DOWINLINK data is not received.

I have a NUCLEO-L152RE and SX1276MB1LAS. And I am running lora_pkt_fwd in Linux environment.

I am testing ClassA with LoRaMac-node, but data of DOWNLINK is not received. The current version is v4.4.2.

Build

cmake is shown below.

UPLINK Test

Run the board and i will see the message 'UPLINK FRAME #XX' in SX1276MB1LAS. It then sends data from the packet_forwarder on Linux to the TTN. Data is well received through TTN's Gateway and Applications consoles.

TTN Gateway console

TTN Applications console

UPLINK works well. However, DOWNLINK data sent from TTN's Applications console is not received through LoRaMac-node. Data is checked up to lora_pkt_fwd. However, there is no log related to DOWNLINK in the logs of LoRaMac-node.

NUCLEO-L152RE

There is no log related to DOWNLINK anywhere.

Version used LoRaMac-node: v4.4.2 lora_gateway: v5.0.1 packey_forwarder: v4.0.1

Is there anything else I need to do to receive DOWNLINK data? Or is it a bug in the current release?

I'm sorry I do not have enough English. :) Thank you.
