Member Data Documentation

enable_notifications

void(* MblMwBtleConnection::enable_notifications) (void *context, const void *caller, const MblMwGattChar *characteristic, MblMwFnIntVoidPtrArray handler, MblMwFnVoidVoidPtrInt ready)

Enables notifications for characeristic changes.

Parameters

context	Pointer to the context field
caller	Object using this function pointer
characteristic	Characteristic to enable notifications for
handler	Callback function for handling characteristic notifications
ready	Callback function to handle when the enable notify task is completed

on_disconnect

void(* MblMwBtleConnection::on_disconnect) (void *context, const void *caller, MblMwFnVoidVoidPtrInt handler)

Register a handler for disconnect events.

Parameters

context	Pointer to the context field
caller	Object using this function pointer
handler	Handler to respond to the disconnect event

read_gatt_char

void(* MblMwBtleConnection::read_gatt_char) (void *context, const void *caller, const MblMwGattChar *characteristic, MblMwFnIntVoidPtrArray handler)

Reads the value of the characteristic from the device.

Parameters

context	Pointer to the context field
caller	Object using this function pointer
characteristic	Gatt characteristic to read
handler	Callback function to handle the received value

write_gatt_char

void(* MblMwBtleConnection::write_gatt_char) (void *context, const void *caller, MblMwGattCharWriteType writeType, const MblMwGattChar *characteristic, const uint8_t *value, uint8_t length)

Writes the characteristic and value to the device.

Parameters

context	Pointer to the context field
caller	Object using this function pointer
characteristic	Gatt characteristic to write
value	Value to write as a byte array
length	Length of the byte array
