I have tried all sorts of ways to get blynk to run on bluz but no luck. If I search in the particle web IDE for blynk and select the 03-bluz-direct example to load. When I go to verify it always errors out. It says BlynkSimpleSerialBLE.h no such file found. If I comment out the line then it says blynk.h not found.
We currently do not have support for blynk, but it is something we are actively working on, so please stay tuned and we should hopefully support this soon.
