Analysing the #LoRa Network Coverage ... Based on the LoRa Packets received by RAKwireless #WisBlock

https://lupyuen.github.io/articles/wisblock?29#analyse-the-lora-coverage

Here's how we conduct a #LoRa Field Test ... With #PineCone #BL602 @PINE64 ... And RAKwireless #WisBlock

https://lupyuen.github.io/articles/wisblock?28#lora-field-test

Here's how we run #LoRa Firmware on RAKwireless #WisBlock ... To receive LoRa Packets over the airwaves

In the dark ... RAKwireless #WisBlock receiving #LoRa Packets from #PineCone #BL602

https://lupyuen.github.io/articles/wisblock?10

On RAKwireless #WisBlock we handle received #LoRa Packets with a Callback Function

On RAKwireless #WisBlock, here's how we init the #LoRa Transceiver ... Remarkably similar to #BL602 LoRa 👍

https://lupyuen.github.io/articles/wisblock?9#setup-function

Here's how we connect RAKwireless WisBlock #LoRa Module ... Easy as a piece of no-bake cake! 🍰

https://lupyuen.github.io/articles/wisblock?6#connect-wisblock

Testing your #LoRa Sensor the easy way ... With RAKwireless WisBlock! All shall be explained here...

https://lupyuen.github.io/articles/wisblock?5

If I can't see the #LoRa Packets captured by #WisBlock in Real Time ... How far shall I walk during the LoRa Field Test? 🤔 ... I'll do a YouTube Live Stream of the WisBlock #Arduino Log ... Lets me watch the LoRa packets received as I walk

Cleaning up the #WisBlock Arduino Log for easier analysis ... Before the 2 km #LoRa Field Test

In times of Disaster ... A #LoRa Radio would be incredibly useful 🤔

#BL602 #LoRa packets received by #WisBlock ... LoRa works great 300 metres away! Will have to walk farther (and eat more)

Battery is nearly full after one hour of roaming with #LoRa and #BL602 ... Good sign!
