Testing our #LoRaWAN Driver on #PineDio Stack BL604
https://github.com/lupyuen/bl_iot_sdk/tree/pinedio/customer_app/pinedio_lorawan
Need to swap MISO and MOSI Pins due to a #BL604 SPI quirk ... Also note the quirky SPI Polarity-Phase
Boot our #BL604 #LoRaWAN Firmware and enter these commands to: 1️⃣ Join the LoRaWAN Network 2️⃣ Transmit a LoRaWAN Data Packet

Our #LoRaWAN Gateway (ChirpStack) accepts the Join Network Request from #PineDio Stack ... And receives the Data Packet yay! 🎉
https://lupyuen.github.io/articles/lorawan#view-received-lorawan-packets
Our ChirpStack #LoRaWAN Gateway shows the Data Packet received from #PineDio Stack ... Yep packet contents are correct!

SDR Spectrum Analyser shows this beautiful #LoRa Chirp transmitted by #PineDio Stack SX1262 ... Looks OK but why are there "Fireflies"? 🤔

https://lupyuen.github.io/articles/lorawan2?17#seeking-volunteers
Now serving the #LoRaWAN Community ... And relaying other folks' messages to The Things Network!
#LoRaWAN The Things Network doesn't have good coverage in Singapore ... Let's do better!
@icedquinn Yeah sigh 🙄
i shrugged like "you know there's nothing special about the military stuff right? you can make frequency hopping systems out of any computer controlled radio
"
@lupyuen -- How about not storing Security Keys on a public facing server?
Remember to deselect all other SPI Peripherals when testing #LoRa SX1262 on #PineDio Stack BL604
