So far when we talked about serverless IoT cloud we focused only on one way communication, devices sending telemetry data to the cloud. But in order to have a complete IoT solution, we need to be able to control our devices as well, by sending commands back to them.

LoRa is a low power long range wireless protocol that operates in a lower frequency spectrum than WiFi, ZigBee and Bluetooth. This enables IoT use cases not possible with the shorter range technologies. And, you can use Rust!

Pushing temperature readings in JSON structures to the cloud is fun, but more fun is to restart your pods by saying: "Hey Rodney, …". It also is a nice demo, and a good test, to see what fails when your Content-Type is audio/wav instead of application/json.

If we start living the async lifestyle, we can potentially get more use out of our limited hardware resources. Maybe not, but it's worth exploring. Let's explore.

The BBC micro:bit is a popular development kit often used to teach kids how fun programming can be. Lets see how we can hook it up to the cloud!

async/await within Rust is a convenient way to gain parallelism, even on an embedded device where we ostensibly have exactly one userland thread by default.

Minikube is a convenient tool for developing cloud services on your laptop, but how can you access them from your IoT device? In this article, we'll walk through deploying the drogue-cloud project on minikube and then use some drogue crates to post data to its knative endpoint via an ESP8266 WiFi module.

Exchanging messages with devices is great. As I tried to explain in the last blog post about the cloud side of things, having a modular system, and normalizing the transport protocol can make things a lot easier. However, exchanging messages is only the first step towards an IoT application.

Up until now, we have focused on "Rust on embedded devices", at least when it comes to writing blog posts. Let's change that.
