MM8108 noise suddenly raised, back to normal after a reboot

Hi community,

I have 2 MM8108 working in the mesh mode. While making a long observation, I saw that, the noise in one MM8108 (the right hand window) jumped and stayed stable from about -100dBm to -80dBm

It went back to -100dBm after a reboot

Please note that, there was no settings changes during the observation.

Is it something relating to AGC, LNA or so?

V.
