title: How to send serial data to a mac using the bluetooth serial profile
body: <p>I'm working on software that must receive and parse serial data sent over an rs232 connection. My macbook (running macOS High Sierra) doesn't have a physical serial port, but it does have a port listed as "Bluetooth-Incoming-Port". To my understanding, data can be sent to this port via bluetooth and received just as if it had been sent over a cable. I would like to send data (ASCII text) from my iphone to this port to test my software, but I can't figure out how to do this - all the tutorials I've found are oriented towards arduino setup.</p>
