Send more than 4 uplink

Devices

I use the Arduino Uno R3 as a node and the RAK 7248C as a gateway.
The node is configured using Arduino.
The RAK 7248C gateway runs on the Raspberry Pi operating system.
The node sends 5 uplinks and receives 4 downlinks.
I am using the EU868 frequency band.

Can you guide me on how to modify the node or gateway to allow the node to send more uplinks?

You need to make code changes to the software inside the node. There is nothing in LoRaWAN that prevents you from sending more uplinks, as long as you comply with your RF regulations.

Thank you for your response.

I am using the original code from the MCCI LoRaWAN LMIC library without making any changes. I only entered the MAC addresses of the gateway and nodes.
