Found it, its TS 102 497. I've implemented what I think is necessary
to work with US-DECT in the 1920-1930 MHz band. The other bands are
not supported by the Com-on-Air transceivers. Please back out your
band-setting changes and try the attached patch.
I've enabled debugging output in the patch. Please send me the
resulting log, whether it works or not, I can't test this myself.
Thanks.
The driver seems to work but the issue is that I
am trying to use it in USA
for an American client, and I did not managed to make this card use the
1.9Mhz band (rf band 3 I guess).
When I run this command:
dect-transceiver-list --name trx2 I see that slot0 is scanning:
DECT Transceiver trx2@cell0:
Type: sc1442x
Features: slow-hopping,p64
RF-band: 00003
Events: busy: 0 late: 0
slot 0: <scanning> packet: P00 carrier: 5 (1888.704 MHz)
RX: bytes 0 packets 0 a-crc-errors 1629 x-crc-errors 0
z-crc-errors 0
but it nevers uses RF band 3 channel.
For you information I have patch the driver this way to set the default
debt rf band to 3:
Your patch looks fine. The problem is most likely that in all bands carriers
0-9 use the same frequency, so I'm guessting that US-DECT
uses different carrier numbers. I wasn't able to find anything related
to that in the base specification. If you can find a document defining
the exact operation of US-DECT, I can modify the stack in order to
properly support it.
