Hello Community,
I’m experiencing a critical issue with downlink transmission in a RAK Wireless mesh gateway deployment running ChirpStack Gateway OS and would appreciate your technical insights.
Gateway Models:
- Border Gateway: RAK7289CV2
- Relay Gateway: RAK7289V2
- Deployment Type: Mesh network with one Border Gateway and one Relay Gateway
- Distance Between Gateways: 5 meters (test environment)
- LNS: ChirpStack v4.11
- Uplink Status: Working correctly through mesh network
Primary Issue – Downlink Failure
When initiating manual downlinks from ChirpStack LNS:
- Border gateway receives and forwards the downlink
- Relay gateway fails to transmit it
- Logs return:
Handle mesh event error: TX Ack error: TOO_EARLY
