Function Documentation

bool_t bluetooth_connect	(	bool_t	as_slave,
		char *	p_pin,
		uint8_t	device,
		uint32_t	timeout_ms,
		bool_t	reconnect
	)

Try to connect to another Bluetooth device.

Parameters:

	as_slave	true for connecting as slave (passive), false for master.
	p_pin	ID as ASCII string.
	device	Number of the device (1..8) to connect to (master mode only).
	timeout_ms	Time (ms) to wait (block) for a connection.
	reconnect	Keep a background connection "thread" running (slave mode only).

Returns:

true if a connection was established, false otherwise.

Todo:

Implement master mode.

void bluetooth_get_module_info

(

void

)

Get some information concerning the Bluetooth module.

Returns:

true if a connection exists, false if not.

Todo:

Format the module info in some structure.

Definition at line 152 of file bluetooth.c.

bool_t bluetooth_init

(

int

baudrate

)

Initialize the Bluetooth driver.

Parameters:

baudrate

Speed of the serial port that talks to the BT module.

Returns:

true if the initialization went well, false otherwise.

Definition at line 45 of file bluetooth.c.

bool_t bluetooth_is_connected

(

void

)

Check if this device is connected.

Returns:

true if a connection exists, false if not.

Definition at line 139 of file bluetooth.c.

void bluetooth_power

(

int

power

)

Switch module power on or off.

Parameters:

power

BLUETOOTH_OFF or BLUETOOTH_ON.

Definition at line 32 of file bluetooth.c.

uint8_t bluetooth_scan

(

void

)

Do a search for other Bluetooth devices.

Returns:

the number of devices found.

Todo:

Make more useful.

Definition at line 99 of file bluetooth.c.

int bluetooth_send	(	char *	p_data,
		int	data_size

Send data over the Bluetooth connection.

Parameters:

	p_data	Pointer to the data to send.
	data_size	Number of bytes to send.

Returns:

true if a connection was established, false otherwise.

Todo:

Implement. While doing that, implement also a receive function.

Definition at line 86 of file bluetooth.c.

bool_t bluetooth_set_friendly_name

char *

p_name

)

Set the human readable name of the Bluetooth device.

Parameters:

p_name

Friendly name as ASCII string (16 characters max).

Returns:

true if name was set, false otherwise.

Definition at line 59 of file bluetooth.c.
