I am currently working on a laser harp and have redesigned some things.
I know that it is possible to program and arduino over bluetooth, and that is all I want to do in terms of bluetooth. I plan on using this module from SparkFun: https://www.sparkfun.com/products/12577
This would of course attach to the TX and RX pins on the Mini. However, for the harp to work, I have to send information over the TX pin to the MIDI output. The MIDI will not use the RX line at all.
Will this be an issue if I am only using the module to program the Mini (i.e. only TX to MIDI during operation).
Thanks so much in advance :D
