CC3200: RSSI sudden drop

Part Number: CC3200

Greetings,

I am working on a CC3200 MCU and I am facing a problem which origins remain unclear. My device's RSSi is usually between -58 and -36, but sometimes and for no apparent reason it suddenly drops to -99 then goes back up in less than a second.

Could you please tell me more about the possible reasons for this problem?

My most sincere thanks in advance.
