Issue with Uplink Transmission Limitation on a LoRaWAN Network Using Arduino Uno R3 and RAK7248c

[tarq2000]

I am currently developing a LoRaWAN network and have encountered a recurring issue that affects the uplink communication from my node, an Arduino Uno R3, to my gateway, a RAK7248c, with ChirpStack serving as the network server integrated within the gateway.

Problem Description: After initiating the network, the node is able to send only five uplink messages successfully. Following these transmissions, the network server ceases to respond with downlinks, and no further uplinks are processed. This behavior persists despite multiple attempts to reset and reconfigure the system.

Configuration Details:

Node Device: Arduino Uno R3
Gateway: RAK7248c
Network Server: ChirpStack integrated on the gateway
Frequency Plan: [Specify frequency plan, e.g., EU868]

I am seeking insights or potential solutions that might explain the limitation to five uplink messages and the lack of subsequent downlink responses.
Any suggestions or diagnostic tips from experts in the community would be greatly appreciated.
