Lup Yuen Lee 李立源#RAKwireless WisBlock nRF52840 MCU + #LoRa Transceiver ... Super excited to start LoRa coding!
And now PlatformIO flashes OK to #WisBlock! ... Maybe earlier I was staring at the WisBlock lights too long and it timed out 🤔
#WisBlock #Arduino Firmware for receiving #LoRa packets ... Runs OK with PlatformIO ... Code looks surprisingly similar to our BL602 LoRa code 🤔
https://github.com/lupyuen/wisblock-lora-receiver/blob/main/src/main.cpp
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 😂
https://github.com/lupyuen/bl_iot_sdk/blob/lora/customer_app/sdk_app_lora/sdk_app_lora/radio.h
#WisBlock will receive #LoRa packets from #BL602 ... Let's sync up the LoRa Parameters across WisBlock and BL602 ... Life gets Easy with Serendipity! 👍
https://github.com/lupyuen/wisblock-lora-receiver/blob/main/src/main.cpp
Default #LoRa Parameters for #WisBlock and #BL602 ... Are already the same! Spooky Serendipity 🤔
https://github.com/lupyuen/wisblock-lora-receiver/blob/main/src/main.cpp
#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!
#LoRa #BL602 Field Test Kit ... #PineCone #RISCV BL602 @PINE64 with RF96 LoRa Transceiver ... In a Permeable Paper Box with Battery ... And #Pinebook Pro for Urgent Field Maintenance 😉
Let's make our #LoRa Field Test easier ... #BL602 will auto transmit a LoRa Packet every 10 seconds as we roam in the wild
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
Cool Blue BlinkenLED for PineCone BL602 LoRa Field Test
Timestamp every #LoRa Packet received by #WisBlock ... We'll match these with the Geocoded Timestamped Photos that we'll snap as we walk ... It's like Pokemon Snap but for LoRa Packets
https://github.com/lupyuen/wisblock-lora-receiver/blob/main/src/main.cpp#L118-L140
This #PineCone #BL602 photo is Geocoded and Timestamped ... We'll match this with the log of #LoRa Packets received by #WisBlock
...And just to clarify: Geocoded Timestamped Chicken Rice didn't come from the Geocoded Timestamped Chickens earlier 😉
#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
Battery is nearly full after one hour of roaming with #LoRa and #BL602 ... Good sign!

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

In times of Disaster ... A #LoRa Radio would be incredibly useful 🤔
Cleaning up the #WisBlock Arduino Log for easier analysis ... Before the 2 km #LoRa Field Test

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
We stream the #WisBlock Arduino Log to YouTube with open-source OBS Studio
Testing your #LoRa Sensor the easy way ... With RAKwireless WisBlock! All shall be explained here...
Here's how we connect RAKwireless WisBlock #LoRa Module ... Easy as a piece of no-bake cake! 🍰
