Xenon debugging using Particle Debugger; Question about SYSTEM_MODE(MANUAL); RED LED Flashing

Hi all, first time posting. I’m new to this, just got a Particle Debugger and hooked up. Using Xenon (part of a mesh, with Argon as the gateway).

I’ve setup the debugger and followed the tutorials, but I get a flashing RED LED the second time I click Continue (F5).

But If I put on top of the code
I can do debugging successfully (no more flashing RED LED) but now, the Xenon isn’t connected to the Mesh network. – which kinda defeats the purpose of debugging.

How do I get rid of the RED Flashing LED, while debugging and also be connected to the Mesh network?
