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:

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…

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.
