So far Apple has not resolved the BLE transmit error with their latest iOS betas.
Write Apple if you have not done so already.
Have a friend with an Android phone or perhaps a Lenovo tablet help you to update your MM (as per MarkF48 in post 47, above).
Good news and bad news.
Good news: Apple released iOS and iOS iPad 26.3 developer betas 3 just now. The public beta 3 won’t be too far behind and that will most likely be followed by the official release of iOS 26.3 in two or three weeks.
Bad news: MIDI Maestro still not able to complete a firmware or Default Modes update with the pedal.
I just submitted another report to Apple via their Feedback app.
In the same boat here. Bricked since December and frustrated as well. My experience tells me that Apple never fix what they change, which means, SS should get a different programmer to work out changes and stop pointing fingers. Having been part of developing apps for a number of companies in past there has always been a work around. I hope this can be the case here. Being down for 2 months is unacceptable using the current IOS 26.2.1 I would think there would be a sense of urgency specially with BB2 release.
iOS update 26.2.1 dropped. Still showed transmission error on the midi Maestro app. Only tried the first firmware update on the app it didn’t cause a brick but still got the error.
iOS 26.2.1, released in late January 2026, primarily introduced support for the second-generation AirTag, featuring improved Precision Finding, alongside various, unspecified bug fixes
. Despite being a minor update, it reportedly included over 60 system binary changes, covering camera/video pipeline tweaks, audio firmware rebuilds, and updated Bluetooth firmware.
iOS 26.3 Release Candidate was posted 02/04/2026 and it does not fix the Transmission Error problem.
