SDRplay rewrite w/RSP2
by Jeff Long 02 Jan '18

02 Jan '18

I picked up a SDRplay RSP2 recently, and the gr-osmosdr support needed some work. Here's a rewrite that works with RSP2 and has other improvements. When the RSP1A comes in, I'll finish support for that. No plans to pick up a RSP1, but someone can see if this works if interested. This was tested against the Nov 2017 binary blob. https://github.com/willcode/gr-osmosdr/tree/sdrplay2 ===== Complete rewrite of sdrplay support - Supports RSP2 - Will support RSP1A when hardware arrives - RSP1 is untested - Uses streaming callbacks instead of polling - Tuning, gain control imporoved, AGC supported - Better performance (one less layer of buffers)

OsmoDevCon 2018 schedule planning
by Harald Welte 06 Dec '17

06 Dec '17

Dear Osmocom Community, [please respect the Reply-To and post all follow-up discussion to this to openbsc(a)lists.osmocom.org, so we avoid having long threads cross-posted to several mailing lists.] Like every year in early December, it is time to discuss as schedule for OsmoDevCon in the upcoming year. Note: Ths is about OsmoDevCon, the more private meeting of developers, *NOT* about OsmoCon, the public conference. == When, Who, Where == I propose the following date for OsmoDevCon 2018: April 20 - April 23rd, 2018 * Who: Active developers/contributors of Osmocom projects (as usual) * Where: IN-Berlin, Berlin (as usual) Please let me know ASAP if that proposed date works for everyone who'd want to attend. We can still change it now, but I would want to nail down the date pretty soon. == Format == After the experiment of reducing from 4 to 3 days last year (due to OsmoCon), we will again go for *four days* in 2018. However, we should clearly divide the days in a way that e.g. "GSM/3G" topics are on two days, while SDR+Other topics are on the other days, so people not interested in some topics can skip one or two days, as needed. We could even divide it further like: * 1 day 3GPP RAN (osmo-bts, osmo-bsc, osmo-pcu, virt_phy, fake_trx, ...) * 1 day 3GPP CN (osmo-msc, osmo-hlr, osmo-sip-connector, nextepc, etc.) * 2 days misc Regards, and looking forward to meeting you [again] in 2018, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
