I have tested a sketch that works fine on a Photon and am trying to port it over to Bluz.
I used the CLI to compile it and saw that it uses:
text data bss dec hex 17344 116 764 18224 4730
So, since this is within 20K it should be OK.
The only I/O it uses apart fro a serial monitor is SPI, connected in the usual way on A2,3,4,5.
However, when it starts up nothing appears on the serial port. As this is the very first thing that the app does I suspect some kind of loading error.
I have tested the serial cable setup using a modified blink sketch and that works fine.
Any suggestions as to what to try next pls?
