Hi,

I try to connect to my mosquitto broken on my local network.

But I cannot connect and get error : -1.

I get this log when trying to connect:

I can provide the script is required.

is this normal:

esp> AT+CIPDNS_CUR=0 ...sent esp> ERROR ...error esp ERROR: expected OK got ERROR esp> AT+CWDHCP_CUR=1,1 ...sent esp> ERROR ...error esp ERROR: expected OK got ERROR

I know I can HTTP connect to my server and get the html code. Now I'm trying to connect to MQTT broker on another port.

Anything I can try ?

Thanks for your help !

you didn't switch the library to AT 2. see the README
