Hello RAK Wireless Community,
I am experiencing an issue with both the RAK11720 and the RAK3172 modules. While the AT commands are responding correctly, neither module is able to establish communication with the LoRaWAN network server. Interestingly, the same Arduino code works flawlessly on the RAK4630 using the same gateway and network parameters. I have some hardware with RN2903 and the communication is working well.
Here are some details regarding my setup and the troubleshooting steps I’ve taken so far:
Modules:
RAK11720 (using RUI3 interface)
RAK3172 (also using RUI3 interface)
RAK4630 (for comparison)
AT Commands:** Both the RAK11720 and RAK3172 respond properly to AT commands.
- Code: I am using an Arduino ABP example that works without issues on the RAK4630.
- Gateway & Network Parameters: The gateway configuration and LoRaWAN parameters (DevEUI, AppEUI, AppKey, frequency plan, etc.) have been verified and are identical for all modules.
- Troubleshooting Steps Taken:
- Confirmed that the modules are running the appropriate firmware versions and have been reset to factory settings.
- Monitored AT command logs during the join process to look for discrepancies.
- Verified UART configurations and physical connections for all modules.
- Compared the initialization sequences, considering all modules are using the RUI3 interface.
Despite these efforts, the RAK11720 and RAK3172 still fail to join the LoRaWAN network, while the RAK4630 performs as expected.
I would greatly appreciate any guidance, suggestions, or insights from the community or RAK Wireless support to help resolve this issue.
Thank you for your time and assistance.
Best regards,
