Hello @modaltb @Eric-Katzfey @Alex-Kushleyev 
I am trying to send a trigger message from voxl-tflite server to voxl-mapper server. 
Once the object is detected an trigger message will be received and identified by the voxl-mapper and a custom marker will be placed in the position. 
1. I would like to know how to send a trigger and how to accept the incoming data in voxl-mapper.
2. Also where to place the custom marker code, so that it will be mirrored in the 3-D map in the portal.

thank you
