Not sure why my rustdoc articles stopped working with Prism.js ... But here's my hacky fix 🤔

#PineDio Stack BL604 sends CBOR Sensor Data to #TheThingsNetwork ... And gets visualised by #Grafana 🎉

https://lupyuen.github.io/articles/grafana?5#grafana-dashboard

Here's how we encode Sensor Data with #TinyCBOR ... And transmit over #LoRaWAN

https://github.com/lupyuen/bl_iot_sdk/blob/cbor/customer_app/pinedio_lorawan/pinedio_lorawan/lorawan.c#L893-L1050

Yep #TinyCBOR compresses our Sensor Data on #BL602 before transmission yay! 🎉

These are the changes when we encode a second Key-Value with #TinyCBOR: { ... , "l": 2345 }

https://github.com/lupyuen/bl_iot_sdk/blob/cbor/customer_app/pinedio_cbor/pinedio_cbor/demo.c#L68-L139

Here's how we encode this with #TinyCBOR ... { "t": 1234 }
