I have a Rak 7258 and I am using the on-board Lora-Server.
I am sending downlink messages to the server by MQTT to the downlink topic.
I have set my application server to encode/decode as HEX string.
The downlink message I want to send to the node is needs to be finally this ascii string at the node application:
I see that I cannot sent that to the Rak lora Server in this format as it will not send a down link, so I convert it to HEX bytes:
47 50 49 4f 2c 32 2c 31
Now the Rak sends a downlink, great, however when I look at the payload that was sent I see this:
“FRMPayload”: "01 EA 0A F5 82 D3 A7 BC
The Rak config manual - RAKLoRaWANIndustrialGatewayWisDeviceSeriesRAK7249/58Version1.7|October,2019
says (on page 37)
Can anyone help me understand this? do I need a special decoder on my node? how can I just send plain HEX bytes in the downlink?
