WAZIUP - Open Innovation Platform for IoT Big data in Sub Sahara
Co-funded by the Horizon 2020 Framework Programme of the European Union
Sometimes the world turns up true gentlemen (and ladies of course) helpful people like @BoRRoZ, @Charles and this guy too, G6EJD who publishes ESP stuff on his channel on YouTube.
I casually asked him if he thought it would be possible for a super low powered, LoRaWAN connected semi smart signage solution to leverage the power of a person’s phone by writing a QR code to an ePaper display. I have this in the tech specification of a proposal I have written but had no idea how to do it. The important word in that sentence was “if” but he went the whole way and published a tutorial on “how”.
The concept is that URL’s can be called from memory or even sent to a remote low powered node which can create and write QR codes and then sleep. What a helpful guy, looks like this is staying in my specification now!
release note for release A1-0-17
This release will be deployed on Wednesday June 27th 2018 at 10:00 CEST.
No breaking changes but we added V2 endpoints on location & recipes queries to make them more consistent, and allow a single query to be send to any endpoint with the same JSON structure.
It should be a big step forward to your software simplification.
We will maintain the V1 API but we encourage you to switch to V2, as we still are in private preview we might stop them soon.
