The TT455-RT-238 holds 2 comports. You can receive the bluetooth signals on both comports.
For example you can trigger the TT455-RT-238 by bluetooth signals on comport1 (pin 7 and 8)
and let the TT455-RT-238 communicate with or control another product on comport 2 (pin 2 and 3).
With RS232 breakout interfaces like the shown below, you can easily connect 3 products by a few
wires and a screwdriver. See example on next page.
