MQTT and functions

[kannnyyy]

Hi shanevanj, Is this possible with two photon devices? I want device to device communication, both devices being able to publish and subscribe to one another, and use subscribe handlers to acquire data.

I have gotten it to work with Particle Cloud - Particle.publish/subscribe, however it is not efficient enough for IOT Blynk applications. You can view my code here for the Particle Cloud application on both devices.

Set subscribe handler data as global

[particleconsole1] Here’s my particle cloud event console. Seems like the LDR Threshold if statement inside the void loop() is not allowing the particle.subscribe(temp) and (pressure) to be read constantly. I will re-write my code, replacing particle.publish/subscribe with MQTT.client publish.subscribe, use softaware timer functions and keep my void loop as clean as possible.
