Miflora connect to Thingspeak?

I have a DOIT ESP32 devkit v1. I plan to use it for Miflora/ bluetooth. I

I compiled in Platformio uncommenting esp32-dev-ble. It uploaded to the board. I accessed the Wifi and connected it to my network. I see that it gets a lease from my router.

What do I have to do next? I have mosquitto installed if that helps. I also installed MQTT explorer and put the details in. After a few seconds of clicking ‘connect’ it says ‘disconnected from server’

The end result is to see my Miflora devices on Public Channels - ThingSpeak IoT I’ve never used MQTT before and have only the vaguest of idea of how it works.

Still wondering what to do next.

Anyone? Shall I just do this on a Pi Zero instead?

If you go to mosquitto log you can see the connection states from the different devices. Maybe it could help you.
