Hi,

Please try

Code: Select all

AT+CIPSSLSIZE=4096
AT+CIPSTART=“SSL”,"iot.espressif.cn",8443


SSL connection needs a lot of memory, otherwise, it may cause system reboot.
Users can try command "AT+CIPSSLSIZE=<size>" to enlarge the buffer size.

We have updated the documentation http://bbs.espressif.com/viewtopic.php?f=51&t=1022, sorry for the inconvenience.

Hi,

I am still having this problem even with AT+CIPSSLSIZE=4096. I get the following:

Code: Select all

AT+CIPSSLSIZE=4096

OK
AT+CIPSTART="SSL","iot.espressif.cn",8443

I am using the 0.60 AT firmware from here with an ESP-01 module.

Can you help?

Hi,

What is the size of your flash, 512KB? 1024KB? Or other size?

Please download bin files into flash through ESP Flash Download Tool, the flash size will be shown on the "DETECTED INFO" are on the tool while downloading.

Hi.
I'm use esp8266 (8Mbit) and wroom-02 with host processor (AT commands).
I try ESP8266_NONOS_SDK_V1.5.2_16_01_29 and AT_V0.60_on_ESP8266_NONOS_SDK_V1.5.2_20160203 and they're works fine

So, pure SSL seems to working fine. Same results I get when communicate to servers with self-signed certs.
But we (customers ) need normal HTTPS to trusted! servers via AT commands!
Can we get this feature now if based on latest sdk release?
Can we get this featurein futher sdk release 'out of the box' ?

Hi,

Sorry that because of the memory limitation, AT firmware can not support to run as SSL server.

So sorry for the inconvenience.
