Question 1

How do I set up uPyLoRa on my ESP32 board?

Accepted Answer

Refer to the linked articles in the README for tutorials; you'll need to flash MicroPython on your ESP32 and install the driver, which is optimized for Wemos TTGO LORA32 boards with specific pin mappings.

Question 2

What's the difference between uPyLoRa and Arduino LoRa libraries?

Accepted Answer

uPyLoRa is designed for MicroPython on ESP32, offering a Python-based interface for easier scripting, while Arduino libraries use C/C++ and are tailored for the Arduino ecosystem. Choose based on your preferred language and hardware platform.

Question 3

Does uPyLoRa support LoRaWAN Class A devices?

Accepted Answer

Yes, but LoRaWAN support is handled in a separate repository (uPyLoRaWAN), which likely includes Class A; check that repo for protocol-specific details and implementation examples.

Question 4

Can I use uPyLoRa with other ESP32 LoRa boards besides Wemos TTGO?

Accepted Answer

While optimized for Wemos TTGO LORA32, you may need to modify pin configurations or driver settings for other boards, as the code is hardware-specific and not universally plug-and-play.

Question 5

How to send sensor data over LoRa using uPyLoRa?

Accepted Answer

After installing the driver, use the SX127x interface to initialize the LoRa module and send data packets; look for example code in the repository or the linked tutorials for practical implementations.

Question 6

Is uPyLoRa good for battery-powered IoT nodes?

Accepted Answer

Yes, LoRa is designed for low power consumption, and uPyLoRa on ESP32 can be configured with sleep modes, making it suitable for remote sensor networks that require long battery life.
