Hello, I try to use the 'host23/mobile' application on a C123 but without success. I followed Steve's instructions[1] with today's git tree (d95eddad): 1. osmocon -p /dev/ttyS0 -m c123xor layer1.compalram.bin 2. ./host/layer23/src/mobile/mobile 3. Power on the phone (output of theses commands is thereafter) But I'm not sure it really works: the firmware seems to freeze (not responding to the power button anymore) and the last output of 'mobile' is: <0003> gsm322.c:257 Sync to ARFCN=104 rxlev=-65 (No sysinfo yet, ccch mode NONE) Based on the low rxlevel, I guess it is not acquiring any meaningful signal? In [2], Steve said the internal antenna was switched off when the cable is plugged in, is it still true? I tried to RTFM but I am stuck here.

Based on the low rxlevel, I guess it is not acquiring any meaningful signal?
-65 dBm is a pretty strong signal actually :) It should be able to sync down to -105 dBm or so.
In [2], Steve said the internal antenna was switched off when the cable is plugged in, is it still true?
It's true and won't ever change ... it's a hardware switch, when you plug something in the antenna plug, it disconnects the built-in antenna.

It's weird that the power varies so much ... it's also weird that it even _tried_ to sync with a 22kHz frequency error .. It might try to sync to something that's not a C0 ... Try to force the ARFCN to a known good cell (that you get from a phone with netmonitor) using the stick option. Cheers, Sylvain

Hi, you have not forumalated a question that can be answered in a very specific way? You seem to have an expectation that the invocation of tools is doing something, but they don't do what you think they should do. Maybe as a start you should describe what you expect should happen and what happens instead? Maybe people can then help you more.
sorry, my question is, what is with the dropped frames in my submited output of layer23 is that ok? or not? and if not what must i do? -- View this message in context: http://baseband-devel.722152.n3.nabble.com/Newbie-C123-layer1-compalram-bin-...

layer23 is a debug tool that can only really be used on a network you control, because it will follow any immediate assignement without any further check (refer to GSM 04.08 if you don't understand what that means) On a commercial network, it won't do anything good. The output you see is normal if you run it on a real network and not a test network you control. Cheers, Sylvain
Hi, sorry i misunderstand layer23, i am searching for a possibility to log my traffic on the um interface, to check out if my real phone traffic is encrypted and to what bts i am connected(is it the real network or a catcher). PS: all that, i want to do it on a real network. -- View this message in context: http://baseband-devel.722152.n3.nabble.com/Newbie-C123-layer1-compalram-bin-...
