BLEUUID::BLEUUID
Description
Create a BLEUUID object from a UUID character string.
Syntax
BLEUUID(void);
BLEUUID(const char* str);
BLEUUID(uint8_t* data, uint8_t length);
Parameters
str: UUID as character string used to create object
data: pointer to byte array containing the desired UUID
length: number of bytes in array containing the desired UUID. Valid values of 2, 4 or 16.
Returns
NA
Example Code
NA
Notes and Warnings
“BLEUUID.h” must be included to use the class function.
BLEUUID::str
Description
Get the character string representation of UUID.
Syntax
const char* str(void);
Parameters
NA
Returns
This function returns a pointer to the UUID represented as a character string.
Example Code
NA
Notes and Warnings
“BLEUUID.h” must be included to use the class function.
BLEUUID::data
Description
Get the binary representation of UUID, with the UUID MSB in array index [0].
Syntax
const uint8_t* data(void);
Parameters
NA
Returns
This function returns a pointer to an unsigned 8-bit integer array containing the UUID expressed in binary form.
Example Code
NA
Notes and Warnings
Returned pointer is of const uint8_t* type and will not allow changing of the data. “BLEUUID.h” must be included to use the class function.
BLEUUID::dataNative
Description
Get the binary representation of UUID, with the UUID LSB in array index [0].
Syntax
const uint8_t* dataNative(void);
Parameters
NA
Returns
This function returns a pointer to an unsigned 8-bit integer array containing the UUID expressed in binary form.
Example Code
NA
Notes and Warnings
Returned pointer is of const uint8_t* type and will not allow changing of the data. “BLEUUID.h” must be included to use the class function.
BLEUUID::length
Description
Get the length of UUID.
Syntax
uint8_t length(void);
Parameters
NA
Returns
This function returns the length of the UUID, in units of bytes.
Example Code
NA
Notes and Warnings
A 4-character UUID will be 16 bits / 2 bytes long.
A 8-character UUID will be 32 bits / 4 bytes long.
A 32-character UUID will be 128 bits / 16 bytes long.
“BLEUUID.h” must be included to use the class function.
