Reception problem

Hello,

I’m running an LoRaWAN application, I’m using a LoRaWAN module (RN2483) with a Raspberry Pi3, so I’m using the UART liaison to communicate.

I’m triyng to communicate with a LoRaWAN Gateway, the MultiConnect Conduit – Application Execution Platform _ MTCDT-210A Firmware 1.4.1, but when I send a little “Hello World” with the RN2483 module I saw on the gateway logs : “May 22 15:37:51 mtcdt user.warn lora-network-server: GW:00:80:00:00:00:00:c2:fa|FRAME-RX|REJECTED|REASON: Frame too short VALUE: 58″. I’m sending the message with the command “radio tx 48656c6c6f20776f726c64″, 48656c6c6f20776f726c64 means “Hello world” in hex.
I didn’t know where this problem come from.

If someone can help me, it will be appreciated.

Thanks for your replies.
