Applications compile and (looks to) load but never runs

I see the string of unprintable characters in the serial monitor but no output from the program.

As a genreal info, you must match the monitor speed configuration of PlatformIO (which is passed to the miniterm.py serial monitor program) to what you are doing in your firmware. So if you do

@averageguy

Serial.begin(115200);

the must be a

monitor_speed = 115200

(docs) in the platformio.ini. Otherwise the default baud of 9600 applies.

Also, try to avoid

@averageguy

lib_extra_dirs = ~/Documents/Arduino/libraries

in favor of explicit dependency declarataions. In this case your firmware doesn’t even depend on any other library, so it’s safer to leave it out, lest some unrelated library is somehow included and overlooked.

@averageguy

When I start the serial monitor and press the reset button on the chip, I get the garbage string followed by a “HTTP server started” message which tells me that the program that is running is what was there before

Looks to me like you may have uploaded the wrong project by not selecting your active project correctly. Same issue as in After update PlatformIO it looks like it does not read platformio.ini - #7 by maxgerhardt?
