Downlink error in v3 UI - message not arriving at gateway nor device

TTN V2 to V3 Upgrade V3 Integrations
30

Hi Nick,

Sorry for the confusion. This is what I did:

  1. I recompiled the device codes which uses the LMIC 3.3.0 lib with DELAY_DNW1 set to 5
  2. Upload the codes to the device.
  3. From TTN console, for this device, I set RX1 Delay to 5

From TTN Live Data page for this device, I can see the Uplink msg.
From Device logs, I can see EV_TXSTART and it paused for 5 seconds.

However, no Downlink reach the Device (nothing showing from device logs).

Is the Rx1 Delay indicate the time in seconds that TTN should send the Downlink after receiving an Uplink msg?

Ok, undestood on no more Confirmed Downlink!
Ok, understood on no need to set u1_t confirmed parameter value to 1.
