Linux App - Network Analizer and communication from the app to the tags

I am wondering if there is any example of the code for the gateway. I am trying to use a bridge to detect when a tag enters the network and report the location if available and the distances to the anchors. However, while following the examples, I can’t get any data from the network through the bridge node. Even the anchor list command will return an error.

Also, is there somewhere any documentation (sequence diagrams, examples, tutorials… )about how to send user data from a bridge to a tag and vise versa. I am trying to send some data to the Tag as soon as it is in the desired area.

thanks in advance
