Dinesh Lama

I am running a qt quick application on android which is using qtmqtt to puslish and subscribe data from remote computer. Here when i publish data from this application and try to subscribe in remote machine using

mosquitto_sub -h 192.168.1.69 -t "#"

I'm getting error:

Error: Connection refused

How should i solve this issue?

Hi
If the android is running on a mobile net it's not possible to talk to it from outside.
Smart phones on mobile net are behind a NAT firewall and its not open for external devices so
if your android is "the server" this wont work.

Android is connected on local router through wifi.

Hi,

Which port are you using on your device for your broker ?
Can you connect to it directly ?
Did you check that there's something flowing with a tool like wireshark ?

I used the default port of mqtt i.e 1883. I can ping the ip address of android but can't login with ssh inside the system.

Android is kind of vague, which version is it ? Running on what hardware ? Do you have root access to it ?
