Relaying data from one Notecard to another

[draeman]

I have an application where I’d like to use Blues ecosystem to exchange messages between devices that have cellular Notecards attached. I understand that Notecards cannot directly address each other. Can I accomplish this by routing/proxying through Notehub.io without the use of other third-party cloud services? In other words, what’s the minimal Blues solution for getting a message from one Notecard-equipped host to another? These embedded hosts do not have Internet access - they only have the cellular Notecards for connectivity. I could even make do with pre-assigned static routes between Notecards. Thanks!

Hi @draeman,

This is a non-uncommon request and there is a little more background in this older thread:

Can I send a message from one Notecard to another Notecard?

@lorenberg Continuing the discussion from Notecard Note-WBEX-500 + Notecarrier AA: cannot connect to cellular network (green led flashes once): we envision a direct communication between a notecard and another, in a peer-to-peer fashion…so essentially we would not probably need the notehub. Is this something we can do with the notecards, or they are just meant for collecting data on the field and sending them on the notehub? No direct Peer to Peer connections between Notecards For security …

Thanks for the reply Rob! I had found that thread, but figured my use case was a little different because I’m willing to route through Notehub. It sounds like use of a third-party solution is still needed to host a bit of glue logic.

It’s almost possible to do something natively within Notehub using web requests along with a route that invokes Notehub API calls. However, it doesn’t quite work because the bearer token needs to be managed.
