AT+CIPSTART bug when using UDP and DNS lookup

[trickedj]

Hi Espressif team, well done for a great product

I hope this is the correct place to post but I have found a debug in the AT command implementation.
I am using at_v0.20_14_11_28 to contact a NTP server via UDP. If I use the IP address it works ok as below

AT+CIPMUX=0
AT+CIPSTART="UDP","134.130.4.17",123
AT+CIPSEND=48
NTP Recieved OK

However if I use a domain name, the DNS lookup works correctly but the following AT+CIPSEND hangs with no > data prompt

AT+CIPMUX=0
AT+CIPSTART="UDP","pool.ntp.org",123
AT+CIPSTATUS returns +CIPSTATUS:0,"UDP","217.114.59.3",123,25349,0
AT+CIPSEND=48 - hangs with no > data prompt

I have looked at the source code for AT+CIPSTART in 'at_ipCmd.c' and i see that for a UDP start with IP address
espconn_create is called at line 818 (TCP calls espconn_connect). However if a DNS lookup is required, the callback function
at_dns_found calls espconn_connect for both TCP and UDP !

I think at_dns_found should call espconn_create for UDP ?

Also at line 731 "ALREAY CONNECT\r\n" should be "ALREADY CONNECT\r\n" or even better english is "ALREADY CONNECTED\r\n"

I hope you can correct this problem. If you like to post new user.bin file I can test it out

Thankyou
