Hi list,
I recently built the testing branch and openbts with respect to the transceiver-app.
I built openbts without compilation flags for uhd and resamp(saw on irc that that
should'nt be required)
and without gnuradio.And I use the example sql openbts.db. I then use rssi-app to find the
strongest reference cell and modify openbts.db
But when I upload the firmware Lost messages occur after a series of stale
burst-messages.
openbts outputs a long chain of <0011> trx.c:512 TRX DATA .....
interupted by single <0011> trx.c:190 TRX CLK Indication-messages.
And phones of cannot register to openbts-network or even see it when doing manual scan.
Can the timing advance parameter and the BSIC parameterbe inserted to the openbts.db to
remedy the failure of sync of the osmocom-phone-bts? If not can other measures be taken?
regards
erich
