Using esp8266 wifi module


The AT + CWMODE and AT + CWJAP command normal execution


But the AT + CIPSTART="TCP", "169.45.3.132", 1883 when prompted the link is not valid


Before execution does not appear this problem, this address can be ping, consult everybody a great god exactly is what went wrong,
