Hi,
I make two arduino with lora sx 1278 18dbm and i have only 60 meters range transmission, i am using the lora lib example transmitter+ receiver. I not change the config of the sx1278 433 Mhz. Any idea for improve the range ?
Thank's for your answer.

Can you say which library you are using when you refer to 'the lora lib' you may know but there are several LoRa libraries so the forum does not know which one you are using, nor the LoRa settings in use ?
In particular see point 11 from the post at the top of the forum for some tips on how to ge the most out of a post and save a lot of everyones time;

Have you at any time, even briefly, operated the LoRa modules without an antenna ?

Tank you for your answer, i never use Lora module whitout antenna, and the lib is GitHub - sandeepmistry/arduino-LoRa: An Arduino library for sending and receiving data using LoRa radios.
Sorry for my english and if my post is not good
You need to change the example programs from the default frequency of 915Mhz.

Hello,
Thank you for your answer but my sx1278 is 433 Mhz frequency, i can change to 915 Mhz ?

The example programs for that library set the frequency of operation to 915Mhz.
That can damage 433Mhz modules and can produce symptoms of extreme short range.
The example programs need to be changed so that the frequency of operation is 433Mhz.
If you post the code you are actually using its much easier for the forum to help you.

Hi,
What is the best config for long range !
Thank's
Which part of the phrase "post your code" do you not understand?
Use code tags for posting code, as described in the "How to use this forum" post.

I change the frequency in example to 433 Mhz,

And ?
Are you willing to tell us what affect this had on the range ?
Or is that a secret ?
no it's not a secret, it's just that my sx1278 module is 433 Mhz
