Wireless Stick Lite(V3) and LORA_SPREADING_FACTOR

#1

Hello,

I am using the ino codes from:


and

for my data transmission, but I need to increase the range. I increased the LORA_SPREADING_FACTOR value to 8-12 on both sites. Unfortunately, the transmission no longer works. It works fine with a value of 7.
I also tried increasing the values: RX_TIMEOUT_VALUE, BUFFER_SIZE. That didn’t help either. I’m using the Wireless Stick Lite(V3) device.
Could you please advise me?

I just tested it, and it works properly at SF12, 9, and 7. Besides modifying the SF, what other changes did you make?

Hello richard3366,

Thank you for your response and for trying it out! In the settings, I only tried changing the SF on both sides. Otherwise, I have the program modified on both the transmitter and receiver sides due to sensor connections.

On the receiver, I have a BME688 sensor and I send data from the sensor and transmitter to the database via WiFi.

On the transmitter, I have BME280, MLX90614, and BH1750 sensors.
