Function pamoja_lorawan_end_device_heard 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_lorawan_end_device_heard(
    device: *mut PamojaLorawanEndDevice,
    frame: *const u8,
    frame_len: usize,
    snr_db: i8,
    out_heard: *mut PamojaLorawanHeard,
    out_payload: *mut *mut PamojaBuffer,
) -> PamojaStatus

Reads a frame heard in one of the receive windows of the last transmission, without saying which.

A downlink may be as long as the faster of the two windows allows. When the radio knows the window, pamoja_lorawan_end_device_heard_in holds the frame to that window’s own limit.

Arguments

• device - the device.
• frame - the bytes the radio received.
• frame_len - their length.
• snr_db - the frame’s signal-to-noise ratio, which a DevStatusAns reports.
• out_heard - receives what the frame was.
• out_payload - receives the application payload of a data frame, and null for a join.

Returns

PamojaStatus::Ok on success. A payload buffer, when set, must be released with pamoja_buffer_free.

Errors

Returns a failing status with the reason on pamoja_lorawan_end_device_error: nothing pending, another device’s frame, a replayed or far-ahead counter, a refused join accept, or a frame that did not decode.

Safety

device must be a live handle, frame must point to frame_len readable bytes when that is non-zero, and the out pointers must be writable.
