Hello Patrick,
I had a look at the net/dect/mac_csf.c file source code. dect_bc_si_cycle_complete() often returns false with "incomplete: SSI" kernel logs:

Its basically that chan_dect hasn't been converted to use the new API for wideband audio support yet. Just fixing this problem without actually adding wideband support should be relatively easy, I'll try to have a look during the weekend.

so how exactly was this test performed? I assume you used a real US-DECT FP and configured the cell to PP mode?
As far as I understand the code, in this case, the driver never locks, this would be the reason why dectmon never displays any message�
Correct, we need a full set of system information messages for locking.
The driver never logs any DBC message. This was the case before patching for US DECT. It seems there are EU DECT stations where I am testing this driver.

so how exactly was this test performed? I assume you used a real US-DECT FP and configured the cell to PP mode?
Yes, this was exactly the case:
dect-cluster-add --name cluster0 --emc 0x2284 --fpn 0x1af9d --mode PP dect-cell-add --name cell0 --cluster cluster0 --flags monitor dect-transceiver-bind --transceiver trx0 --cell cell0 dect-transceiver-bind --transceiver trx1 --cell cell0 dect-transceiver-bind --transceiver trx2 --cell cell0
then I run the dectmon tool..
As far as I understand the code, in this case, the driver never locks, this would be the reason why dectmon never displays any message…
Correct, we need a full set of system information messages for locking.
The driver never logs any DBC message. This was the case before patching for US DECT. It seems there are EU DECT stations where I am testing this driver.

so how exactly was this test performed? I assume you used a real US-DECT FP and configured the cell to PP mode?
Yes, this was exactly the case:
dect-cluster-add --name cluster0 --emc 0x2284 --fpn 0x1af9d --mode PP dect-cell-add --name cell0 --cluster cluster0 --flags monitor dect-transceiver-bind --transceiver trx0 --cell cell0 dect-transceiver-bind --transceiver trx1 --cell cell0 dect-transceiver-bind --transceiver trx2 --cell cell0
Please send me the full mac layer debugging output.
I will give you hex dumps of the concerned structures asap if you want… when I will have an access to the machine again…

Hello Patrick,
I had a look at the net/dect/mac_csf.c file source code. dect_bc_si_cycle_complete() often returns false with "incomplete: SSI" kernel logs:

so how exactly was this test performed? I assume you used a real US-DECT FP and configured the cell to PP mode?
As far as I understand the code, in this case, the driver never locks, this would be the reason why dectmon never displays any message…
Correct, we need a full set of system information messages for locking.
The driver never logs any DBC message. This was the case before patching for US DECT. It seems there are EU DECT stations where I am testing this driver.

... these are messages from FP mode. In PP mode you won't see them.
