Simulink Support Package for LEGO MINDSTORMS NXT Hardware
Send data to another NXT brick over the built-in Bluetooth device.
The model running on the other NXT brick must contain a Receive
via Bluetooth Connection block.
To establish multiple channels between the two NXT bricks, use
multiple pairs of Bluetooth blocks, and set the Mailbox parameters
for each pair to a unique number. This approach cannot be used to
establish communication between more than two NXT bricks.
The maximum size for the block input is 64 bytes. The supported
data types for the block input are uint8, int8, uint16, int16, uint32,
int32, single, and double.
Because External mode relies on a Bluetooth connection between
the host computer and the NXT brick, you cannot use External mode
with models that contain a Send via Bluetooth Connection block or
a Receive via Bluetooth Connection block.
Set the Mailbox parameter in both the Send via Bluetooth
Connection and Receive via Bluetooth Connection blocks
to the same number.
