The other hardware devices are supported by an OOT (out of tree) module
called gr-osmosdr. When you build and install the module, it adds it's
own sink and source blocks to GNU Radio.

Here's an example of devices enabled/disabled on my computer when I
build the module. This list is generated during the cmake portion. I
have a Nuand bladerf and an Ettus Research B210.

Hi there,
I have some questions about the firmware for other hardware device
except USRP.
1.I only found “gr-uhd” firmware for Ettus USRP from GNU radio source
codes. I am curious how other hardware devices ex. HackRFs works with
GNU Radio without official support firmware? For example, how to
create HackRF’s own source and sink block while USRP has “gr-uhd” with
its own source and sink blocks in it ?
2.For GNU raido, I understand python is for GUI, data flow and graph
and C++ is for algorithm implementation for each block. But I don’t
understand how user’s input arguments or parameters are transmitted to
hardware, what is the interaction between source, sink blocks and
hardware module. What kind of interface that a hardware developer
should provide?
If anyone could share some instructions or examples, I will appreciate
a lot. Thanks in advance.
