Hi Andreas,
- layer23
doesn't currently filter much the IMM.ASS it receives so
you may end up on a channel that's not yours ... beware.
what do you mean with "much"? i filter the channel with the channel
request number (includes random number) in the IMM.ASS message. maybe in
the future we can filter the time slot where it was sent (RACH confirm)
and compare it also. but this requires RACH confirm with GSM time where
it was sent.
I was refering to "layer23" the quick & dirty test app if you want to
play with the layer1.
The mobile app does everything properly.
For the RACH_CONF, from the code, I see that it already contains the
frame number at which the RACH was sent.
(in the l1ctl_info_dl header of the CONF message, the frame_nr field is set)
