I originally got argon to 2 xenon mesh network communication. Since Particle is going away from using the mesh network and xenons, I’m now trying to take a crack out of argon to argon communication using the BLE mesh library from this link: https://support.particle.io/hc/en-us/articles/360044755894-Create-a-local-publish-subscribe-group-using-BLE-on-Gen3-devices .
I’m trying to do this without connecting to cloud. My application is creating biometric motion sensors using accelerometers. My code is below.

}
}
) to wrap the code block in some better readable form?
