Phone doesn't auto connect to yatebts

desma:
Hello, I am trying to make a working bts with yate, but phones won't connect automatically, and if I try to manual connect to my network it takes long time and in the end it says network not available..also the command in telnet nipc list registered is empty..but nipc list rejected also is empty.
The carrier stays up and fine at my downlink frequency until i issue the stop command, checked using gqrx with another antenna.
I am using the bladerfxA4 and followed these instructions for installation https://nuand.com/forums/viewtopic.php?f=5&t=5094#p9358
my system is Lubuntu 18.04 on an intel i3 4 cores pc.
these are the bladerf info:

My ybts config is here: http://cauldron.altervista.org/ybts.conf
And here the log: http://cauldron.altervista.org/yate.log6

Does anyone can help here? I've also bought a bladerfx40 and I'm having the same result. Any tips? Nuand forum is locked to new questions so I'm forced to ask here. Thanks in advance.

Hi Desma,

To help debug this you can use the telnet console: telnet 0 5037
To clean the logs: debug gsmtrx off. That information is not relevant  and it usually flods the logs.
Then activate better logging: debug ybts level 10, debug mbts level 9. This should show if you actually see the registration requests.

Regarding automatic registration:
- if the MCC MNC on the SIM are different than the ones configured, the phone won't try to connect automatically
- if registration was rejected (depending on the error message) the phone won't try again , you can try to remove the sim and insert in back again. But some phones might not try again. You should use a different phone/sim.
- where is the subscriber information stored: subscribers in nipc mode/ regexp/ roaming mode to a core network?

If you suspect a radio issue:

Hi Monica, thank you for your kind help, the fact is that I'm working on an emergency bts, needed in such situations (disasters, earthquakes) where normal mobile operators are not available..so all the phones in my range must connect to my bts. Is it possible?
I tried your commands..but should I start yate with:
--- Code: ---sudo yate -vvvvv
--- End code ---
and then set the log levels in telnet right? Because I can't see that much. does the log levels must coincide with the number of -vvvvv when I start yate?
