I am sorry this has taken so much time, but I have been in various fights with Apple over Buster for the past few months. Finally, Buster 1.2.9 has been released to the app store. This should work bet

Buster version 1.2.4 was just submitted to the Mac App Store for review. This revision should fix the bug people are seeing with serial devices not being properly recognized in Catalina. -- Annaliese

This indicates a hardware issue. If there were a hardware issue, we'd have tons of folks complaining about bad hardware. We have been selling the ThumbDV at 460800 for years now with no issues on Mac,

#thumbdv

I am not aware of anyone using the library to communicate with the chip. I use standard tty IO with Buster and it works fine at 430800. I’ve also worked with the chip on Linux while doing some rewrite

#thumbdv

If you’re using a ThumbDV you are using the wrong serial port. You need to do something like: systemctl stop ambeserver@ttyS0 systemctl disable ambeserver@ttyS0 systemctl enable ambeserver@ttyUSB0 sys

That’s what I figured. The dumb author of this software didn’t know who to ask about preferred protocols to the XLX reflectors and assumed that DExtra would work fine and was the easiest. I’m sure at

I was at the APRS Summer Gather in North Bend, WA last weekend hanging out with the rest of the NW Digital Radio crew and a bunch of other ham friends, so I didn’t have a chance to commit the code and

You shouldn’t have to do anything but upgrade off the App Store. —Anna

Without the new code, Buster won’t even look for it. Hold tight and I’ll get a new version out. —Anna

John and I worked out some datasource issues and I’ll be releasing some code in the next couple of days that will hopefully include XLX reflectors. -- Annaliese McDermond (NH6Z) Xenotropic Systems mcd

Dick -- At startup time, the reflector protocol drivers load up a properties list (plist) file of what reflectors they able to handle connections to. That list is made up of an internal list that’s sh

Are you sure you have v1.2.1, the latest on the app store? There was a bug with entitlements that cause it to fail to be able to get the microphone device. — Anna

Buster tries to remember the last working setup and always use that if it can. That’s why restarting it doesn’t always help, because when you initially use the program, there is no good setup, so it c

Buster looks at the serial port, opens it, and tries to send an “reset” packet to the DVSI chip. It should hear a “ready” packet back if it’s successful and the DVSI chip is online. If the DVSI chip r

For those of you waiting on this fix, I submitted it to the App Store today. It will automatically release when Apple approves it, so you should be set. Expect it to be version 1.2.1. -- Annaliese McD

The start of every packet from the ThumbDV starts with a 0x61 byte. If AMBEServer cannot find that byte in any of the responses, it errors out. This is usually due to errors in AMBEserver by hand and

After a long hiatus, Buster v1.1 has been released on the App Store. This version should have improved stability on MacOS X Sierra and a couple of other bug fixes. Please use my GitHub issue tracker a
