Communication between two ESP's

2016-10-14T02:05:31+08:00

I have been using two ESP's, one configured as an access point and the other configured as a client connected to the access point formerly created. I am able to send the data successfully but not receiving it on the client side. I have used direct AT commands for configuration and sending data. Following are the AT commands I sent in order mentioned at the access point:
AT+CWMODE=2
AT+CIPMUX=1
AT+CIPSERVER=1,333
AT+CIPSTART=,"UDP","ID of client",333
AT+CIPSEND=,no: of bytes

Every command gets executed properly as I receive "OK" and no errors and finally get a '>' prompt to type in my data (Using Serial Monitor on Arduino). After I give the data, I get the "SEND OK" reply! So, that's working fine!

On the client side, before I send data from AP, I connect it to the AP and get an IP. Following are the commands I execute in sequence:
AT+CWMODE=1
AT+CIPMUX=1
AT+CWJAP="ssid","password",, //overwriting the default set by the AP, in AP code first and then using the same here
AT+CIFSR //to check IP

Both are executing the "AT+PING" command well! Why am I then not getting the sent data on the client side? It should basically start with the "+IPD" string right? I use two ESP's with versions: 0.40.0.0 and 0.60.0.0! I hope that it is not a problem as both support the above used AT command set.

Thanking you in anticipation of your kind and earliest response in this regard.
Chetan.
