Hi,
after a few (about 35) “AT+CIPSTART="SSL","www.google.com",443\r\n” requests I get “ERROR” response from module.
Before that I set:
“AT+CIPMUX=0\r\n”
“>OK”
“AT+CIPSSLSIZE=4096\r\n”
“>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?
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”
Ok,
updating FW to latest version, probably fixed the problem!
Best,
Mateusz
