ERROR after a few AT+CIPSTART... requests

Question

Hi, after a few (about 35) “AT+CIPSTART="SSL","www.google.com",443
” requests I get “ERROR” response from module. Before that I set: “AT+CIPMUX=0
” “>OK” “AT+CIPSSLSIZE=4096
” “>OK” Does anyone has idea what is going on? Best, Mateusz

Hello @msemegen Did you connect to Wi-Fi before using ‘AT+CIPSTART=“SSL”,“www.google.com”,443’ command? image1050×802 84.9 KB

Yes, I’m connected. I reproduced Yours settings and situation is the same. First connection is successful but after some time (connecting and disconnecting with google.com with 500ms delay) I’m starting to receive “ERROR” response. As I can see, I have pretty old module FW: “AT version:1.0.2.5(Aug 23 2019 17:03:59) SDK version:3.2.0(a0ffff9f) compile time:Aug 23 2019 17:00”
