Detailed Description

A model of remote BLE descriptor.

Member Function Documentation

getHandle()

uint16_t NimBLERemoteDescriptor::getHandle

(

)

Retrieve the handle associated with this remote descriptor.

Returns

The handle associated with this remote descriptor.

getRemoteCharacteristic()

NimBLERemoteCharacteristic * NimBLERemoteDescriptor::getRemoteCharacteristic

(

)

Get the characteristic that owns this descriptor.

Returns

The characteristic that owns this descriptor.

getUUID()

NimBLEUUID NimBLERemoteDescriptor::getUUID

(

)

Retrieve the UUID associated this remote descriptor.

Returns

The UUID associated this remote descriptor.

readUInt16()

uint16_t NimBLERemoteDescriptor::readUInt16

(

)

Read an unsigned 16 bit value.

Returns

The unsigned 16 bit value.

Deprecated:

Use readValue<uint16_t>().

readUInt32()

uint32_t NimBLERemoteDescriptor::readUInt32

(

)

Read an unsigned 32 bit value.

Returns

the unsigned 32 bit value.

Deprecated:

Use readValue<uint32_t>().

readUInt8()

uint8_t NimBLERemoteDescriptor::readUInt8

(

)

Read a byte value.

Returns

The value as a byte

Deprecated:

Use readValue<uint8_t>().

readValue() [1/2]

NimBLEAttValue NimBLERemoteDescriptor::readValue

(

)

Read the value of the remote descriptor.

Returns

The value of the remote descriptor.

readValue() [2/2]

template<typename T >

T NimBLERemoteDescriptor::readValue ( bool  skipSizeCheck = false )

inline

Template to convert the remote descriptor data to <type>.

Template Parameters

T	The type to convert the data to.

Parameters

[in]

skipSizeCheck

If true it will skip checking if the data size is less than sizeof(<type>).

Returns

The data converted to <type> or NULL if skipSizeCheck is false and the data is less than sizeof(<type>).

Use: readValue<type>(skipSizeCheck);

toString()

std::string NimBLERemoteDescriptor::toString

(

void

)

Return a string representation of this Remote Descriptor.

Returns

A string representation of this Remote Descriptor.

writeValue() [1/5]

bool NimBLERemoteDescriptor::writeValue	(	const char *	char_s,
		bool	response = false
	)

Write a new value to the remote descriptor from a const char*.

Parameters

[in]	char_s	A character string to write to the remote descriptor.
[in]	response	Whether we require a response from the write.

Returns

false if not connected or otherwise cannot perform write.

writeValue() [2/5]

bool NimBLERemoteDescriptor::writeValue	(	const std::vector< uint8_t > &	vec,
		bool	response = false
	)

Write a new value to a remote descriptor from a std::vector<uint8_t>.

Parameters

[in]	vec	A std::vector<uint8_t> value to write to the remote descriptor.
[in]	response	Whether we require a response from the write.

Returns

false if not connected or otherwise cannot perform write.

writeValue() [3/5]

template<typename T >

bool NimBLERemoteDescriptor::writeValue ( const T &  s, bool  response = false  )

inline

Template to set the remote descriptor value to <type>val.

Parameters

[in]	s	The value to write.
[in]	response	True == request write response.

Only used for non-arrays and types without a c_str() method.

writeValue() [4/5]

template<typename T >

bool NimBLERemoteDescriptor::writeValue ( const T &  s, bool  response = false  )

inline

Template to set the remote descriptor value to <type>val.

Parameters

[in]	s	The value to write.
[in]	response	True == request write response.

Only used if the <type> has a c_str() method.

writeValue() [5/5]

bool NimBLERemoteDescriptor::writeValue	(	const uint8_t *	data,
		size_t	length,
		bool	response = false
	)

Write a new value to a remote descriptor.

Parameters

[in]	data	The data to send to the remote descriptor.
[in]	length	The length of the data to send.
[in]	response	True if we expect a write response.

Returns

false if not connected or otherwise cannot perform write.
