Bluefruit LE MIDI problem

Post by szuecs »

Hi there,

Trying to get the MIDI example sketch working with the Bluefruit LE shield. I soldered up the board and plugged in into an Arduino UNO R3.

I uploaded the ‘atcommand’ and ‘bleuart_cmdmode’ sketches and they ran fine.

I downloaded the iGrandPiano app. I already had midimttr since I use it for another application.

midimttr sees the iGrandPiano app as a destination, but no BluefruitLE as a device. It’s just stuck on “Searching for Bluetooth LE MIDI devices…”

So sketch compiles and uploads fine. Doesn’t want to get into MIDI mode.

Thanks for any insight into the issue.

This is the output to the Serial Monitor:

OK, looks like the boards I purchased needed an update to the firmware. Once I did this things work fine. I figured newly ordered boards would have latest update.
