Hi, I have problems with nodemcu, as soon as I enter the Blynk.syncAll () command; the device disconnects and reconnects from the blynk server, but all this does not happen on me always with an identical code, I have tried more than one nodemcu but I always have the same problem someone has had the same problem? Thank you.
