[Ubertooth-general] UAP recovery with ubertooth-rx

[Joshua W. <jw...@ha...>]

I'm reacquainting myself with the revisions to the Ubertooth tools.  Where
previously ubertooth-nap was used to recover the NAP, I believe
ubertooth-rx does that job now.

However, I can't seem to find the correct syntax to perform UAP recovery:

root@astatine:~# ubertooth-rx
systime=1391392019 ch=39 LAP=a656f7 err=0 clk100ns=791221159 clk1=650883
s=-48 n=-90 snr=42
systime=1391392019 ch=39 LAP=a656f7 err=2 clk100ns=794145353 clk1=651351
s=-47 n=-90 snr=43
systime=1391392019 ch=39 LAP=a656f7 err=0 clk100ns=797102326 clk1=651824
s=-48 n=-90 snr=42
systime=1391392021 ch=39 LAP=a656f7 err=0 clk100ns=813295872 clk1=654415
s=-47 n=-91 snr=44
systime=1391392021 ch=39 LAP=a656f7 err=2 clk100ns=815084164 clk1=654701

systime=1391392022 ch=39 LAP=a656f7 err=2 clk100ns=818785158 clk1=655293

^Croot@astatine:~# ubertooth-rx -h
ubertooth-rx - passive Bluetooth discovery/decode
Usage:
    -h this help
    -i filename
    -l <LAP> to decode (6 hex), otherwise sniff all LAPs
    -u <UAP> to decode (2 hex), otherwise try to calculate (requires LAP)
    -U <0-7> set ubertooth device to use
    -c<filename> capture packets to PCAP file
    -d<filename> dump packets to binary file
    -e max_ac_errors (default: 2, range: 0-4)
    -s reset channel scanning

If an input file is not specified, an Ubertooth device is used for live
capture.

Knowing the LAP, and seeing the "-u" argument "otherwise try to calculate"
I thought the UAP recovery would involve specifying the LAP and an empty
-u, but that returns an error:

root@astatine:~# ubertooth-rx -l a656f7 -u
ubertooth-rx: option requires an argument -- 'u'

What is the right way to recovery the UAP?  I am using the git sources and
current git firmware.  Thanks!
