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[])
{
#ifdef CONFIG_LPWAN_SX127X_RXSUPPORT
struct sx127x_read_hdr_s data;
#endif
struct sx127x_chanscan_ioc_s chanscan;
struct args_s *args;
struct timespec tstart;
struct timespec tnow;
uint8_t buffer[TX_BUFFER_MAX];
uint8_t opmode;
uint8_t i;
int ret;
int fd;
/* Initialize buffer with data */
for (i = 0; i app_mode = APP_MODE_RX;
args->modulation = APP_MODULATION_LORA;
args->frequency = CONFIG_EXAMPLES_SX127X_RFFREQ;
args->power = CONFIG_EXAMPLES_SX127X_TXPOWER;
args->interval = CONFIG_EXAMPLES_SX127X_INTERVAL;
args->time = CONFIG_EXAMPLES_SX127X_TIME;
args->datalen = CONFIG_EXAMPLES_SX127X_TXDATA;

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

sx127x has been executed successfully。The operation information is as follows:
nsh> sx127x
Start sx127x_demo
LORA modulation
Set frequency to 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?
