Frequently Asked Questions

What frequency should I use for drone telemetry?

For EU: 868 MHz. For US/Australia: 915 MHz. 433 MHz is also popular for shorter-range applications. Check local regulations.

SX1276 range for drones?

With a good antenna and clear line of sight, SX1276 LoRa can achieve 10-15km range at low data rates. At higher data rates, range is shorter.

Is SX1276 compatible with ESP32 LoRa?

Yes, ESP32 with LoRa module (SX1276) can communicate with any SX1276-based device. Protocol must match (same spreading factor, bandwidth, coding rate).
