Hello,
I have loaded the new AT bin to my application. And it seems, that what was working before with the AT v. 20 doesn't work now. Can you help? In fact, I have TCP server mode and I am receiving HTTP requests. Seems, that first connection is OK, but when I close the first TCP, I am not able to use the module at all and just receiving BUSY. Please note, that this code fully worked without any single change for all the previous AT releases. Here are the AT commands flow:

SDK0.9.5 + AT 0.21 bug, when using server with multiple conn
Re: SDK0.9.5 + AT 0.21 bug, when using server with multiple
hi, i notice the same problem here !
after the first reply to a GET request, the ESP8266 seem "halted" .. the reply is always "busy p..."
with the previous AT firmware (0.20) it was working "better" (unstable with unsolicited message sometime, but not hanged !)
i'm really disappointed with this ...
plane to change my mind and use another chip until a working & stable AT firmware is provided !
regards

Hello, great, it seems that this is now working great! Even now the, when the static IP address is saved in the flash, the woke up and connect from power down is very fast. I am only little bit sad, that the AT firmware is not open source any more. I understand probably your point, that then you will have troubles to support customers, who will not have your original fw, however there cannot be a simple AT command to do e.g. the checksum of the user flash to know, if original fw is there or not?
Are there any plans to e.g. support the webserver in the AT fw? Or at least to e.g. read / write the module flash memory to be able to store there e.g. the webpages?
