Hi, I'm working on implementing Bluetooth MIDI for my controller. I've read the spec (version 1.0) and got it set up transmitting MIDI via BLE.

However, I want to explore the possibility of also receiving MIDI. I see no mention of that in the spec. Is this currently a possibility?

I'm testing on OSX, using Audio MIDI Setup to connect to my device. The device appears only as an input, not an output. Is there anything I can configure on the device to make it appear as input and output?

Edit: I've figured out what the problem was. I forgot to set the "write without response" property of the I/O characteristic. Setting that property, I can send MIDI messages to the device via BLE.
