[PATCH] Fix application hang on USB transfer errors
by Ramon Smits 27 Jan '26

27 Jan '26

Hello, I'm submitting a patch that fixes a critical issue where applications using rtlsdr_read_async() hang indefinitely when USB transfer errors occur. ## Background I encountered this issue while running long-term monitoring with rtl_fm for FLEX paging signals. When the RTL-SDR dongle would shift slightly in the USB socket (causing USB transfer errors), rtl_fm would hang indefinitely instead of exiting cleanly. ## Root Cause The problem occurs in two parts: 1. The _libusb_callback() function calls rtlsdr_cancel_async() from within the libusb event handler callback. This creates a race condition where dev->async_cancel is modified while libusb_handle_events_timeout_completed() is actively using it as a parameter, leading to unpredictable behavior. 2. Even when the dev->dev_lost flag is set, the async read loop doesn't properly exit, and applications like rtl_fm have no way to detect that the device is lost. ## Solution The attached patch: - Removes the problematic rtlsdr_cancel_async() call from the callback - Adds detection of dev->dev_lost in the main event loop to properly transition to RTLSDR_CANCELING state - Makes rtlsdr_read_async() return -1 when the device is lost - Updates rtl_fm to check the return value and terminate gracefully ## Testing Tested with RTL2832U dongle (FC0012 tuner) by deliberately triggering USB errors through physical movement. The applications now terminate cleanly with an appropriate error message instead of hanging indefinitely. Normal operation (Ctrl+C termination) continues to work correctly. This fix makes rtl-sdr more robust for long-running monitoring applications and deployment scenarios where physical interference might occur (e.g., Raspberry Pi installations). Please review and consider merging. Best regards, Ramon Smits

Fwd: Raspberry Pi 5 + RTL-SDR Blog V4 – rtl_* CLI tools produce zero output
by Bodó Richárd 03 Jan '26

03 Jan '26

Subject: Raspberry Pi 5 + RTL-SDR Blog V4 – rtl_* CLI tools produce zero output Dear Developers, I would like to report a reproducible issue observed with a Raspberry Pi 5 and an RTL-SDR Blog V4 device. *Hardware setup:* Raspberry Pi 5 (8 GB) RTL-SDR Blog V4 Direct USB connection (no external hub) Adequate power supply (official Raspberry Pi 5 power supply) *Software environment:* Raspberry Pi OS 64-bit (Bookworm) rtl-sdr package (rtl_sdr, rtl_fm, rtl_power) librtlsdr installed via distribution packages Fully updated kernel and system *Issue description:* rtl_test -p runs successfully USB streaming is active and samples are reported PLL lock messages are shown and the device appears stable *However, the following CLI tools produce no output data:* rtl_sdr rtl_fm rtl_power Output files remain at 0 bytes Processes run without errors, but no IQ samples or audio data are produced *Important observation:* The same RTL-SDR Blog V4 device works correctly on Raspberry Pi 3 and Raspberry Pi 4 systems using the same software stack. *Conclusion:* Based on testing, this appears to be an interaction issue between the Raspberry Pi 5 USB subsystem and/or kernel, librtlsdr, and the RTL-SDR Blog V4. Since rtl_test confirms that USB streaming is functional, the problem seems to occur at the level of sample delivery or processing in the CLI tools. I am happy to provide logs, detailed version information, or perform additional tests if required. Thank you for your time and for maintaining these tools. Kind regards, An RTL-SDR user P.S. My original goal was to develop an Airband (voice) scanner application with the help of ChatGPT, capable of scanning and monitoring airband frequencies. Neither the RTL-SDR Blog V3 nor the V4 worked as expected on the Raspberry Pi 5 during this effort. Based on recommendations, I specifically purchased an RTL-SDR Blog V4 because it was expected to be better aligned with the Raspberry Pi 5 USB implementation. This report is the result of several days of systematic testing and comparison across different Raspberry Pi models. The device enumerates correctly on USB and remains stable during operation. rtl_test confirms continuous sample streaming, indicating that bulk USB transfers are functional. No kernel errors, USB resets, or xHCI faults are observed in dmesg during runtime. The issue appears after device initialization, at the stage where librtlsdr-based tools should consume and process the incoming samples. USB-related kernel and firmware boot parameters were reviewed and adjusted via /boot/firmware/cmdline.txt, including settings related to USB behavior and buffering; these changes did not alter the observed issue. This suggests a possible interaction issue between the Raspberry Pi 5 USB/xHCI implementation, kernel behavior, and librtlsdr buffer handling rather than a physical USB or power problem uname -a lsusb lsusb -t dmesg | grep -i usb rtl_test -p rtl_sdr test.iq rtl_fm -f 118M -M am -s 240k - rtl_power -f 118M:137M:25k test.csv I did not purchase the Raspberry Pi 5 and the RTL-SDR Blog V4 as experimental or disposable hardware. This report is submitted in good faith, with the expectation that this platform can be made fully functional through proper investigation and resolution

