MIDI over Bluetooth with ESP32

29 posts in this topic

Great work Thorsten !!

Side question, is it possible to hook ESP32 and STM32F4 cores with direct midi/UART connection (high speed without opto like I do between 3 STM core here)

And use it as a RTPM wifi bridge ?

Best

Or prepare the ESP32 as a SPI-MIDI slave like a kissbox?

Actually I wanted to provide SPI slave (see some postings above), so that the module can be connected to J28 instead of ENC28J60

But a UART connection is available as well - and the baudrate is configurable by default.

As long as you only need a point-to-point connection, UART is a good choice. But for accessing multiple ports (e.g. BLE and Apple MIDI) SPI would be better, because it considers multiple "cables".

Best Regards, Thorsten.

P.S.: in context of MBHP_MF_NG: only UART option will work, because SPI is already used for other purposes.

So meanwhile: is it worth replacing the PIC with the ESP? 

I'm designing a PCB for MF NG by myself. So if the PIC is outdated I'd upgrade to an ESP up front.
