Hello,
I’m having issues with time synchronization when using the sidewalk Sub-GHz template from SDK v2.5.0. My setup includes a Nordic Semiconductor chip nrf52840 and LR1110 running on an amazon sidewalk dev kit wm11110-A, with an Amazon Echo device acting as the gateway. I’m located in the Netherlands and have configured my router with a VPN connection to the United States.
The BLE example from the same SDK works with this setup, but with the Sub-GHz template, time synchronization consistently fails. I have followed the default template settings with instructions from https://github.com/Lora-net/SWDR006 and used Lora. I’ve confirmed the VPN connection is active during tests and that the gateway is operational, as shown by the BLE example functioning correctly. However, Sub-GHz communication seems to initialize but fails during the synchronization process. Could this issue be related to additional Sub-GHz configurations I might be missing, or could the VPN or geographical location impact time sync for Sub-GHz? Are there any additional logs or diagnostics I should check to better identify the root cause? Any guidance would be greatly appreciated!
