I'm experiencing an issue with my ESP32 software, written in C++, where it consistently hangs on the first screen. I need a developer to dissect and fix the root cause of this problem. The ESP32 runs a program that allows users to control levels of a gas coming through a tube. I mixes 100% CO2 with room air. When the machine starts up it goes through a calibration process and gives a message saying "Don't put on the Mask". After the calibration process then it allows user to adjust the time/session duration. After editing some code it is getting stuck on the "Don't Put on the Mask" message during calibration and not getting to the next screen. When my other developer compiles the code on his computer it works fine on the same device. How...
