Downlink messages limitations over TTN


Are there some limitations using TTN to send downlink trafic to end-nodes ?

I’ve read on the forum that LoRa class C isn’t implemented yet, on the other hand, I’ve read some topics about downlink messages over TTN so I’m confused.

Thanks in advance !

Class A allows downlink traffic in a small window after uplink. You can queue a message to be transmitted on the next uplink.
