Prior to this patch, osmo-trx relied totally on proper VTY configuration being set in "rssi-offset" together with the RxGain set through TRXC in order to provide correct Uplink RSSI measurements to bts-trx. With this patch, RSSI is now by default calculated (in LMS and UHD backends) based on the currently set RxGain, by providing empirically discovered values. Still, for backward compatibility, the old "rssi-offset" command will overwrite completely the per-default calculated rssi offset. A new optional parameter "relative" is added at the end of the "rssi-offset" VTY command to flag the value as relative to the newly per-default calculated value. This way specific setups (like adding a LNA / RF fronted) can still be expressed while still keeping the automatic per-default offset.

About OsmTRX
OsmoTRX is a software-defined radio transceiver that implements the Layer 1 physical layer of a BTS comprising the following 3GPP specifications:
- TS 05.01 "Physical layer on the radio path"
- TS 05.02 "Multiplexing and Multiple Access on the Radio Path"
- TS 05.04 "Modulation"
- TS 05.10 "Radio subsystem synchronization"
OsmoTRX is based on the transceiver code from the OpenBTS project, but setup to operate independently with the purpose of using with non-OpenBTS software and projects, while still maintaining backwards compatibility with OpenBTS when possible. Currently there are numerous features contained in OsmoTRX that extend the functionality of the OpenBTS transceiver. These features include enhanced support for various embedded platforms - notably ARM - and dual channel diversity support for the Fairwaves umtrx.
