Hi newbie here. I’m currently (slowly) learning my self into Blynk, C++, ESP’s and Arduino’s. I’m currently working on a bridge between two ESP’s using this topic. One of the thing I noticed is that this person does:
Now both are connected to the same Blynk app. This raises a couple of questions:
- why is he using ‘1000’ and is this the same as ‘HIGH’ ??
- are the Virtual pins unique for each device (as this code presumes) or will this run into potential errors? Basically he write ‘1000’ to V5 on ESP2 and h (humidity) to V5 on ESP1. I was under the impression that the VP’s were stored on the Blynk server and the same for one application (apparently a wrong assumption, but I want to check).
- how many VP’s are there actually?
- He doesn’t set:
in the void setup(). Is this not required for Blynk?
