type of values

[GIOVAZ]

Hi,
I'm working on a Redis Instance, my values are of the kind:

"@K\x80\r\x0e\x80ht"



what kind of data are they? Hexadecimal? Byte Array?

Thanks.

Hello Giovaz,

The values are binary strings and should be treated as byte arrays. The '\xnn' format denotes the character's code in hexadecimal decimal format. E.g.:

127.0.0.1:6379> ECHO "\x72\x65\x64\x69\x73"

"redis"

Cheers

thanks!

How can I write a byte array to Redis?

I am doing a program for arduino, I can write int, double and so on, but
I can't write a  byte array. Must I convert it to in hexadecimal decimal format?

That depends on the language you're using and the client (if any) - it would be best if you could provide a small snippet of what you have. A byte array is one byte (perhaps you have chars?) after another. The hex notation is strictly Redis' - your code should just pass a "string", made of whatever bytes you want.
