Create a connection to a nearby Bluetooth device. In this example, the HC-06 Bluetooth module is configured as a loopback device.
device = bluetooth("HC-06")
device =
bluetooth with properties:
Name: "HC-06"
Address: "98D331FB3B77"
Channel: 1
NumBytesAvailable: 0
NumBytesWritten: 0
Show all properties
Write the values 1:10 to the device.
write(device,1:10)
Since the device is configured as a loopback device, the data you write to the
device is returned to MATLAB®. Read all the data.
read(device,10)
ans = 1×10
1 2 3 4 5 6 7 8 9 10

Write the string "helloworld" to the device.
write(device,"helloworld","string")
Since the device is configured as a loopback device, the data written to the device
is returned to MATLAB. Read the first five values of data as a string.
read(device,5,"string")
ans =
"hello"
Use the read command again to read the next five values of
data.
Bluetooth device connection, specified as a bluetooth object.
Example: write(device,10) writes to the Bluetooth connection device.
Numeric or ASCII data, specified as a 1-by-N vector of numeric values or as a
character vector or string scalar of text. For all numeric datatype
types, data is a row vector of values.
Size and format of each value, specified as a character vector or string.
datatype determines the number of bytes to write for each value
and the interpretation of those bytes as a MATLAB data type.
For any read or write operation, the data type is converted to
uint8 for the data transfer. After the transfer, the data type
reverts to the specified datatype.
Example: write(device,1:5,"double") writes the values
[1,2,3,4,5] as double data.
