YateBTS / Re: Can't detect my GSM network with newest phones.
« Last post by kycfeel on December 11, 2017, 04:57:38 AM »
Hello. Thanks for the reply.

I live in South Korea, My test network is using 900 band with 001 MCC 01 MNC (Test Network), and my BladeRF is calibrated with factory settings.

Trying to use 1800 band instead of 900, or Reset iPhone's network settings doesn't helped me. Still can't figure out what is the problem.

Anything that i can try more?

It is important to know the following:
- Is the bladeRF frequency (auto)calibrated?
- Are you using the 850MHz band?
- What is the PLMN (MCC+MNC) of the IMSI
- What is the PLMN broadcasted by the BTS
- Where you are located geographically

At the whim of US operators Apple (and others) have introduced restrictions about which bands are available to which networks. In some conditions the phones may not list some or all cells in a band. This depend on the hardware version, iOs version, SIM and network identity. I am not sure but it's possible that geolocation may be taken into account as well.

The GSM850 / LTE band 5 is one of the bands affected since it's supposed to be used only in North America, South Korea, China and Australia. If you're located somewhere else or not having a matching IMSI the phone may not list cells or may behave erratically.

Try using one of the worldwide GSM bands - 900 or 1800. These are unlikely to be restricted.

YateBTS / Can't detect my GSM network with newest phones.
« Last post by kycfeel on December 04, 2017, 04:27:14 AM »
Hey guys.
I'm testing my Yate 6 based GSM network built with Raspberry pi and BladeRF x40.
and I think i can't detect my network with newest phones (iPhone 6s or higher).

My old iPhone 6, 5c, and Motorola MB860 can detect it, and connect to it very well.
But newest phones, like iPhone 6s, and iPhone 7 can't even detect my network on settings.
I'm not sure about newest Android phones cause i don't have any test devices right now.

I'm pretty sure that every iPhones released to market support GSM network connectivity. So definitely not the hardware problem.
Any of you experiencing same problem as mine? Need your help!

The timestamp jumps usually mean that the CPU is not keeping up with the radio signal. If they are not too severe, YateBTS will still work. If your phone sees the beacon, then it might be OK. You say "a lot" of timestamp jumps? How often do they happen?

Linux / Re: embedding Yateclient with rmanager controls
« Last post by marian on November 29, 2017, 02:36:10 AM »
I suppose you are routing incoming calls to an audio device module (alsachan).
You may add an autoanswer=no parameter when routing the call.

You need some logic to anwer calls on demand.
You may write a javascript script to track calls (you may use call.cdr for that, 'chan' parameter is what you need.
The script should implement a command to answer (just send a chan.masquerade message with call,answered) a specific channel id.

Linux / embedding Yateclient with rmanager controls
« Last post by brad on November 28, 2017, 10:01:26 PM »
I'm embedding yateclient in a small Linux headless machine.  I can use rmanager via telnet to initiate calls (using call) and status cdrbuild to watch for incoming calls.  I'd prefer to not 'auto answer' inbound calls, rather, I'd like to be able to control when and if the call is answered via rmanager.   

Is there a parameter that I can set via the rmanager interface to change the current cdr status from 'ringing' to 'answered'?

Hello Jambo,

Please try from rmanager (telnet 0 5037) to set 'debug ybts level 9'
It will give you information about the subscriber that wants to attach to the BTS. (There you will have an <imsi> </imsi> field containing the IMSI)

YateBTS / Re: Difference of the USIMS
« Last post by afk on November 28, 2017, 03:28:24 AM »
Hello smlee,

Can you please provide us the username of your HostedCore account?

Regarding the USIMs difference, there should not be one. All SIMs are from same batch, but we will look into it after we recognize your order/product.

Thank you in advance
