Hi,
The rssi and hardware gain are attributes of the phy driver. E.g. see the following example code how to read the rssi.
#include #include
int main(void)
{ struct iio_context *ctx = iio_create_local_context(); struct iio_device *dev = iio_context_find_device(ctx, "ad9361-phy"); struct iio_channel *v0; char buf[256]; int ret; v0 = iio_device_find_channel(dev, "voltage0", false); ret = iio_channel_attr_read(v0, "rssi", buf, sizeof(buf)); if (ret < 0) { fprintf(stderr, "Failed to read rssi: %d\n", ret); exit(1); } printf("rssi: %s\n", buf); return 0;
}
The AD9361 has a built-in FIR filter that can be loaded with custom coefficients. Which means you can implement your own low-pass filter. The Filter Design Wizard allows you to create your custom filters.
