A test for the BASIC Stamp 2 microcontroller
1. The Easy Bluetooth can communicate at numerous baud rates, and with many different
microcontrollers. This example uses the AppMod Header on the Board of Education, the BASIC
Stamp 2, at 9600 baud.
2. The easiest way to see in your code if a Bluetooth connection has been established is to wait for
a byte to be received. You can copy the program below into the BASIC Stamp Editor to ensure a
proper connection.
' {$STAMP BS2}

combyte
DEBUG "Use This Screen for Display",CR

SERIN RX, Baud, [combyte]
DEBUG combyte
LOOP
3. Download the program using Run => Run (ctrl + r) from the BASIC Stamp Editor
4. Keep Current DEBUG Screen open, and open another DEBUG Screen (ctrl +d) from the BASIC
Stamp Editor, and select TX COM that the Bluetooth module (refer to COM ports during Bluetooth
installation) is using; you should now have 2 DEBUG Terminal windows open. Click in the white
area of the DEBUG window of DEBUG Terminal 2 and press any key; if all the steps were
correctly done, the same key will be sent back to the DEBUG Terminal 1 window.
