[Downlink] no error on API queue, ack received in live framelog but cannot receive any downlink on device.

Hi,

I’m trying to do a downlink. Last week it worked well my node can receive a downlink.
But today (with the same setup with everything) it not work anymore.

here is my downlink payload

and this is response body and code when I click “Try it out!” button

my device profile setup is ABP and class C.
and here is RX, Frequency parameter. I’m not sure how to set this patameter(s).

and here you will see that I can receive ack in LIVE DEVICE DATA

and also in LIVE LORAWAN FRAMES as well

any ideas?

That ack doesn’t seem to correspond to the ConfirmedDataDown: it has an earlier timestamp than the downlink.

@Apirak_Pumprapai could you fix it? I’m having the same problem

Hi sir, Could you send the downlink to end device?. I’ve been stuck for a long time
