Having trouble with Gateway and LoRa example

Hi everyone, I'm trying to run this example provided by Semtech https://os.mbed.com/teams/Semtech/code/LoRaWAN-demo-76/ with a Nucleo L152RE board and the RFM9X from Adafruit, everything compiles fine but it doesn't work as intended. The program is supposed to send every 5 seconds but I'm receiving messages at random intervals and the device doesn't seem to fill the AppData frame properly, it just fills it with "0". I modified the frame to send "hola" but the random time intervals for each message persist. I'm using Mosquitto for the Gateway, I'm also new to LoRa and I don't know if I have to make additional configuration for it to work properly, it worked fine with a mDot example though.

This is what I got today when subscribing to the lora topic with the gateway
