GNU Radio Code for Android Now Released
Back in November 2019 we posted how Bastian Bloessl (@bastibl) had teased us with his ability to get GNU Radio running on an Android phone. Now he has officially released his code to the public on GitHub. This is quite a remarkable development as you can now carry a full DSP processing suite in your pocket. In addition to the code, he’s put up a short blog post explaining a bit about the port. He notes some highlights of the release:
- Supports the most recent version of GNU Radio (v3.8).
- Supports 32-bit and 64-bit ARM architectures (i.e.,
- Supports popular hardware frontends (RTL-SDR, HackRF, and Ettus B2XX). Others can be added if there is interest.
- Supports interfacing Android hardware (mic, speaker, accelerometer, …) through gr-grand.
- Does not require to root the device.
- All signal processing happens in C++ domain.
- Provides various means to interact with a flowgraph from Java-domain (e.g., Control Port, PMTs, ZeroMQ, TCP/UDP).
- Comes with a custom GNU Radio double-mapped circular buffer implementation, using Android shared memory.
- Benefits from SIMD extensions through VOLK and comes with a profiling app for Android.
- Benefits from OpenCL through gr-clenabled.
- Includes an Android app to benchmark GNU Radio runtime, VOLK, and OpenCL.
- Includes example applications for WLAN and FM.
