Hi all  
I found and verified the operation of a library to create a gateway with Raspberry PI3 and Dragino Hat v1.4, which allows the downstream messages

I used the code [https://github.com/bokse001/dual\_chan\_pkt\_fwd/tree/dual\_chan\_pkt\_fwd\_up\_down](https://github.com/bokse001/dual_chan_pkt_fwd/tree/dual_chan_pkt_fwd_up_down)  
following the directions with the changes written in the post1  
[DRAGINO problems and solutions topic](https://www.thethingsnetwork.org/forum/t/dragino-problems-and-solutions-topic/8951/13)  
and in the post2  
[DRAGINO problems and solutions topic](https://www.thethingsnetwork.org/forum/t/dragino-problems-and-solutions-topic/8951/66)

@BoRRoZ do you suggest making a dedicated topic ?
