Re: Bug in WPA2 EAP
The problem was not resolved for one year. It is pity. But at least SiLabs offer modules capable to handle WPA2 Enterprise.

Does CH_PD pin do the same as the Deep Sleep command?
SDK function system_deep_sleep puts ESP8266 into Deep Sleep mode. Chip will wake up after reset pulse on the RST pin. But what is CH_PD pin functionality? Simetimes that pin marked as CH_EN too. When I pull CH_PD low current consumption is reduced to the deep sleep level. But when I release it, does...

My steps for your reference, "AT+CIPMUX" works ok
I use the same steps, initially it was OK too. Then I added more AT+CIPMUX=1 commands. Most of them are OK, but sometimes I see "link is builded ERROR" reply.

Re: Cannot connect to ESP8266 after a while
please highlight which router to reproduce the issue. We used Billion BiPAC 7300G We also tried Billion BiPAC 7800N. That router keeps disconnecting ESP8266 from WiFi every 5 minutes. However the module works with a Netis router without any problem fol long time. Also it works well with a pocket Wi...

Re: What does it mean "link is builded"?
1. "AT+CIPMUX=1" can only be set when transparent transmission disabled( "AT+CIPMODE=0") 2. This mode can only be changed after all connections are disconnected. 3. If TCP server is started, has to delete TCP server first, then change to single connection is allowed. if you done...

Re: Cannot connect to ESP8266 after a while
The problem could be caused by our access point. We test it with other access points. In some cases it works OK for long time.

What does it mean "link is builded"?
AT version:1.3.0.0(Jul 14 2016 18:54:01)
SDK version:2.0.0(656edbf)
compile time:Jul 19 2016 18:43:55
Occasionally I get the following response to AT+CIPMUX=1 command:
AT+CIPMUX=1
link is builded
ERROR
This response is not described in documentation. What does it mean?

Re: Cannot connect to ESP8266 after a while
I downloaded the latest SDK 2.0 and programmed the "noobot" AT code for 512K. Good news : this version does not crash on the "connect - send 3 bytes - disconnect" sequence. Bad news : this version still refuses to make TCP connections to some computers after about one hour, at ra...

Re: Cannot connect to ESP8266 after a while
While waiting for modules with bigger flash where I can fit the latest AT commands, I keep testing the code with AT rev 0.60. Sometimes the following messages appear at ESP8266 output without any visible reason: WIFI DISCONNECT WIFI CONNECTED WIFI GOT IP After that connection to network is lost, and...

Re: Flow control and AT protocol
Are you sure that UARTS stores characters in an internal HW FIFO ? Do you think that the UART in the ATMEGA328 has such a buffer ? Do you know which length it is ? I carefully read the ATMEGA datasheet and never saw anything about this. RTFM. ATMEGA328 datasheet , clause 20.11.1 UDRn – USART I/O Da...
