Hi!
I´ve got a Nano serially connected to an ESP9266, when I try to send a short string to an UDP server running in an Android phone (connected to the wifi net provided by the esp, for sure), after I send the
AT+CIPSTART=4,"UDP", "192.168.101.110", 3000, 1112, 0
to the module it answers
4 CONNECT
OK
But when I try to send the data using
AT+CIPSEND=4, 5
It answers "no tail" and there´s no transmission.
Anybody knows what "no tail" means?? Google says nothing useful.
Thanx!!

Solution found!
There´s a mistake (very subtle typo) in the datasheets v1.3 that I was using. It´s one character misplaced. Erased it, and now it´s working as expected.
