What does it mean "link is builded"?

Postby akouz » Tue Aug 30, 2016 7:48 am

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?

Hi Sir:
for AT+CIPMUX, something need your notification:
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 fellow the steps and still meet the problem, please list the reproduce steps for my verification

Thank you. I am aware of that because it is described in the AT+CIPMUX command description.

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.

“link is builded ERROR” that means ESP 8266 is under the connection. before you use "AT+CIPMUX=1", we recommad you disbale the ESP8266 connections
