Function pamoja_lorawan_session_decode 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_lorawan_session_decode(
    session: *const PamojaLorawanSession,
    bytes: *const u8,
    bytes_len: usize,
    fcnt: u32,
    out_rx: *mut *mut PamojaLorawanRx,
) -> PamojaStatus

Decodes a received data frame: verifies the MIC, then decrypts the payload.

Arguments

• session - the session the frame belongs to.
• bytes - the frame exactly as it came off the radio.
• bytes_len - its length.
• fcnt - the full 32-bit frame counter expected for this frame; its low 16 bits must match the counter the frame carries.
• out_rx - receives the decoded frame.

Returns

PamojaStatus::Ok on success, with *out_rx set to a handle the caller must release with pamoja_lorawan_rx_free, PamojaStatus::Auth if the MIC does not verify or the counter does not match, or PamojaStatus::Codec if the frame is truncated or is not a data frame.

Safety

bytes must point to at least bytes_len readable bytes when that length is non-zero, and out_rx must point to a writable *mut PamojaLorawanRx.
