Unable to make mesh connection with xenon and argon

I try to create a mesh network using argon and xenon. I config the argon using particle android app, it works fine. Now I try to config xenon and add to the mesh network but the particle app is not finding the mesh network created my argon module. The app keeps on searching the mesh network for a long time

What RGB code does the Argon show during the process?
Can you post a screenshot of your mobile app after aprox. 1 minute of searching for the mesh network and a photo (short video) of the two devices with their RGB leds showing their respective states?
