LSN50V2 Downlink

Hello, I have started to deal with the TTN.
I have a LSN50V2.

The LSN50v2:

When I send a downlink, it is not processed until the Device send an uplink.

Is it possible that when I send a downlink to the device, it is received immediately?

Please DO NOT double post - it splits effort of the volunteers and contributors and clutters the forum.
