Xenon based Mesh network only

If you still have that simple Xenon+Ethernet/Xenon/Xenon setup around: Could you do the same test except turn off all the devices and just bring up the Xenons and see if they can still get organized with each other without the Xenon+Ethernet gateway?

@rickkas7

SYSTEM_THREAD(ENABLED);

the example above will work if you power on the Xenons without a gateway. They’ll communicate between each other just fine. You could probably also use SYSTEM_MODE(SEMI_AUTOMATIC) and only bring up mesh using Mesh.connect() as well.

I am very interested in this ability as I am getting good results with 3 Xenons when setup with an Argon but then turning the Argon off.

Mesh Hello World

Try this code when you finally get your Mesh Argon working with a few Xenons. Just change the number for each Mesh Device. I use 1 for the Argon and comment out the particle.publish line for the Xenons. IMPORTANT: This code has been updated to make the Particle Featherwing Plug and Play Also now includes an Antenna for both the Xenon and the Argon See High School Robotics Course using the Particle.io Mesh Devices Blog for distance testing. // next 2 lines are for plug and play particle feat…

Using SYSTEM_THREAD(ENABLED); will that dramatically effect using the Argon? I would like both abilities. Works fine with the Argon can flash Xenons etc, but when the Argon is off the Xenons work fine locally. Any suggestions. I think I will just insert the code above and see what happens.

....

So I tried

SYSTEM_THREAD(ENABLED);

which did not seem to let a Xenon connect to working Xenons without a gateway. Note: for me once running with a gateway my Xenons are reasonably stable once the gateway has been turned off.

Xenons can be reset, but cannot power down and reconnect to the local mesh. Using threaded seems to offset the timing a bit. before all local devices blinked at exactly the same time, not using threaded they are offset a few microseconds

Will try

SYSTEM_MODE(SEMI_AUTOMATIC)

but I need to be able to connect to an Argon if it is available. Might try a 60 second delay to connect on boot.

A little scared to run this code in my setup using SYSTEM_MODE(SEMI_AUTOMATIC)

   Mesh.connect();
   delay(60000);
   if (! Mesh.ready()){
       Mesh.disconnect();
   }

@rickkas7 any suggestions for code to try to allow the Xenons to wake without a gateway.
