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

Logic Analyser shows PineDio Stack #BL604 talking to #LoRa SX1262 over SPI

Our ChirpStack #LoRaWAN Gateway shows the Data Packet received from #PineDio Stack ... Yep packet contents are correct!

https://lupyuen.github.io/articles/lorawan#view-received-lorawan-packets

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

Boot our #BL604 #LoRaWAN Firmware and enter these commands to: 1️⃣ Join the LoRaWAN Network 2️⃣ Transmit a LoRaWAN Data Packet

Need to swap MISO and MOSI Pins due to a #BL604 SPI quirk ... Also note the quirky SPI Polarity-Phase
