Hi,
how can I convert a byte array to Sting?
Either I am to stupid to search nobody required it so far. Most likely the first option
Thanks
Robert

But you definitely don't want to use the String class. Search the forum for it and you'll find enough reasons not to use it.
String myString = String(myByteArray);
how can I convert a byte array to Sting?
I don't believe I've ever heard of a Sting class. Are you raising bees? Or scorpions?

Neither - he's an FBI agent looking to entrap a rival CIA agent

Hi,
thanks for the answer. That's what I tried first. It works fine with a char array but not with an array of bytes.
Maybe my mistake is somewhere else.
Here my examples:
fails with "call of overloaded 'String(byte [5])' is ambiguous" :
void setup(void){}
void loop(void)
{
byte byteArray[5];
strcpy((char *)byteArray,"0123");
String myString = String(byteArray);
}
compiles fine:
void setup(void){}
void loop(void)
{
char byteArray[5];
strcpy((char *)byteArray,"0123");
String myString = String(byteArray);
}
Thanks
Robert
Ah, byte is a typedef for "unsigned char" - there is no unsigned char prototype for the String constructor.
Cast it to (char *) and it should be fine.
void setup(void)
{
}
void loop(void)
{
byte byteArray[5];
strcpy((char *)byteArray,"0123");
String myString = String((char *)byteArray);
}

Perfect!
Thanks for the great help.

hi all,
this worked for me
String myString = String((char*)myByteArray);
this worked for me
That calls two constructors, the equal operator, and the destructor.
String myString = (char*)myByteArray;
Does the same thing with only one call to the constructor.
Hi, im not making an answer, but i have a problem, i dont't really know what to do.
im trying to use this:
String myString = String(myByteArray);
but doesn't work and returns me this:
no matching function for call to 'String(void (&)(byte*, byte))'
i'm trying to do it with Byte Buffer, because i need to convert to String theme i would send to dataBase.
i would appreciate so much if someone helps me
