Sorry for the inconvenience :oops:

00170901 is a very very old version of AT，it may have many defects..

please try the latest AT_v0.22 http://bbs.espressif.com/viewtopic.php?f=7&t=205

There should not be any "OK" after +IPD

my memory is may be faulty, but i'm pretty sure than older AT firmware ended with an "OK" after a dual \CR\LF !
(i works with multiple connection enable)

will verify with previous firmware !

regards

edit ********************************
i upload the old 00170901 and YES, the "OK" is send after the HTML header and dual \CR\LF (which is part of the HTML header) !

no more with the 022b1 ...

thanks to Espressif team to modify without say nothing ...

AT Command manual in verion: http://bbs.espressif.com/viewtopic.php?f=5&t=154
esp_iot_sdk_v0.9.5_15_01_23.zip\esp_iot_sdk_v0.9.5\document\English folder

Not retrun 'OK' and at least I don't see reason for that because received data can include also 'OK'

From AT document:
NOTE:
When the module receives network data, it will send the data through the serial port using +IPD command
Param description：
<id> id no. of connection
<len> data length
<data> data received
