fixeria has uploaded this change for review. ( https://gerrit.osmocom.org/c/osmo-bts/+/32285 ) Change subject: osmo-bts-virtual: properly activate [CBCH/]BCCH/CCCH ...................................................................... osmo-bts-virtual: properly activate [CBCH/]BCCH/CCCH In change 8e04613e I overlooked that osmo-bts-virtual is re-using the scheduler of osmo-bts-trx and forgot to update its OML logic. As a result, osmo-bts-virtual is broken and does not transmit anything on the broadcast channels.
