Delays in LoRa Message Transmission with AVR128DA48 and SX1276 Module for Real-Time Alerts

Hey guys, I’m working on a real-time alert system using LoRa to notify operators when a sensor picks up a problem, like high temperatures. I’m using the AVR128DA48 and the LoRa SX1276 module. This is the code I’ve written for sending a basic alert:

void lora_send_alert() {
    lora_send(lora_dev, "High temperature detected!", sizeof("High temperature detected!"));
}

However, I’ve noticed a significant delay in the message transmission, which really undermines the idea of real-time alerts. I’ve double-checked the module’s configurations, and everything seems to be set up correctly.

Can anyone help me figure out what might be causing this delay in transmission? I’d love to hear any tips on how I can optimize the system for quicker response times using the MC.
