#### Abstract #### We need a Raspberry Pi Pico W to be able to send and receive JSON encoded data to AWS via MQTT over the NB-IoT cellular network. #### Progress #### We are well down the road on this with everything working using the built in WiFi on the Pico. We are using AWS Shadow to keep device config sync'd and then normal pub/sub to and from AWS topics with "AWS IoT rules" setup to store incoming MQTT data on each topic to Dynamo DB.
