Blynk library version: master branch at 144a90f3bdb66c3b6c03cce0335c1f1e304d91d6
IDE: VS Code + PlatformIO
IDE version: 1.52.1
Board type: ESP8266
Additional modules: Arduino ESP8266

Scenario, steps to reproduce

Blynk.run() blocks if there is no internet connection on the network and connecting to a local server via SSL.
According to my investigation, `BlynkArduinoClientSecure::conn

Problem

The ESP32 example application should be using FreeRTOS tasks(like the EFR32, nRF5 examples) instead of a while loop with a sleep. Because of this it currently needs to poll the buttons to use them.

Proposed Solution

Switch to the AppTask model the other examples use and update the buttons to be interrupt based, if possible.

ENHANCEMENT

1. Describe the enhancement you are requesting.
   Consider using Go errors group (golang.org/x/sync/errgroup) for handling routines in main functions of Mainflux services.

2. Indicate the importance of this enhancement to you (must-have, should-have, nice-to-have).
   This is a nice-to-have.

What would you like to be added:
Add a GetBlockHeightByBlockHash public method in coreService.go
The block height could be accessed through blockDao

height, err := core.dao.GetBlockHeight(hash)

Why is this needed:
replace dao.GetBlockHeight() in grpcserver.go with func in coreService.go
