SSL Server only sends once and then throws error -5

[davydnorris]

I have added SSL capability to the esphttpd project, and everything seems to be working fine in regular HTTP mode, but when I connect a client via HTTPS, the espconn_secure_send() function will only work the first time. The next time it fails to send with error -5 (ESPCONN_INPROGRESS).

Checking the recv callback and the connection state shows that the connection is fine and is not in progress. I'm using the latest NonOS SDK 2.1.0

This post has had exactly the same problem: http://bbs.espressif.com/viewtopic.php?f=16&t=3423

This is a debug dump of the esphttpd server callbacks and functions as I first try https://<server>/ (which redirects to /index.tpl), and then I try https://<server>/wifi (which goes to /wifi/wifi.tpl).

Hi,

Can you provide the test code for debugging?

Thanks for your interest in ESP8266!
