Re: [Openbts-discuss] Running OpenBTS with GPSDO as external

[Neel P. <nee...@et...>]

Hello Simon Pålstam:

Also note that in UHD 3.9.x, the selection of the GPSDO as the timing and
clocking source is no longer automatic, and must be made explicitly. I
don't remember if the TransceiverUHD and OsmoTRX transceiver processes
already include code for doing this. Which version of UHD are you using?
Which transceiver are you using, and which version?

+*Tom* *Tsou*: Could you please comment further on this? Thanks in advance
for your help.
