2m DVAP Transmit Lockup Bug

There appears to be a known issue with the 2 meter DVAP locking up, stuck in transmit mode, after some hours of operation, especially on a busy reflector. Other users (via Pi-Star FB support group) have confirmed that this is unique to the 2m DVAP and does not occur with the 70cm DVAP. The same DVAP functions fine with alternative software such as DVAP Tool or condv and does not experience this transmit lockup. How can we get this looked at upstream so that it can be diagnosed and fixed?

I have run into the same issue before with other non Pi-Star installations of DStarRepeater/ircDDBGateway and reported it with no succes (ie DL5DI's OpenDV) fork. This was in January 2017.

Thanks for any assistance.

I too use a 2m DVAP, but as far as I know have never experienced any lockup, either with Pi-Star or any other Raspberry Pi software.

My DVAP is mounted directly on my R/Pi, uses the small stubby antenna, and is set to -10dBm output. I use WiFi and only have the power cable and a short (6") USB cable to the DVAP.

Perhaps the low power has something to do with it not locking up?

I seem to have solved the problem.

I upgraded the firmware to v1.7. This is not available from the official DVAP support site and I am not sure of its provenance, but I downloaded it from the Dutch Star website. Once I applied it the old DV Tools software would no longer work with it but it does with with DStarRepeater and therefore Pi-Star.

A couple of days later and I have observed no transmit lockups.

The firmware is available here: http://www.dutch-star.eu/software/

I also saw a Sourceforge page with the software, but I did not try it from this site:

https://sourceforge.net/projects/dvaputil/files/

Please only perform this update if you are confident that you know what you are doing and are willing to risk bricking your device. While I had no such issue I cannot guarantee your success.

The updated firmware is no longer on the DutchStar site as far as I can see - any chance of sending me a copy?
