Connection resent when sending large files?
Posted: Mon May 30, 2016 1:10 amPosting in both General Discussion and ESP8266 Arduino->General Discussion for exposure
All my code can be found at https://www.dropbox.com/sh/neu1nk9hfg0pd64/AABGROLkb7dTM54115x45aK1a?dl=0
I'm currently working on an ESP webserver platform that can serve large mostly-static webpages saved to the ESP's flash memory at compile time. I've been working with the FLASH library and conversion script setup discussed here:http://www.esp8266.com/viewtopic.php?f=32&t=3780
The code I linked in the beginning (with the edited ESP8266WebServer library) works fine for small webpages (the one's I've tested are all under 5kb in size). Then I moved to a larger webpage (the one that is currently in the server/website folder) all my code compiles correctly, however when I try to serve a page that large, while the ESP is sending its response the connection is reset, presumably due to the large size since it did not occur with smaller pages. I figured that this was perahaps due to the fact that the client.write() line within the loadFromFlash() method is limited by the HTTP_DOWNLOAD_UNIT_SIZE buffer length, but all other methods of sending the data such as server.sendContent_P() and server.send() have only given me corrupted data on the clientside.
Any suggestions for improving this code would be greatly appreciated! Thanks in advance.
