FC41D - WiFi RSSI value convertion

Hello everyone, I’m new to this forum so nice to meet you.

I’m currently working on a device which integrates FC41D module, and I’m using AT+QWSCAN command for FC41D for getting hotspots info.

As per last AT Commands manual I have (2022-09-27), the corresponding command has this response:
+QWSCAN: ,<PSK_type>,,,

where is described only as: Integer type. Wi-Fi signal strength.

From my tests it seems to use the 0-63 range (where 63 is maximum strength) but I haven’t found confirmation anywhere, nor I found the corresponding formula to convert it into dBm negative value.

Any help is appreciated, thank you in advance.

Sorry let me resend the info about the AT command:

We processed the RSSI value returned by the AT+QWSCAN command
Scan return value (positive value) = actual value (negative value) + 100

Range: 0~receiver sensitivity
