@leopold,
I have those links and have used them.
What we want to build is, downlink initiated communication. By attaching gpio status on downlink acknowledgement from RAK811 node. As we can send data on uplink acknowledgement packet.

We able to receive class c downlink, only don’t know is where the acknowledgement is need to manipulate to send device gpio status

Thanks

Hi @urvil,

The ACK for the downlink confirm packet is now generated in LoRaWAN stack, and there is no RUI API to customized the content of the ACK packet now.

Hello @Fomi,

When will this downlink ack customization RUI API will be avaliable ?, we need to inform this time.

Thanks
