Ok, thanks to all of you for your helpful answers.
So, I've tried to use a SIM card I already have (from SFR), but
unfortunately, I can't get my phone to register.
In OpenBTS.config, I've set:
- GSM.MCC 208 (France)
- GSM.MNC 01 (test) - I'm unsure whether I should use '10' here for SFR or
not to match my IMSI
- GSM.Band 1800 (that's what we use in France)
- GSM.ARFCN 880 - honestly, I'm not very sure about that param. I found that
in an online calculator (
- Control.OpenRegistration 1, with messages in each case to be able to debug
I suspect I also have an error at some other level, because my logs complain
about TX not tuning:
"driveControl: TX failed to tune"
"TXTUNE failed with status 1"
how do I fix that?
Apart from that, my USRP seems to be 'working'. I mean, I tried
usrp_benchmark_usb.py and got some benchmarks, I also tried
usrp_wfm_rcv_pll.py which seems ok around 1800M, I also tried
./usrp_siggen.py -T A -f 1800M which looks ok to me. Well at least, nothing
there is crashing or displaying an obvious error message ;)
Can you help me fix this?
