Partial reconnection with Blynk after disconnection of WiFi

I also initially coded without any provisioning and hard coded the credentials of wifi through code. But the thing is that it does not make my IR remote work properly when my there is no internet and it also fails to make connection with blynk after wifi gets turned on

In that case you probably used Blynk.begin() which is a blocking function, so all code execution will stop at that point if the sketch can’t connect to either WiFi or the Blynk server.

For a non-Blocking Blynk connection you need to use Blynk.config() and Blynk.connect(), manage your WiFi connection manually, and have a re-connection routine for both WiFi and Blynk. Here’s an example…

BLYNK.connect() timeout event syntax

I think the bug is actually in your code, and the way that you’re using flags instead of simply doing the WiFi and Blynk connected tests each time they are needed. You’ll see three places where there is a comment that says “Commented-out for testing”. These if statements that are commented-out would normally prevent the sketch from attempting to connect to Blynk is there is no WiFi connection, but to prove that the Blynk.connect(timeout) functionality works correctly, we need toa allow the ske…

So i changes it to static provisioning

I think you mean “so I changed to dynamic provisioning using Edgent”

@BeamCruzer

If you know a better way to do it without any provisioning

As I explained earlier, you have to provision your device with the WiFi credentials and Blynk Auth token, otherwise it can’t authenticate to these systems. You should be looking at static provisioning, where these credentials are hard-coded into your sketch, rather than the complexity of dynamic provisioning via Edgent.
