Detailed Description

A class for Bluetooth communication, inheriting from AComm.

Method Documentation

close

- (void) close

Closes the connection to the Bluetooth device.

Reimplemented from AComm.

initWithDeviceAddress:

- (instancetype) initWithDeviceAddress:

(NSString *)

deviceAddress

Initializes a new instance with the given device address.

Parameters

deviceAddress

The Bluetooth address of the device.

Returns

An initialized instance of BtComm, or nil if the object could not be created.

open

- (void) open

Opens the connection to the Bluetooth device.

Reimplemented from AComm.

read

- (NSData *) read

Reads data from the Bluetooth device.

Returns

The data read from the device.

Reimplemented from AComm.

write:

- (void) write:

(NSData *)

text

Writes data to the Bluetooth device.

Parameters

text	The data to write to the device.

Reimplemented from AComm.

writeAndWaitForResponse:responseStartTimeOut:responseEndTimeOut:completionToken:

- (NSData *) writeAndWaitForResponse:		(NSData *)	text
responseStartTimeOut:		(NSTimeInterval)	responseStartTimeOut
responseEndTimeOut:		(NSTimeInterval)	responseEndTimeOut
completionToken:		(NSString *)	completionToken

Writes data to the Bluetooth device and waits for a response.

Parameters

text	The data to write to the device.
responseStartTimeOut	The timeout interval for the start of the response.
responseEndTimeOut	The timeout interval for the end of the response.
completionToken	A token indicating the completion of the response.

Returns

The data received in response from the device.

Reimplemented from AComm.

writeAndWaitForResponseJson:responseStartTimeOut:responseEndTimeOut:completionToken:

- (NSData *) writeAndWaitForResponseJson:		(NSData *)	text
responseStartTimeOut:		(NSTimeInterval)	responseStartTimeOut
