile with:

APP_CFLAGS += -DUSE_CAMERA
APP_CFLAGS += -DUSE_STREAMER

With the new AIdeck changes, this will no longer be valid.
