Interop AU915, test (2.2.5 RX2 window) failed

Hello,

While testing the AU915 device with Interop Engine, the test fails at 2.2.5.

The error message is:
"Ignore DevStatusReq because not sent through RX2... DevStatusReq unconfirmed downlink has been queued. Device did not respond to commands sent through RX2 as expected (ratio 0 < 0.95)."

Upon reviewing the server packets, it's confirmed that after receiving the DevStatusReq, the device does respond with DevStatusAns in the next uplink. I tried two different response approaches:

  1. After receiving the DevStatusReq in RX2, the device responds with DevStatusAns in the next uplink, with an uplink interval of 5 or 10 seconds.
  2. After receiving the DevStatusReq in RX2, the device immediately responds with DevStatusAns, similar to how it would handle a Confirmed Downlink.
Any idea is welcom.
