Does ChirpStack send ACK messages to devices?

Devices

Hi all,

I am in conversation with a vendor as to why their devices have stopped emitting uplinks. I just wanted to get official confirmation from anyone if ChirpStack does indeed send periodic downlink to devices, or answer ACK uplinks from devices.

Their idea is that ChirpStack does not reply and that is why their devices do not continue to emit.

Thanks,
Jake

If you send a confirmed uplink then ChirpStack will send an ACK as downlink respone.
