my question is, how can I receive 3 integer values in Arduino, which I send from my android phone. I send all 3 values at the same time and I also need to read them in about the same time. I hope you can help me.
If there are no other constraints, send them as a text with delimiters and a terminating character.
e.g. something like "123;45;678\n"
On the arduino, either manually check for those delimiters and convert the digits to a number on the fly, or use strtok and atoi after reading the whole line.
