  • Ranges of "over 10km in rural areas" are cited (antennae unspecified) but there is every reason to expect that this range can be exceeded in ground to air operation with 'sensible' antennae. LORA utilises 'spread spectrum' techniques to achieve astounding-but-true real-world link budgets of typically 168 dB. eg -148 dBm RX levels at 100 mW tx ...
  • Since both the Bluetooth detection and name lookup process are probabilistic, discover_devices() will sometimes fail to detect devices that are in range, and lookup_name() will sometimes return None to indicate that it couldn't determine the user-friendly name of the detected device. In these cases, it may be a good idea to try again once or ...

SRD (Short Range Device) frequency bands at 315, 433, 868, and 915 MHz, but can easily be programmed for operation at other frequencies in the 300-348 MHz, 387-464 MHz and 779-928 MHz bands. The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has
