Sorry, two option in the same demo code

printf(" [-r/-t/-x/-s] select app mode (default=r)\n");
printf(" r - RX\n");
printf(" t - TX\n");

Are you talking about here, with two devices, one set to APP_MODE_RX and the 
other set to APP_MODE_TX?

apps\examples\sx127x_demo\sx127x_demo.c

int main(int argc, FAR char *argv[])

 /* Initialize buffer with data */

 for (i = 0; i app_mode   = APP_MODE_RX;

Looks that there are two app examples, one sender and other receiver

Then I use two same STM32 boards to test Lora sx127x, one for receiving and 
one for sending. How should I set it, in nuttx code or menuconfig?

Well, I tested the receive with other module transmitting lora, but not running 
NUTTX

sx127x has been executed successfully。The operation information is as follows:
nsh> sx127x
Start sx127x_demo
LORA modulation
Set frequency to 930000000<tel:930000000>
Set power to 14
Waiting for data

But keep waiting for data,There should be more than two devices for 
communication here. How to set it up?
