NUCLEO STM32WL55JC1: Sensitivity seems low?

 Hi, 

I am prototyping a PINGPONG project on two NUCLEO STM32WL55JC1 with en.stm32cubewl-v1-3-0 software.
I am checking the link at low Rssi values driving one board apart from the other.
The parameters are below. I change OUTPUT POWER from 0 to 22dBm.

In all trials the receiver stops receiving packets when Rssi gets below -107 dBm.
This is far too early. LoRa should receive packets at lower Rssi values. What goes wrong ?
