Problem with satellite fixation l86-m33

I have a rather strange problem, my l86 sometimes desperately cannot catch more than 1 satellite, it doesn’t even see them, which is strange, it doesn’t depend on the location, the receiver is located in a good place. This is how the module has been responding to me for the past 15 minutes.

This problem is not constant, often the module is able to catch quite quicklyundefined satellites, sometimes throughout the day he can’t even see them, I don’t know what to do, please give me advice on where to go. undefined.

Before starting I send these pmtk commands to the module

PMTK286,1
PMTK353,1,0,0,0,0
PMTK311,10

Hi @ilya
From the log, it seems that the module cannot search for satellites well because the L86 module antenna is in the “OPEN” state. Please check the antenna connection status. When the antenna status is “OK”, test again to verify.
