</div><pre style="font-family: monospace,monospace; white-space: pre-wrap;">fake_trx: introduce CTRL commands for RSSI simulation<br><br>Since FakeTRX is a proxy, it basically emulates transceiver for<br>both osmo-bts-trx and trxcon, hence there are two separate and<br>independent control interfaces (usually, ports 6701 and 5701).<br><br>All simulation commands (see 'FAKE_*') are usually implemented<br>on both interfaces separately:<br><br> - ctrl_if_bb.py - simulation commands affecting Uplink,<br> - ctrl_if_bts.py - simulation commands affecting Downlink.<br><br>This change introduces the 'FAKE_RSSI' command for both CTRL<br>interfaces in two variations:<br><br> - absolute: CMD FAKE_RSSI <BASE> <THRESH><br> - relative: CMD FAKE_RSSI <+-BASE_DELTA><br><br>where 'THRESH' affects optional value randomization.<br><br>Change-Id: Ic01c31fb0304345dd7337c3ee1c7ee3c2d3e8460<br>---<br>M src/target/trx_toolkit/ctrl_if_bb.py<br>M src/target/trx_toolkit/ctrl_if_bts.py<br>2 files changed, 42 insertions(+), 0 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace;
