java - why do we need to convert number value in string value to send it by bluetooth -
i know why need convert number value (int, double...) in string value send or bluetooth example.
in java, use:
byte[] buffer= new byte int bytes string strreceived=new string (buffer,0, bytes)
but possbile value bluetooth type ? :
int received = new integer(...)
edit : want send data bluetooth, problem if need send string data bluetooth, 1 character = 1 bytes , data 10 digits convert in string 10 bytes. if can send/get directly data in double/int format, can win 6 bytes each data (int/double 4 bits).
thanks !
