Testing a Bluetooth Module

Here's how to test a Bluetooth module.

• Short TX with RX on the module.
• Power it up with 5V. ("+" and "-").
• Bind to computer's Bluetooth.
• Open a serial terminal (screen on Mac, putty on Windows)
• No need to set baud rate, any rate will work.
• Type on the console.  Every character will echo back since TX and RX are shorted together.
