+IPD difference between UDP & TCP

2015-04-27T00:15:15+08:00

I have noticed in AT v23 that the +IPD responses are different between UDP & TCP.

In UDP the raw data is followed by an "OK" in TCP it is not. I've just updated from AT v20 and in that version both TCP & UDP issued an OK after the raw data. There was some discussion here viewtopic.php?f=16&t=221 about the removal of the (unneccessary) ok on TCP, but it appears to have been overlooked on UDP. It would be best for them to be both the same.

Thanks

An example follows:

AT+GMR

AT version:0.23.0.0(Apr 24 2015 21:11:01)
SDK version:1.0.1
compile time:Apr 24 2015 21:19:31

OK
AT+CIFSR

+CIFSR:STAIP,"192.168.1.84"
+CIFSR:STAMAC,"18:fe:34:9c:65:bd"

OK

AT+CIPSTART="UDP","192.168.1.71",100,100,0

0,CONNECT

OK

+IPD,8:incoming
OK <<<<<<<<<<<<<< Extra LF OK LF on UDP packet containing "incoming"

......
AT+CIPMUX=1

OK
AT+CIPSERVER=1,100

OK
0,CONNECT

+IPD,0,8:incoming0,CLOSED <<<<<<<<<<<<<< Nothing extra on TCP
0,CONNECT

+IPD,0,8:incoming1,CONNECT

+IPD,1,8:incoming0,CLOSED
0,CONNECT

+IPD,0,8:incoming1,CLOSED
0,CLOSED
