Explanation of prints chg_B1:0 chg_B1:-40...

Hi Experts,

We have several units deployed based on ESP-12E and on some of the units we are missing broadcast packets. The only difference that we observe on console is following prints. These prints appears continuously on console for the units where we see the problem. These prints are not observed on the units where all the packets are received perfectly.

Can espressif team please let us know the meaning of these prints as they are from library and give some ideas why they are only observed on certain chips and not on others while hardware and PCB is exactly same and both units are connected to same router from same distance.
