I can confirm that if I send the sysex out of the Teensy using serial midi over a 5-pin DIN cable, rather than USB, everything works just fine. In that case I used an external device to translate the 5-pin din signal...
There seems to be some confusion.
The E32, E22 and E220 are all Ebyte modules.
The E32 is the original. Then came the E22 which was said to be improved over the E32. This (the E22) was said to have intermediary...

What is the servo doing that is wrong? I see you are going from 0 to 180 (180 steps x 0.015 = 2.7 seconds, assuming the servo can keep up with that)

I use both, the xxx30 is a high power (1W unit / 30 db) device. It has crazy good range and mine works even with poor line of sight. It will consume some 800 ma when transmitting, the xxx20 is a 100 mW unit and while...

Seems the 16 bit dac has become rare? I’m looking for some kind of breakout like a pmod board. I need a real dac that gives me a voltage for a number, not a stereo audio stream.
Thanks for the thread. I have a very similar problem, but on Teensy 3.6 (using midi Ox). My synth's sysex messages are about 1200 bytes long, and after adjusting max limits in the library files, I can get single message...

I can't answer about the software side, as I've never used Rust.

Another question I have would it be better to use the E32-900T30D wireless or the E32-900T20D LoRa module both UART and both seem to fit the bill. Again any advice would be welcome.
I designed one in FreeCAD, since I couldn't find one to buy. A helpful person will print it for me from ABS. Should be close enough. If not, I will alter it.
