Trying to setup MQTT Server for RAK 4630 Weather Station

Carl are you sure this wind sensor you recommended works with this rak 4630 board?

That wind sensor has the same PN as what we used on the solution example so that will work.

Also, any wind sensor will work with RAK4630 as long as you can get its data.

We were able to send it data and verified that it was the same as the datasheet and the sensor never responds back. We verified from the datasheet you sent me here on the oscilliscope as you can see, and the sensor does not respond.
