Butterfly traffic display: firmware update available

I've updated the Butterfly traffic display firmware;
fixed a number of bugs and it now works properly with
newer FLARM protocol. Lots of Butterfly displays were
purchased with the initial batch of USA PowerFLARM cores.

Special thanks to Kirk, Dan, Uli, and Cliff for the help
testing numerous releases, Patrick for loaning me a test unit,
and to the Butterfly guys for sending me the source code to update!

Update as follows:
- format a USB stick
- in your browser, left-click on link below
- save page as bfd_4_0.bfw onto USB stick (no TXT suffix or other bollix)
- with power off, plug stick into flarm core
- while depressing butterfly button, power-on flarm/butterfly
- Butterfly will initially show "Waiting"...
- Butterfly should start loading within 15-30 seconds
- Wait a couple minutes and you should see Butterfly start with new firmware

Enjoy,
Best Regards, Dave

So "newer FLARM protocol" means the display will become compatible with the version 8 and/or 9 of the PF protocol? Wonder if you can elaborate on what one gains by moving from protocol 7 to either 8 or 9. thanks!

FLARM provides extremely good backwards compatibility;
a display device can request an older protocol and it just works.
Butterfly code had a few minor issues that cropped up over the years,
like parsing assumptions that used to be OK but became invalid over time.
Butterfly now requests version 7 which all operational devices support.
Details of changes in 8 and 9 are in the protocol documentation chapter 6;
not important for most users (especially in USA) nor for Butterfly.

Hope that helps!

Thank you Dave!

Dave,

First, thanks for all this work for the soaring community.

Questions - Why didn't Air Avionics (nee Butterfly Avionics*) resolve these issues rather than you needing to step in? Has the company orphaned software updates for the entire line of Butterfly devices (which I think has been sold as late as 2017)?

I get that no device's support goes on forever. But to me this doesn't lend confidence with this manufacturer.

Your take?

Thanks again,
John

Actually, a manufacturer releasing the source code to a 3rd party to update an obsolete product is highly unusual, and exemplary support. It is almost unheard of. Now I wish Air Avionics would do that for the Butterfly vario (still the best in the world).
