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

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

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!

#WisBlock captured One Hour of #LoRa Packets from #PineCone #BL602 yay! 🎉 Now to match the Timestamps with the Geocoded Photos / Chickens / Chicken Rice ... Here's the log:

https://github.com/lupyuen/wisblock-lora-receiver/blob/main/logs/0922-1024.log

#PineCone #LoRa Field Test makes me hungry for Geocoded Timestamped Chicken Rice

This #PineCone #BL602 photo is Geocoded and Timestamped ... We'll match this with the log of #LoRa Packets received by #WisBlock

#PineCone #BL602 @PINE64 with #LoRa Transmitter ... All packed in my backpack ... Let's go Pikachu!
