Hi Tom,
Can you please elaborate a little "how can i drive the seperate RF paths as
two TRX units controlled by one osmobts instance?"
i have tried setting the configuration file for osmobts-trx (osmo-bts.cfg)
by adding 'trx 1' section at the end, but i got an error when starting
osmobts. i was not able to find any documentation regarding this setup.
further fairwaves umtrx hardware supports 2 seperate RF paths, does that
mean that i can use fairwaves umtrx hardware with single osmo-trx and single
osmobts instance?
thanks,
Arif

Or maybe there is already a saner method i could not figure
Right now you can only drive the separate RF paths as two TRX units
controlled by one osmobts instance. Communicating with each TRX
independently with multiple osmobts instances is not supported. The
reason for this is that are some operations (e.g. thread setup) that
are tied to TRX0 with the expectation of a single C0 setup rather than
completely independent configuration of channels.
