First you really shouldn’t send printable strings, but more efficiently encoded messages. In addition to the payload body itself, you also have most of the range of the port to work with, excluding reserved values of 0 and above some number in the 200’s.
“FRMPayload”: "01 EA 0A F5 82 D3 A7 BC
LoRaWan AES encrypts data when it is transmitted. The FRMPayload is a still-encrypted portion of the packet containing your application payload, but it is not yet your application payload. It will only become your application payload again after decryption by the LoRaWan stack on your node.
Ultimately your question comes down to understanding how the LoRaWan stack of your node handles downlinks and presents them to the application part of your node - this is really a question about your node.
Thanks Chris.
I see now, I found out that the node I was working on does not support downlink so I guess I will go back to trying something else.
So far the RaK gateway has been very reliable, Im going to try some work with the Wisblock nodes next,
Cheers

Hi @Chirpper I’m trying to send a downlink to my device, but I’m not abble to do this. Could you help me saying or showing how you configured you RAK 7258?
