ibm bluemix - How do two devices communicate on IBM-Watson platform -

-

on watson mqtt foundation, how publish message 1 device (publish-"iot-2/evt/xxxxxxxxx") device (subscribe-"iot-2/cmd/xxxxxxxx")?

how possible devices' publish , subscribe topics cannot same? possible without first receiving in application , republish 2nd device, or devices can send/receive data to/from application?

is watson implementation or mqtt spec?

devices publish events , subscribe commands. application can send commands device.

a device can not send commands device.
watson iot platform has specific topic strings, refer documentation.

if have device such raspberry pi sending commands, have tried connecting application publish command , have other device connect device subscribe , receive commmand?
