As far as I can tell readStringUntil( ) function is not available in SoftwareSerial library
As I say i've tried reading it as a char, byte etc and doing that means I don't use the readStringUntil() function. I've tried read() when declaring as anything but a String and readString() and readStringUntil() when declaring inData as a String. My code is kind of an example, I've tried every way I can think of reading it with no avail.
