Receive sensitivity of GFSK modem on STM32WL55

The STM32WL5x Datasheet mentions the RX Sensitivity of the Radio Modem for both 2-FSK and LoRa modulation (see image below) but makes no mention of GFSK, GMSK or BPSK

What are the receive sensitivity values for these modulation schemes?

Hello @MoralkaraLynn and welcome to the ST Community :smiling_face_with_smiling_eyes:.

The sub-GHz radio implemented on the STM32WL5x support Transmission and Reception using the LoRa and the 2-FSK modulations. But it supports only the Transmission for the 2-MSK and BPSK modulation. So, no reception for GMSK, MSK and BPSK. For the GFSK, it is mentioned on the 2-FSK (FSK & GFSK). 

Then, RX sensitivity parameter should be available only For LoRa, FSK and GFSK.

Best Regards.
