Chris showed everyone how to write a lambda in Rust and deploy it to AWS. He wrote an excellent blog post describing the process in detail. The project uses the AWS Lambda Runtime and the lambda-web crate, which adapts requests from API Gateway V2 passed through the Lambda runtime to Rocket. Actix and Warp are also supported Rust web frameworks.

Async Bluetooth on the BBC micro:bit Microcontroller via @jacobrosenthal

Repo: https://github.com/jacobrosenthal/microbitv2-rs

Jacob wrote an example async Bluetooth LE program for the BBC micro:bit microcontroller.

The project makes use of the following crates:

The program allows us to read and write data to a dummy BLE characteristic, which we did using the nRF Connect app (available for Desktop, Android, and iOS).
