Hi,
In a previous post, I got help getting my rather complicated Blynk-based sketch, which had been running just fine, to load sketches and mostly run once again.
The current issue I have narrowed down to invocation of Blynk.begin(). I can write messages to the serial output just fine up until that call. After that, nothing. I've attached a simple sketch that is the minimal to demonstrate the issue.
HOWEVER, strangely, I am able to connect to the board through the iPhone Blynk app, and in the attached program, I see evidence of liveness in response to a slider widget. But, none of the prints ever show up in the serial monitor after Blynk.begin(). This leads me to believe that something in that call messes up the serial port. But what? And how to fix?
Expected output from attached sketch:
Successfully ran setup
Trying to connect to cloud server
After running Blynk.begin()
Blynk.run() first time
After Blynk.run() first time
Value from app: 3
Value from app: 4
Value from app: 5
(etc...)
What I get is only the first two lines, ever. Note that I actually moved the Blynk.begin() out of the setup() and as a one-time call under loop(), just to see if anything different would happen. It doesn't.
Thanks for any advice,
Charles
