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

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?

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?
