== `osmo-trx-uhd` for UHD based Transceivers
|
|
|
|
This OsmoTRX model uses _libuhd_ (UHD, USRP Hardware Driver) to drive the
|
|
device, that is configuring it and reading/writing samples from/to it.
|
|
|
|
So far, this backend has been mostly used to drive devices such as the Ettus
|
|
B200 family and Fairwaves UmTRX family, and used to be the default backend used
|
|
for legacy @osmo-trx@ binary when per-backend binaries didn't exist yet.
|
|
|
|
Any device providing generic support for UHD should theoretically be able to be
|
|
run through this backend without much effort, but pracitcal experience showed
|
|
that some devices don't play well with it, such as the LimeSDR family of
|
|
devices, which showed far better results when using its native interface.

_osmo-trx.git_.

== `osmo-trx-lms` for LimeSuite based Transceivers
|
|
|
|
This OsmoTRX model uses LimeSuite API and library to drive the device, that is
|
|
configuring it and reading/writing samples from/to it.
|
|
|
|
This backend was developed in order to be used together with LimeSDR-USB and
|
|
LimeSDR-mini devices, due to to the poor results obtained with the UHD backend,
|
|
and to simplify the stack.

[[backend_usrp1]]
|
|
== `osmo-trx-usrp1` for libusrp based Transceivers
|
|
|
|
This OsmoTRX model uses the legacy libusrp driver provided in GNU Radio 3.4.2.
|
|
|
|
As this code was dropped from GNU Radio at some point and was found very
|
|
difficult to build, some work was done to create a standalone libusrp which can
|
|
be nowadays found as a separate git repository together with other osmocom git
|
|
repositories, in https://git.osmocom.org/libusrp/
|
|
|
|
Related code can be found in the _Transceiver52M/device/usrp1/_ directory in
|
|
_osmo-trx.git_.
