Hello, i’m using lora ebyte e30-170t27d.
I’m trying to send message to receiver and after sending message i wait till response, after short amount of time i get response.
The problems is my distance of communication between sender and receiver is too low (i get errors after 100 meters and after 100m i can’t receive any answer message).
What should i check? i checked antennas and supply voltage.
And also i tried to use e220-400t22d – same result (a little bit better, i get errors after 150m i can’t receive any answer message).
Any suggestions of what to do next?
Thank you.
