Decoding CBOR in #GoLang

https://lupyuen.github.io/articles/grafana?8#decode-cbor-in-go

Why we encode #TheThingsNetwork Sensor Data with CBOR (instead of JSON)

Filtering Sensor Data with #Grafana

Visualising #TheThingsNetwork Sensor Data with #Grafana

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

https://github.com/lupyuen/lupyuen.github.io/blob/master/scripts/gen-articles.sh#L7-L52

#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! 🎉

https://github.com/lupyuen/bl_iot_sdk/blob/cbor/customer_app/pinedio_cbor/pinedio_cbor/demo.c#L9-L139

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 }

https://github.com/lupyuen/bl_iot_sdk/blob/cbor/customer_app/pinedio_cbor/pinedio_cbor/demo.c#L9-L66

#TinyCBOR works great for compressing our Sensor Data before transmission

Let's port #TinyCBOR to #BL602 and BL604

Adding the #Grafana Data Source for our MQTT Server at #TheThingsNetwork

https://lupyuen.github.io/articles/grafana?4#configure-grafana-data-source

Here's how we install #Grafana ... And our Custom Data Source for #TheThingsNetwork

https://lupyuen.github.io/articles/grafana?3#appendix-install-grafana-and-data-source

How we enable the MQTT Server at #TheThingsNetwork

https://lupyuen.github.io/articles/grafana?2#configure-the-things-network-mqtt

Visualising #TheThingsNetwork Sensor Data with #Grafana ... All shall be explained in this article

https://lupyuen.github.io/articles/grafana?1

But to visualise historical Sensor Data from #TheThingsNetwork, we should store the data in Prometheus and push to #Grafana

https://github.com/lupyuen/the-things-network-datasource

We have just visualised #TheThingsNetwork Sensor Data in #Grafana with our custom data source

https://github.com/lupyuen/the-things-network-datasource

Our Data Source for #TheThingsNetwork MQTT ... On a #Grafana Dashboard 🎉

https://github.com/lupyuen/the-things-network-datasource

CBOR Payloads now decoded OK ... By our #Grafana Data Source for #TheThingsNetwork yay! 🎉
