MIDI BLE example nRF52840 sending data

[Soojin]

Hi I'm doing the Bluetooth GATT: How to Design Custom Services & Characteristics [MIDI device use case] example
(https://www.novelbits.io/bluetooth-gatt-services-characteristics/)
And I want to send a random value (i/0 want to save a random value to the characteristic value.
But I cannot find where I should change the code!

Can someone tell me which part of the code I should look at if I want to change the value I am sending(i/o value that is saved as the value of the characteristic)??
Thanks

Hi Soojin,

The ble_midi_data_io_value_update() function (in midi_service.c) takes care of the value update in the novelbits example so maybe start there if you want to figure out how to change the i/o value. 

I would recommend looking at this example guide from nordic on MIDI, https://devzone.nordicsemi.com/nordic/short-range-guides/b/bluetooth-low-energy/posts/midi-over-bluetooth-le?CommentId=f116764b-41d4-4cf5-8839-5e4f664c27ee
