Types

type FlowControlOff 

type FlowControlOff struct {
	CommandResponse uint8
}

FlowControlOff The flow control command is used to handle the aggregate flow. When either entity is not able to receive information it transmits the FCoff command. The opposite entity is not allowed to transmit frames except on the control channel (DLC=0). [ETSI TS 101 369 V7.1.0, 5.4.6.3.6 ]

type FlowControlOn 

type FlowControlOn struct {

}

ModemStatus It is desired to convey virtual V.24 control signals to a data stream, this is done by sending the MSC command. The MSC command has one mandatory control signal byte and an optional break signal byte. This command is only relevant when the basic option is chosen. [ETSI TS 101 369 V7.1.0, 5.4.6.3.7 ]

	CommandResponse uint8

	// DLCI Data link connection for which parameters are being negotiated
	ServerChannel uint8

	// FrameTypes The type of frames used to carry information on the channel
	// UIH frames indicated by the value 0x1000
	FrameType uint8

	// ConvergenceLayer RFCOMM uses Type 1 (unstructured octet stream) 0x0000
	// in versions after 1.0b this may also be set to 0x0F to enable credit
	// based flow control
	ConvergenceLayer uint8

	// CreditBasedFlowControl overwrites values for ConvergenceLayer and FrameType
	CreditBasedFlowControl bool

	// Priority Assign a priority to the data link connection: 0 (lowest) - 63 (highest)
	Priority uint8

	// Timer In RFCOMM is the timer elapses, the connection is closed down. The
	// timers value is not negotiable but is fixed at 60s. This field is set to
	// 0 to indicate that the timer is not negotiable
	Timer uint8

	// MaxSize The maximum size of the frame
	MaxSize uint16

	// MaxRetransmissions The maximum number of retransmissions. Because the
	// Bluetooth baseband gives RFCOMM a reliable transport layer, RFCOMM will
	// not retransmit, so this value is set to zero
	MaxRetransmissions uint8

	// WindowSize The window size for error recovery mode. RFCOMM uses basic
	// mode, so these bits are not interpreted by RFCOMM
	WindowSize uint8
}

ParameterNegotiation Before a DLC is set up using the mechanism in subclause 5.4.1, the TE and MS must agree on the parameters to be used for that DLC. These parameters are determined by parameter negotiation. [ETSI TS 101 369 V7.1.0, 5.4.6.3.1 ]
