LimeSDR Mini 2.0

by MKS

Hello, are there any known issues in using the LimeSDR Mini 2.0? I see that the original LimeSDR Mini is supported - there is published documentation on using osmocom-analog with it. Can I follow the same installation procedures using the LimeSDR Mini 2.0 as shown for the LimeSDR Mini? Thanks

Having trouble transmitting with USRP

by h416984j＠gmail.com

Hi, I have been interested in trying out Osmocom-analog's AMPS implementation. I purchased an Ettus B210 clone device and built osmocom-analog from source as described on osmocom-analog.eversberg.eu. Everything went well until I started the program and tried to transmit, I received no Tx (output) and the built-in graphs and visualizers had strange output unlike what was expected: https://imgur.com/a/Ghr1cju. I used Ubuntu 22.04 and UHD driver 4.7.0. I am truly at a loss at what is causing the strange output, I also tried launching with soapy and several other arguments. Additionally, the LimeSDR Mini V2 I had previously acted the same way as well, so I'm unsure what the problem is. Any advice will be appreciated, and more information can be provided. Thank you.

Problem getting AMPS to start

I am having a problem getting osmocom amps to successfully start. lsusb shows my B210 on Bus 3, Device 3. uhd is installed. uhd find devices shows: INFO] [UHD] linux; GNU C++ version 11.4.0; Boost_107400; UHD_4.6.0.0-141-g0f2007fc -------------------------------------------------- -- UHD Device 0 -------------------------------------------------- Device Address: serial: 191796 name: MyB210 product: B210 type: b200 I am attempting to start AMPS with: amps --sdr-uhd -k 334 -k 332 -p -d -F no --sysinfo sid=18 1234567890 The result is: DSENDER ERROR sender.c:240 No device for transceiver! There is more text before and after the above message. I can paste it if you like. But I think the problem is I am not using proper syntax to tell AMPS to use the my B210. I have tried SoapySDR and have received the same results. I would appreciate help in how I can properly tell the osmocom software to use my B210. Thank you very much, -Shawn

Osmocom discourse as alternative to mailing lists

by Harald Welte

Dear Osmocom community, while many people with a long history in FOSS development have no issues at all with mailing lists as primary form of engaging with their community, they have undoubtedly fallen out of fashion in favor of various chat/messaging systems or web based forums. In Osmocom, we've just launched an installation of the discourse forum software available at https://discourse.osmocom.org/ providing an alternative to our traditional mailing lists at https://lists.osmocom.org/ We're looking forward to see whether this web-based approach will facilitate more and/or other people to engage with the Osmocom developer/contributor community. Feel free to join and get the discussions started. If there's a need for more categories or sub-categories, just let one of the moderators know and we can help with that. The old mailing lists will continue to remain available for those who prefer them. -- - Harald Welte <laforge(a)osmocom.org> https://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

osmocom-analog to osmo-cc-sip-endpoint local server help

by admin＠ready100.com

osmocom-analog is working. osmo-cc-sip-endpoint is installed and working (i think) however, i'm not sure what my sip-endpoint command line should be... Everything is running on the same machine, I just want to connect my AMPS device to my local asterisk server. I have setup a user for the pbx using the phone number baked into the phone. I have a non standard port (ie not default) for my asterisk server. When I try to use command lines I've seen on the lists I just get: sip.c:1783 error : Failed to create SIP stack object I assume it's just because I have incomplete parameters. Can anyone help? I'm so close!

by stubbertville＠hotmail.com

Howdy! Im new to all this and I already have two AMPS cell phones, but I cant seem to find a cheap sdr I could use with them, the hack rf and lime sdr are either waaaay too expensive or waaaay too rare, any suggestions or help would be welcomed and appreciated!
