Someone captured this #LoRa Chirp with HackRF One SDR ... Isn't this beautiful?

Captured the Legendary #LoRa Chirp! (The helix thingy)

1️⃣ Enable #LoRa SX1276 Power Amplifier 2️⃣ Increase Airspy sample rate to 10 MHz ... LoRa Packets never looked better!

Let's zoom into the #BL602 #LoRa Packet ... And hunt for the LoRa Chirp!

https://pubs.gnuradio.org/index.php/grcon/article/download/8/7/

CubicSDR software works better with Airspy ... Here's the #BL602 #LoRa Packet (64 bytes) centered at 923 MHz with bandwidth 125 kHz

Nope Airspy SDR couldn't sniff our #BL602 #LoRa at 923 MHz ... Though it sniffed others thru the Faraday Cage (erm) Pot 🤔

https://github.com/lupyuen/bl_iot_sdk/blob/lora/customer_app/sdk_app_lora/sdk_app_lora/demo.c#L220-L270

#BL602 + #LoRa SX1276 + Airspy SDR ... Inside an improvised Faraday Cage 🫕 ... It really works!

But today we shall spy on #BL602 + #LoRa ... With an #Airspy R2 Software Defined Radio 📻

Someday we shall pack #PineCone #BL602 @ThePine64 with #LoRa ... Into this cute clear Junction Box
