It´s my first post and probably as the most of you, here a I am after spending too much time trying to solve such a mysterious problem. Indeed, a lot of problems have already been found and solved after many, many hard days, but now I have something really tough:
I can´t get a refreshed page on a ESP8266 set as a server (AT+CWMODE=3, AT+CIPSERVER=1,80) and to accept multiple connections (AT+CIPMUX=1).

I can have the page loaded and exhibited by the browser, but only once. After AT+CIPCLOSE=<id> command as a result of finishing page load on browser, any AT command after that doesn´t work and a "busy p..." message is showed. Only a reset to make it operative again.

I could not find any clue on dozens of ESP8266-related pages I´ve found and now I have no idea what is causing that. Too many days have been spent reading documentation and experimenting all sort of things.

Any clue?

I have the same problem... I believe it is a bug in the 0.21 firmware.

I found the following which seems to be the answer... http://bbs.espressif.com/viewtopic.php?f=13&t=163#p632

Haven't tried yet but will later today.

Cheers

The ESP05 has GPIO0 pin permanently connected to VCC. Needs to be connected to GND for flashing... which means cutting a tiny PCB trace and connecting to GND. It looks hard... but I might give this a go later in the week.

I tried using the AT+CIUPDATE cloud update.. this seems to go through all 4 steps... but then gets an error.. and no update is done. So I think manual flashing is the only way to go to get to v0.22

Version of my ESP-01 is 0.21...

I´m expecting arrival of ESB-serial adapter I´ve ordered last friday. It seems that it will be delivered tomorrow
As soon this adapter arrives, I´ll try to update my esp8266 and I´ll post results.

Regards
