Raspberry Pi 3 as an USB-MIDI over BLE-MIDI device
Senior Technical Software Manager at CESAR
Hi,
I'm getting correct connection in alsa-seq-autoconnect :
"Found source port ...
Found destination port "BLE-MIDI Device"
Connecting 20,0 to 129,0"
But on my iPad, when i send a midi sysex to the BLE midi port i get no answer and the reply sysex is not sent back to the ipad from the USB-connected midi device
Is there a way I can manually send note and velocity using any of the routine in Btmidi-server or alsa-seq-autoconnect? I'm trying to connect couple pushbuttons to the gpio pins and have them play some notes in garageband.
Hi:
I´ve installed on Raspberry Pi 1 B+, using a BLE USB dongle.
I´m able to start btmidi-server on RPi, connect with my iPad, using Set List Maker app.
I´m using another solution for USB MIDI routing - https://github.com/fralalonde/autoroute - it works perfectly, since you create a ALSA MIDI device that I can configure in autoroute service.
Some issues I´ve found:
The name of the service is not properly showed, i.e. "RPiBlue" on btmidi-server call, I see FC097FC4-9FD2-4E8F-A900-54D48F4F06FA
Short and individual MIDI messages like Note On, Note OFF, Controller are transported correctly. It´s working, congrats ! However:
If I send lot of Notes together at same time (~4) some of them are missed.
if I send more than one controller messages together in sequence, some messages are missed, adding 00 byte between each message is a workaround...
Seems some kind of buffer/message packing handling needed.
Are you facing same issues ?
Is there a tip to help me to find out these issues ?
Thanks!
Ps.: Sempre bom ver BRs por trás de projetos legais como esse.
Hello!
I'm trying to figure out how to compile your btmidi-server with bluez-5.52
.
I modified Makefile.tools and added what appeared to be the relevant parts from your Bluez fork (the if MIDI
statements). However I don't end up with a btmidi-server executable after making.
Can you suggest how best to compile btmidi-server with bluez-5.52
? Thanks!
Hi - Wondering if you think this should work on zero w?
I tried to build, and after resolving a load of dependencies and getting bootstrap-configure to run, I get some compilation errors on btmidi-server.
Any advice on building on pi?
How do I run both the btmidi-server and alsa-seq-autoconnect automatically when the raspberry pi starts? I have a bash script that will run both of them fine manually but it won't run if I put it in rc.local. Any better way to do it?
First of all, thanks for your great work! I was able to compile the code in RPi3 but not sure how to use it. I have 2 questions below:
What command do I need to run to make ble app(garage band) recognize the RPi3? I was able to run ./configure --enable-midi and was able to see my midi keyboard in the RPi3 using aseqdump -l. I was able to pair (bluetooth classic) the RPi3 using bluetoothctl as well but not sure what to do for iOS to recognize the RPi3 as midi BLE device.
Does btmidi-server run automatically when I run ./configure --enable-midi or do I have to start it somehow.
I'm very new to bluez/linux so thanks in advance for your help!
Hi
thank you for your code. I have a question.
I have compiled the code in Centos 7 without problems
When i connect my keyboard i see the message "Found source port LPK25 MIDI 1"..looks good
I have paired the linux box with ipad but when i start garageband i can't see any Midi Bluetooth LE device
any suggestion???
Luca
Hi,
Thank you so much for the cool code. Currently whenever I run the code, the device show up in iOS garage band as "A78AD39D-1053-xxxxxxx-xxxxxxx-xxxxxx". Is there any way to change that name to something more meaningful such as "Raspberry Pi BLE" or something?....
