dwm_dev_status_get

This command reads the device status. The battery level is unavailable when used in the user application (on-chip library), as it allows for the use of the ADC peripheral.

void dwm_dev_status_get(dwm_mac_addr_list_t *mac_addr_list)

Parameters

• input – (none)

• output – Status code, uptime, battery_level, temperature

• uptime – 32-bit unsigned integer (uptime in seconds)

• battery_level – 8-bit unsigned integer (battery level in percents, not available in the user application library)

• temperature – 16-bit integer (temperature in °C)

C code example

dwm_dev_status_t status;
int rv;
if (rv == DWM_OK) {
   printf("uptime=%lu\n", status.uptime);
   printf("temperature=%d\n", status.temperature);
} else {
   printf("can't read device status, error %d\n", rv);
}
