I have a Gravity Analog Electrical Conductivity Sensor ESEN292 V2.0.
To enter the calibration mode you need to enter "enterec" in the serial cmd window.
On my older laptop, this works no problem. I enter "enterec" and I am able to calibrate the sensor.
However, on my new laptop, I can not get the serial monitor to recognize the command.
The code, .h and .cpp files are exactly the same on both computers.
I have even copied the code files from my New laptop to my old one to ensure the cmd still operated correctly. "it did"
I then downgraded my new computer IDE software from 8.12 to 8.11 to match my old computer but the cmd still is not recognized.
Is there something I am missing? maybe a setting or COM issue? IDk....
Direction would be greatly appreciated.
