We're happy to announce release 0.2.0 of osmo-fl2k. It contains the following main advancements over the previous 1.1.0:

• free zero-copy buffers in case of error
• fl2k_file: support reading from stdin
• avoid compiler warnings when using libusb >= 1.0.22
• add debian packaging
• fix sleep durations on Windows
• add I2C support
• Add workaround for Linux usbfs mmap() bug on ARM/ARM64
• avoid potential endless-loop in fl2k_file: check read return value before repeating
• fix segfault on exit: wait for sample worker thread before freeing buffers
• fl2k_tcp: fix segfault on exit: don't free buffer while lib still uses it
• make osmo-fl2k work again with Linux 5.5.0-rc6 or later (invalid USB endpoint sharing in descriptors)

We're happy to announce the release of rtl-sdr version 2.0.1 containing the following main advancements over the previous 0.6.0 release:

• work-around for Linux kernel mmap()-bug on ARM/ARM64
• disable usbfs zero-cop by default (may cause bus errors and has only marginal performance benefit)
• build fix for OpenBSD
• allow non-default GPIOs for bias-tee configuration
• rtl_biast command line tool
• fixed issues compiling on Windows with MSVC, CMake and NMake
• support for libusb on GNU/Hurd
• add IPv6 support to rtl_tcp
• modernize cmake (new minimum required version is 3.7.2)
• tuner_r82xx: fix short-write in r82xx_read()
• rtl_fm: add a new option to select 2nd direct sampling mode
• lib: Stop applying workaround for libusb < 1.0.9 (from 2012!)
• Fix signal handler from getting stuck in an endless loop
• add rtl-sdr blog v4 support
• add -D direct sampling flag to rtl_tcp

We're happy to announce that our recorded presentations of OsmoDevCall are now also published in our new @osmodevcall@tube.tchncs.de peertube¹ channel. A peertube channel has the advantage that it can be subscribed by interested people, as long as they have a user account in any fediverse/mastodon instance.

¹ Peertube is a federated, open source video sharing system built on Open Source Software using the ActivityPub protocol many people know from Mastodon. See https://joinpeertube.org/ for more information about it.

We're happy to announce the @retronetworking@tube.tchncs.de peertube¹ channel, which will be used to post videos related to retronetworking topics.

The initial content is timelapse videos of the recent activities around the Rescue of a Siemens EWSD exchange

We're happy to announce the next incarnation of RetroNetCall, the retronetworking oriented spin-off of OsmoDevCall

This time, there's no formal presentation. However, laforge (and maybe some others) can report on

• The rescuing efforts of an EWSD (digital telephony exchange) that was recently transported to its new home with jolly
• Some initial research into the BildTel_001, presumably the first ISDN video telephone in the German ISDN network

pySim-shell is getting initial support for talking to eUICC (the physical chip used in eSIM applications).

At this point this specifically means supporting the ES10x interface of GSMA Consumer eSIM (as well as GSMA IoT eSIM).

See https://asciinema.org/a/616888 for a quick demo of what is possible with current pySim-shell from master.
