Logging functions Q's
by scancaster＠scancaster.net 23 Jul '19

23 Jul '19

Before I go down a hole and end in a dead end.... I have some questions on using the -L option for "logging." Logging in my universe means logging the audio to Dictaphone/tape/disk/CD/what ever physical media... NOT the -v option, thats a log, not logging! :) ;) So after reading about 30 different files on this -L option, it appers that it will act as A LOGGING RECORDER and RECORD the audio to disk... Great! What I am after is to record UNKNOWN GROUPS for analysis for ID purposes.... My question(s) are what options are used with this for: rx.py trunk.tsv whitelist.tsv blacklist.tsv ie: rx.py example ./rx.py --args 'rtl' -N 'LNA:47' -S 2400000 -f 8xx.xxxxe6 -o 25000 -q 72 -L 4 -v 10 -T trunk.tsv -V -2 -U -O loop0 -M mysystem.json -l http:192.168.0.26:8080 -x 3 2>> stderr.2 trunk.tsv then REQUIRES a "center frequency" for the system... 8xx.xxxx based on the channels of the system... I've determined this for this system, and it will just fit the way this is setup. This will then RECORD the various groups that are NOT BLACKLISTED to disk as WAV's from what I understand... Correct???? Ie: OP25 tunes to a group, it records it. Anything that is exlusive of each other on this -L option with other optons for rx.py???? Any thing I am missing in this????? Goal is simple to log any group I've not blacklisted as known user/use.. Thanks.

A couple Q's - RID Aliases? CC Data
by op25＠zellners.com 26 Feb '19

26 Feb '19

In reviewing the various setups of trunking_file.tsv, id_file.tsv etc... and looking over various documentation, I am not seeing a means to do RID(LID) or Radio ID aliasing... I am I missing this some place??? The systems can be setup to alias out $47E136 as "Helo1" etc... The systems have places to do this from the start and update from consoles etc... Any way to do that in OP25???????? ie: rid.tsv 47e136 Helo1 47e137 Helo2 etc... Turning RID into an alias would be a plus to ID units... ie: Ladder1, Ladder1_Portable, FF152521, etc.. Many of these are pretty static.. now some depending on you agency(s) may not be... in on a particular group would need some updates each year, as they change based on a progression system. CC Data is there some sort of aggregate that determines the quality of the CC data coming out???? That can accessed programmatically??? Or maybe that question is better referenced as is the there something that documents the API to OP25 that the various python scripts are using to possible do what I want... The plots are not useful as I desire text data to use in another place.... So I guess something that documents interacting with the underlying mechnations of OP25 would probably help to do what I am after with the CC. Thanks.

boatbod - github - NO issues link??? Bug report...

Trying to report an bug/issue, but https://github.com/boatbod/op25/issues doesn't work, goes to wrong place, and there is no link on the main page of it. BUG: Program dies due to uncaught exception Details: When updating the metadata/"tags" to IceCast, if the connection has died for some reason, LAN goes down, what ever... There is an uncaught exception which will kill OP25 running. 1547434556.069343 set tgid=53, srcaddr=0 Exception in thread Thread-4: Traceback (most recent call last): File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner self.run() File "/home/pi/op25/op25/gr-op25_repeater/apps/icemeta.py", line 60, in run self.send_metadata(self.msg.to_string()) File "/home/pi/op25/op25/gr-op25_repeater/apps/icemeta.py", line 77, in send_metadata r = requests.get((requestToSend), auth=("source",self.cfg['icecastPass'])) File "/usr/lib/python2.7/dist-packages/requests/api.py", line 70, in get return request('get', url, params=params, **kwargs) File "/usr/lib/python2.7/dist-packages/requests/api.py", line 56, in request return session.request(method=method, url=url, **kwargs) File "/usr/lib/python2.7/dist-packages/requests/sessions.py", line 488, in request resp = self.send(prep, **send_kwargs) File "/usr/lib/python2.7/dist-packages/requests/sessions.py", line 609, in send r = adapter.send(request, **kwargs) File "/usr/lib/python2.7/dist-packages/requests/adapters.py", line 487, in send raise ConnectionError(e, request=request) ConnectionError: HTTPConnectionPool(host='audio.myserver.net', port=8000): Max retries exceeded with url: /admin/metadata?mount=/RedactedFeed&mode=updinfo&song=[idle] (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x691bc8d0>: Failed to establish a new connection: [Errno 110] Connection timed out',)) This is not about an issue with the connection, there was, and eventually led to the Pi being replaced as faulty or melted down from use of OP25 :) ;) If the max retries is exceeded or any error where the update fails, it shouldn't kill OP25 from running... Glad to add to the issues section of github, but see top part, for some reason its not there. (??????)

