I have hexadecimal data that I am receiving using Bluetooth. I want to convert this hexadecimal 2 byte data into a numerical value so I can plot it in a waveform as the data I am receiving is an analog voltage from a sensor.
The data format is like this: 020F so the numerical (decimal) value I need would be 527. I can them manipulate this and convert it to a useful voltage value.
Help please, I tried converting it to a string first and then using the "Hexadecimal string to number" function but it didn't work.
