Is there any setting I can do on WiFi Lora 32 v2.1 to reduce the coverage of LoRa?
I believe I am already using the minimum:
- 2dBm Tx power
- Spreading factor 7
- Banwidth 250KHz
- Region 868MHz
-on our recent test, I can communicate 3KM.
But if there is any setting I can add on the receiver maybe like some RSSI threshold.
To further explain my contradicting question, my setup is like this:
I wanted to use LoRa for both short range and long range communication.
That is, WiFi Lora 32 v2.1 will serve as the receiver and multiple Cubecell AB02 will server as Transmitter in a star-network topology. I’m not gonna use LORAWAN.
I am having this problem http://community.heltec.cn/t/wifi-lora32-v2-with-cubecell-ab02-packet-lost/5790 for which I minimized my packet loss. However, I don’t have the best solution, such as in cases that there are other Lora devices in the area causing congestion and may cause my receiver not to receive from any paired transmitter. So I wanted to be able to control the range instead.
Thanks
