Issue with Direct Downlink Transmission from WM1302 Gateway

Title: Issue with Direct Downlink Transmission from WM1302 Gateway

Hello semtech Community,

I hope this message finds you well. I’m currently working with the WM1302 gateway and attempting to send downlink packets directly to end nodes without using a network server. I’ve encountered an issue where although the data seems to be transmitted from the module, it’s not being received at the node end.


  • Gateway Model: WM1302
  • Issue Summary: Unable to receive downlink messages on end nodes.
  • Scenario: Attempting to bypass the network server for direct downlink transmission.
  • Observations: The code for transmitting data from the gateway appears to be working without errors.


  1. Is it technically feasible to send downlink messages directly from the gateway without using a network server?
  2. Are there specific considerations or configurations that need to be addressed for direct downlink transmission?
  3. Could security concerns be a factor in the lack of reception on the node end?

I appreciate any insights, guidance, or suggestions the community can provide to help resolve this issue. Thank you in advance for your assistance.

Best regards, Stalin T John

I received the data in the gateway (wm1302) after transmitting it from the end node (rak4630).I want to send data back to the end nodes from the gateway; is this possible using Lora wan communication? I have a code for transmitting data over a gateway. Will be attached this to.
