Vadim Yanitskiy gerrit-no-reply at lists.osmocom.orgHello Harald Welte, Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/6846 to look at the new patch set (#3). fake_trx/ctrl_if_bb.py: add FAKE_RSSI and FAKE_TOA commands At the moment, the BurstForwarder performs simple randomization of both RSSI and ToA values for each forwarded message. Let's add two additional CTRL commands, which may be used to manually update the mentioned message fields. This is useful for testing the measurement processing code in OsmoBTS.
