Bluetooth Serial.readBytes Error

[iroomoon]

Hi! I'm trying to use Bluetooth with Serial.readBytes, but I got this error.

exit status 1
no matching function for call to 'HardwareSerial::readBytes(int [5], int)'

My code is this

if(Serial.available() > 0) {
    Serial.readBytes(dataList, 5);
    for(byte i = 0; i < 4; i++) {
      Serial.println(dataList[i]);
    }

Please help me solving this error
Thank you.

try to define you dataList array as

byte dataList[5];

not int

side note 1: you check if 1 byte is available and then try to read 5. you might get caught by timeout.

side note2: Don't post snippets (Snippets R Us!)

The error means the compiler can not find a version of the readBytes function that matches the types of the parameters you give.

Oh, I changed int to byte, and it really works! Thanks, and it was the first time using the forum so sorry for the snippets .