whitelist file changes?
by John Ackermann N8UR 23 Jan '19

23 Jan '19

Hi -- After a few months away, I fired up the op25 machine today and updated to the latest boatbod version. Great improvements, especially the web interface! I'm having a minor issue, though. It seems as though my whitelist file is no longer working. The log shows that it's being read, but doesn't list the included groups, and I'm hearing lots of traffic from TGs that aren't on the list. Has anything changed in whitelist handling? (My wl file is in two column format: TGID<tab>TAG which worked after patches that Graham applied last year.) And, by the way, thanks Graham for fixing the statistics.sh script; I never quite got around to that after the log file format changed. Thanks, John

Audio Dies?????
by scancaster＠scancaster.net 08 Jan '19

08 Jan '19

I am noticing as I set this up and letting it run that after some point the audio dies on loop0, thus the feed is silence, nicht gut! Any one else seeing this???? This is both on a PI3B+....and an old dual core laptop..... The laptop has a -V10 and I tail the output log, and the decode traffic is still good for the CC, no errors in it... I can see TG's appear in the tags for the groups from both, just no audio.... :( :( Simply killing rx.py, restart, audio comes back,.... Doesn't seem to be much to tie it down... runs overnight, no issues, I even restarted OP25 on both setups to make some changes to use the TG priority option... and that was about 10 or so hours of run time.... as some point after the 5-6 hour time period it die{d|s} .. can't be exact as real work gets in the way... Dongle related?? But if it was that would expect to see CC decode errors etc... but I see CC decodes stream, and then decodes for data when voice is active..... ? ? ? Any one else seeing this ??? Any corrective action???? ? ? ? ? ? ?? ? ? ? ? ? ? THANKS!

Audio to Darkce/IceCast Server - No audio???? No tags, Local audio good.
by op25＠zellners.com 05 Jan '19

05 Jan '19

OK... I've put my RPi3B+ to work... Raspbian Image, updated, fully loaded.. (NOT NOOBS, this is just Raspbian Full ) Run through the install setup for OP25 from: https://www.hagensieker.com/wordpress/2018/07/17/op25-for-dummies/ Did this for my reclaimed laptop and this Pi... OP25 working on both... Local audio good on both. Tracks the PII system I need to put under review... So that works good.. The problem is feeding audio to my IceCast server.. :( :( :( I installed a MP3 capable Darkice with its deps... its starts up fine.. The feed appears on my server I am using the info at https://www.hagensieker.com/wordpress/2018/07/20/op25-raspberry-pi-streamin… I created /etc/asound.conf and /etc/modprobe.d/bcm2835.conf I rebooted the Pi rather than any reloading of things, to ensure that loopback created and loaded etc... For the ALSA Loopback etc. info and setup..... so is the ALSA loopback setup???? /darkice $ cat /proc/modules | grep snd snd_aloop 24576 0 - Live 0x7f3a6000 snd_bcm2835 32768 1 - Live 0x7f399000 (C) Check! Pi audio and ALSA loopback... CHECK CHECK! snd_pcm 98304 2 snd_aloop,snd_bcm2835, Live 0x7f138000 snd_timer 32768 1 snd_pcm, Live 0x7f11d000 snd 69632 6 snd_aloop,snd_bcm2835,snd_pcm,snd_timer, Live 0x7f102000 ALSA seems to be a dark arts thing.. I use some plugins on another setup to create L/R into separate feeds into darkice and that works great.... so I took it this loopback thing would do the same... Seems the loopback exists....from: ~/darkice $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: ALSA [bcm2835 ALSA], device 0: bcm2835 ALSA [bcm2835 ALSA] Subdevices: 7/7 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 card 0: ALSA [bcm2835 ALSA], device 1: bcm2835 ALSA [bcm2835 IEC958/HDMI] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Loopback [Loopback], device 0: Loopback PCM [Loopback PCM] Subdevices: 2/2 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 card 1: Loopback [Loopback], device 1: Loopback PCM [Loopback PCM] Subdevices: 2/2 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Loopbacks!!!!

So the audio is not piped through some where????? I figured if it was a issue with audio, tags would come through with out the audio... ./rx.py --args 'rtl' -N 'LNA:19' -l http:192.168.0.28:8080 -S 2400000 -f 8xx.xxxxe6 -o 25000 -q 26 -T trunk.tsv -V -2 -U -W 127.0.0.1 2> stderrstream.2 Watching the http output I see data come in, TSBK count goes up, TG's appear etc... NO AUDIO :( on the feed, WITH tags.... :) Local audio comes out the speakers.... So audio is recovered and in good quality even for a Pi.. Any hints, clues? ?? ? I've tried a couple of different setups for the loopback with an .asound.rc in the /home/user, used loop1, hw:1,0, hw:1,1 etc. tried as 2 channel audio v. single channel audio in darkice... still silence is not golden.... :( Any hints on getting the loopback audio working?? ? ? ? ? I might try it on the laptop setup too to see if its a Pi thing... My hunch is the magic dark arts of the right ALSA name for where the audio is at is wrong in the darkice config....but I've tried everything I can think of Thanks.
