Hi all,
just to explain what i mean, i've attached a sample and the log from layer23.

As you can see from the log i got the immediate-assign. and the i can see the slots.
The only thing that i could be strange is the signal strength that sometimes is good and
sometimes reaches -100 dBm.
Here is the gprsdecode's output:

Obviously i tried other ARFCNs of all operators (with different c118/c123, FTDI cable) and
i got always the same behaviour.
Have you some hints to suggest?
Tomorrow i will try with some DP-L10 and pubblish the relative results.
P.S: As i already stated, Nohl's samples are well decoded and showed into wireshark.
Regards,
Luca
Hi Harald,
Actually i could use some old phones that supports only GPRS (e.g. t68i, t39m, etc..),
but these phones are not enough useful and i will explain why:
- i would like to use a phone that has field-test engineering;
- i would like to set the phone to camp only in a fixed ARFCN.
I was also trying a Pirelli DP-L10, but unfortunately i can only fix the band and not the
arfcn.
Btw... after a while i finally found how to force my Blackberry to work on GPRS on a
fixed arfcn:
- Select an arfcn;
- Lock to this cell; [

- Disable Uplink 8-PSK; [

Finally the phone is ready to start the tests. [

As you can see, that engineering field-test is very useful because is showing which
Coding Scheme and TS are used.
Unfortunately at this point... even if i tried a lot of times, i could see imm-ass, the
TS, but when i'm trying to decode the dumps... nothing is decoded and i cannot even
decode third-party sessions that obviously i could find on the same arfcn that i'm
using.
So, at this state of art, I could decode only samples released from Nohl.
Someone else is having same problems?
Regards,
Luca
