PREAMBLE PQI check not working on STM32WL33xx

syn
Visitor

Hi, I'm searching for the best  Rx sniff mode as suggested in AN6362: I'm able to use carrier sense (RSSI_THR, CS_F interrupt) and SQI (SQI_THR, SYNC_VALID_F interrupt) but PQI never works.

The MCU is in WFI state, sequencer not used.

I have changed the value of  PQI_THR but PQI_INFO is always zero and the PREAMBLE_VALID_F interrupt is always received a few microseconds after CS_F interrupt.

Thank you in advance!
