(sorry about the double post)

I'm not able to use the I2C variant as i didn't get that sensor from M5stack, its one of these:

I need it to be water resistant for this setup.

Hi all,

I'm fairly new to UiFlow however I have been C++ coding with Arduino for a while now and though I would try using the M5Stack gear.

I purchased a Core device, a EXTIO2 and a number of UltrasoundIO (GPIO model). I want to build a test that reads the distance from the UltrasoundIO connected to the EXTIO2, however im not sure how to reference the pins within the EXTIO2 in the UltrasoundIO configuration or methods

Can anyone assist or provide a basic example ?

I am very new to M5Stack, however have been working with ESP for quite some time and thought id give UiFlow 2 a go.

I have created a project that connects to my wifi (secured vlan) and I'm trying to set up MQTT to a local MQTT broker (not public one) the vlan with the M5Stack does not have internet access. I have pushed my code to the device and it loads as expected, however MQTT is failing and im seeing the following in the log:

E (3139) esp-tls: [sock=56] delayed connect error: Connection reset by peer
E (3140) transport_base: Failed to open a new connection: 32772
E (3143) mqtt_client: Error transport connect

On top of that, I can see the device trying to connect to a public IP on 1883 (the MQTT port), however my code is configured to use a local port for MQTT.

I'm not sure what underlying code is trying to connect to a public IP (104.208.113.224) but the fact i haven't coded the device to connect externally and its trying to is very suspicious, can anyone explain what could be happening here ?
