.connect always returns false on NodeMCU Amica (v1.0?) #21

Closed dantheman2865 closed 9 years ago

I spent some time trying the examples (mqtt_basic and mqtt_subscriber) and I could never get my device to register to the Mosquitto broker I'm running on a local server, that is to say .connect always returns false. I have verified that I get an IP, and I can see traffic going to and from the server.

I have a NodeRed instance running and I've never seen $SYS/broker/clients/total go above 1 (which is the NodeRed MQTT client).

I ran Wireshark on the server and here's the packets I see back and forth for each loop: client to server: SYN s to c: SYN, ACK c to s: ACK c to s: PSH, ACK (CONNECT message) s to c: ACK s to c: FIN, ACK c to s: RST, ACK s to ?: ACK

Here's the CONNECT message in wireshark: 0000 10 19 00 04 4d 51 54 54 04 02 00 0f 00 0d 61 72 ....MQTT......ar 0010 64 75 69 6e 6f 43 6c 69 65 6e 74 xx xx xx xx xx duinoClient

What else do you need to troubleshoot?

Thanks for your work, I'm looking forward to getting this working!

What version of Mosquitto are you using?

dantheman2865 commented 9 years ago

I'm running 0.15-2ubuntu1 It says that's a v3.1 broker, is that the problem? Let me try running the Mosquitto Debian repository rather than the Ubuntu repo.

Success! I solved this by updating my broker to a v3.1.1 broker (1.4.2a) that was in the ppa repository. Thanks for your help.
