LoRa for Hackers: Testing Long-Range Remote Control in the Real World

See how LoRa modules can be used to trigger a camera speedlight from nearly a mile away — no Wi-Fi or cellular required! 📡💡 https://null-byte.wonderhowto.com/how-to/lora-range-test/

LoRa (long-range) technology is commonly used for IoT applications, allowing low-power, long-distance communication without internet connectivity. But how far can it really go? In this episode of Null Byte, we put LoRa to the test using a camera speedlight to visually measure its range in an urban environment.

By integrating a LoRa module with a Bluetooth Nugget and a relay-controlled camera flash, we explore how LoRa performs in real-world conditions. This experiment is just one example of how far hackers can push LoRa’s range when remotely controlling their own devices. We also discuss how tools like software-defined radios (SDRs) and the Flipper Zero can be used to verify LoRa transmissions.

🔥 What we cover in this video:
✔️ How LoRa technology works and its real-world applications
✔️ Setting up a LoRa transmitter and receiver using Bluetooth Nuggets
✔️ Using a relay module to trigger a speedlight
✔️ Testing LoRa range in an urban environment
✔️ Factors affecting LoRa signal strength and transmission distance
