LLCC68 CAD randomly wake up issue

Semtech Transceivers SX126x family
#1

Hello,

We have problem with SX1262/LLCC68 cad wake up issue.
It seems like cad detection will randomly detect even there’s no LoRa signal in the air. (we testify in Anechoic Chamber)
that will cause problem if we use application note “SX126x CAD Performance Evaluation” tuning CAD&PER, there will a extra cad detection we don’t want, and cause more current consumption. Is it helpful by changing different value of cadDetMin (rather than recommend value 10) or other register value ?

It would be great if someone from Semtech could look into this…
