MQTT connection

[felmue]

Hello @travisstdenis

have you tried to connect to test.mosquitto.org? Does that work or are you getting the same error?

Thanks
Felix

@travisstdenis The connection blocks need to bee in the loop not the setup.

@felmue i couldn't get a connection to test.mosquitto.org but i could for Adafruit. I setup this connection

I get a nonsense error on the screen about some unrelated rectangle UI block in the setup about

TypeError: extra keyword arguments given

When I look at the serial data i get:

>>> E (8014) mqtt_client: Error create mqtt task
E (23515) mqtt_client: esp_mqtt_client_init(800): Memory exhausted
E (23515) mqtt_client: Client was not initialized
E (23516) mqtt_client: Client was not initialized

I have tried this several ways. with and without the https:// in the server, with keepalive values of 0 or 300, in and out of the "if connected to wifi" block. The image shows the only way I've gotten some kind of response that gets me closer.

@ajb2k3 I have the "MQTT Apply For Messaging" block in the Loop. Everything I have seen has the connection parts in the Setup. Are you saying I need to have the MQTT Init block from the setup in the Loop?

Hello @travisstdenis

please have a look at my example for test.mosquitto.org and io.adafruit.com in the UIFlow2 Project Zone called: M5Core_MQTT_WLAN_UIFlow2.1.4

Thanks

@felmue that worked! So it was just the addition of those other WiFi blocks that did it. The Serial output had said Wifi connected before, but I guess not.

Hello @travisstdenis

@travisstdenis Can I ask how you even got the MQTT blocks in the UIFlow2. Am not seeing any MQTT at all in the GUI.

@felmue Can I ask a more basic question? I am not seeing the MQTT block in the UIFlow2 web guide? I see no way to add any "libraries" etc either. WhenI search with google or use the M5AI chat I get really that is is there if I used my API key. When is another item of question on how you enter that. I did install / download of UIFlow2 to M5 device and now the Screen gives me a key etc. Not sure where or what to do with this.

Hello @sbeeker

UIFlow2 doesn't use API keys. (Only UIFlow1 used them.) Are you sure you installed UIFlow2 firmware onto your M5Stack
device?

Use M5Burner from here to install UIFlow2 firmware (as an example for M5Core2) then use your browser to go to UIFlow2.

Thanks
