I'll go ahead and recompile openBTS using your version. Thank you!
That worked out rather smoothly. I can see the '00101' GSM network on my phone and OpenBTS attempts to SIP REGISTER when I choose it on the phone.
Here are my notes, I'll be posting further updates there as well: http://blog.shimaore.net/2013/02/umtrx.html Hope this helps.
Next steps for me are to setup FreeSwitch (and maybe OpenSIPS) so that I can start testing calls.
Question: I used RX1 and TX1 on the board to connect the antennae, but `transceiver` says "using transmit antenna RX1" and "using receive antenna TX2", does that mean I should use RX1/TX2 instead, or is this a configuration parameter I should modify in OpenBTS.db?
S.
PS: Congratulations to everyone involved in making this so painless! Eight hours (lunch included) from unpacking to being able to see the MNC show up on a phone is _very_ nice.
