"UNHANDLED PACKET type: V" while transmitting from Xastir #11

Hi,

I'm working on a APRS-related project on Raspberry Pi powered by Archlinux ARM - extmodem is much more better at decoding real APRS packets recorded from radio than soundmodem while using cheap, chinese USB cards, but I have other kind of problems:

After running Xastir, logs from debug instance, executed in this way: /usr/bin/extmodem --audio-backend alsa --agwpe-tcp-port 8000 --kiss-tcp-port 6666 --ptt-mode null -s 48000 --in-chan 1 --t-chan 2 --debug --alsa-device "plughw:0,0"

Results in:

AGWPE New TCP connection, 1 total.
AGWPE new data 108
AGWPE new frame kind: R
AGWPE new frame kind: G
AGWPE new frame kind: k
AGWPE new data 92
AGWPE new frame kind: V
AGWPE UNHANDLED PACKET type: V

I configured Xastir to use AGWPE without success - every time I click "Transmit now!" or trying to send any message, I receive that error in log.

Have you discovered any successful way to connect extmodem to Xastir?

If it might be useful - aplay -L output:

Hi! You should upgrade your extmodem version. V frames support for xastir was added less than a month ago.

That's true, today compiled version works with Xastir and it is possible to decode frames even from webSDRs. Thanks for help and maintaining such a great project!
