Hello Nagendra,

[quote user="nak"]Thank you for your reply[/quote]

No problem at all, I am happy to help!

[quote user="nak"]so what changes i should do..??[/quote][quote user="Karl Ylvisaker"]What is the maximum length of your characteristic's value?[/quote]

I have not really seen any relevant part of your code - namely your custom service declaration - but if you are following the tutorial you will need to change the maximum length of the characteristic to allow an input bigger than 1 byte.

Hello,

[quote user=""]here i am able to receive only one byte [/quote]

What is the maximum length of your characteristic's value?
The default max length of the characteristic in the tutorial is sizeof(uint8_t), which is 1 byte.

attr_char_value.max_len   = sizeof(uint8_t);

Karl
