@ladan.nir I recently provided an up to date template called NoBlynkBlock.ino to bypass Blynk.begin() blocking routine for ESP’s. It’s contained in this thread Blynk is blocking if internet is down but also reproduced below. Basically it gives the ESP a regular WiFi connection and then tries to connect to the Blynk server. You will need to incorporate this into your sketch in place of Blynk.begin(). All tested as working within the last few weeks.
See ESP work offline for latest working template.
