- Sat Jan 24, 2015 7:02 pm #8124 Well I anxiously downloaded this new version and loaded it into an ESP-01 module. When I reset the module it only tx's the usual "trash" but then locked up. It never got "ready". I reflashed my module with the version I had been running, v0.9.4_14_12_19. I then attempted a "cloud" update with AT+CIUPDATE.
I saw the messages:
+CIPUPDATE:1
+CIPUPDATE:2
+CIPUPDATE:3
+CIPUPDATE:4

Then there was a pause of about 30 seconds, then the module rebooted. I then performed the cloud update to this version on two additional modules.

It worked flawlessly for me. I've been testing for about an hour and everything I've tried seems to work properly.

Give SDK 0.9.5. patch!

Yes... You got us .. Here is the patch http://bbs.espressif.com/viewtopic.php?f=5&t=154&p=557#p557

And RTC memory is 4Bytes as a count .. 64 means 64 X 4 =256 bytes..

Thanks for your interest in ESP8266 !

For users - the following 512 bytes for "system area" of 256 bytes.
