I am using BC66NB module. The communication to our server is OK. But sometimes I have a problem with receiving data from our server. Sometimes the data is in the module in few seconds, sometimes it takes several minutes (ca. 5 min.) and sometimes the data doesn’t receive at all (I have to send data to the server and then I receive the data).
I have tried to disable all sleep modes (AT+QSCLK=0, AT+CPSMS=0,“11100000”,“11100000”), but it didn’t help.
We are using UDP protocol.
Probably the problem isn’t on our server.
Thank you very much for your help.
