Hi,
I’ve got some problems in receive downlink messages from the ttn application console.
My node is in ABP mode and the tx works fine, but when I send a downlink message the node doesn’t receive it. I know that I have to send an uplink in order to receive a downlink, but it doesn’t work.
I can see in both appplication data and gateway traffic that the downlink is sent, but the node doesn’t receive it.
Do I have to set a specific value for rx delay windows, dr, and freq.?
You’re going to have to be a lot more specific about the node.
“AT commands” suggests you have a distinct module running the LoRaWAN stack interfaced to some other processor. Which module is it?
Also your downlink seems to be sent using RX2 using the TTN-EU customized RX2 setting of SF9, rather than the LoRaWAN standard of SF12. With an ABP node you may need to configure this RX2 customization manually. That said, you may also at times see TTN transmit in RX1 (for EU, that would be downlink frequency matching uplink) - it can effectively make its own random choice between the two.
Solved. It was due to a wrong appeui