rtl_fm Change cb transfer status: X, canceling...
by Ramon Smits 26 Dec '25

26 Dec '25

I occasionally get the error "cb transfer status: 1, canceling...". This usually is because something bumped my pi causing the RTLSDR dongle to move. rtl_fm nicely emits to ERROUT but remains running. I think this is likely an error. I would expect the process to die in this state. Is this reasoning correct? I made a change with claude.ai , it removed invoking `rtlsdr_cancel_async(dev);` === Why this fixes the halt: The callback was calling rtlsdr_cancel_async() while already executing inside the libusb_handle_events_timeout_completed() loop (line 1924), which would modify the dev->async_cancel flag that the event handler was actively monitoring. This created a deadlock/race condition. Now the callback simply sets the dev->dev_lost flag, and the main event loop at line 1961 properly detects this condition and breaks out cleanly, allowing normal termination to occur. The process should now terminate correctly when USB transfer errors occur. === The change is available at https://github.com/osmocom/rtl-sdr/compare/master...ramonsmits:rtl-sdr:rtls… Does this change make any sense? I have not fully tested this as I'm new to this project and somehow need to build this and deploy on my pi4 which I need to figure out. Any help appreciated! -- Ramon

deadline extension: FOSDEM 2026 (Feb. 1 2026): call for contributions on SDR/DSP (deadlineDec. 1 2025)
by jmfriedt 17 Nov '25

17 Nov '25

The Software Defined Radio/Digital Signal Processing (SDR/DSP) devroom is being organized for the 2026 FOSDEM held in Brussels (Belgium) Sunday Feb. 1, 2026. Any topic or achievement from the last year that you would be proud to share with the community? A few slots for the SDR/DSP devroom are still available, so the submission deadline is extended by a couple of weeks. We are seeking contributions discussing FOSS software for (radiofrequency) discrete time digital signal processing/software defined radio (SDR) including digital communication and data integrity (CRC calculation, Forward Error Correction -- FEC), communication channel characterization, navigation and positioning, target ranging and velocity measurement, and signal characteristics extraction from raw IQ collected from single or multiple antennas, as well as software frameworks easing such applications including GNU Radio, FutureSDR, Pothosware or custom frameworks. Novel openhardware description, possibly including the latest acceleration peripherals including FPGA and GPUs (or others), is encouraged, especially if using FOSS frameworks, but maybe also demonstrating how a radiofrequency grade oscilloscope can make an excellent (discontinuous stream) SDR receiver. Proposals should be submitted through https://pretalx.fosdem.org/fosdem-2026/ December 1st at latest, or 2 weeks from now. See you in Brussels, Jean-Michel

[Patch][Add] Support for the new HydraSDR
by sebastien.dudek＠penthertz.com 22 Jun '25

22 Jun '25

Hello, I hope it will go in the right place, here you can find a patch adding HydraSDR device support that upgrades the AirSpy R2. I had to create wrappers around GPIOs definition as putting the headers in namespace was a failure at run time. Indeed, the GPIOs have same references for now and this is the only clean way I've found to support both AirSpy and HydraSDR without disabling one of each. Please find the patch here that is also directly available and working on rfswift.io through this repo https://github.com/PentHertz/gr-osmosdr: ############################################################################ diff --git a/AUTHORS b/AUTHORS index 2fd882c..590b6db 100644 --- a/AUTHORS +++ b/AUTHORS @@ -7,3 +7,4 @@ SDRplay Ltd.

osmocom sink issue in GNU Radio 3.10.7
by edwar ewer 14 Feb '25

14 Feb '25

Dear gr-osmocom developers, I have a project that uses Jetson Xavier NX and BladeRF 2.0 to transmit and receive radar signals. I decided to use GNU Radio and gr-osmocom to do that task. Unfortunately, I encountered an error that, I think, GNU Radio failed to read all the parameters. This is the first time that I face this kind of error. I have been using GNU Radio for a while in a PC or Raspberry Pi but never see an error like this. Do you have any idea where is this error coming from and how to deal with it? Your suggestions are highly appreciated. Thank you. Best regards, Edwar [image: Screenshot from 2025-02-14 10-52-25.png] in osmocom sink and source.
