Hello,
I’m looking at what would be the best way to get bidirectional comms happening on a spark core.
What have people used?
What would you recommend?
@Gizmo, between a Spark and what else? Is there a master/slave relationship? What type of data needs to be transported? Do you need stateless communications or a full protocol?

@Gizmo Also what type of communication do you want? Wired, I2C, SPI, … Wireless (TCP/IP, UDP, Spark Variables, …) Then there are the other options of attaching another device 433Mhz, Bluetooth LE, …
There are a TON of options.

@Gizmo, one very good option for M2M is to use MQTT. There is already a library ported for the Spark and topics in the Community you can search like this one:

Hello,
Yeah like MQTT. I read that post.
Just wondering if anyone else is using anything else.
As longs as the comms are bi directional and get around things like NAT, I’m keen to hear.
Obviously the more “plumbing work” that been done the better.
