Cool Blue BlinkenLED for #PineCone #BL602 @PINE64 ... Tells us when it's transmitting #LoRa Packets ... As we run the LoRa Field Test in the wild

https://youtu.be/wCEx-nvDiuQ

Let's make our #LoRa Field Test easier ... #BL602 will auto transmit a LoRa Packet every 10 seconds as we roam in the wild

#RISCV #BL602 and #Arm #nRF52840 ... Happily United ... Thanks to #LoRa! 👍

#WisBlock receives perfect #LoRa packets from #BL602 ... We're done yay! 🎉 Tomorrow we shall take a walk ... And discover the real-world wireless range of LoRa!

Default #LoRa Parameters for #WisBlock and #BL602 ... Are already the same! Spooky Serendipity 🤔

#WisBlock will receive #LoRa packets from #BL602 ... Let's sync up the LoRa Parameters across WisBlock and BL602 ... Life gets Easy with Serendipity! 👍

What do #WisBlock #Arduino, #RISCV #BL602 and Apache #Mynewt OS have in common? They're using the same #LoRa driver code from Semtech! Serendipitous Discovery 😂

#WisBlock #Arduino Firmware for receiving #LoRa packets ... Runs OK with PlatformIO ... Code looks surprisingly similar to our BL602 LoRa code 🤔

And now PlatformIO flashes OK to #WisBlock! ... Maybe earlier I was staring at the WisBlock lights too long and it timed out 🤔
