Hello. I’m just testing examples and I’ve encountered some problems.
I use arduino uno and ESP8266-01.
I’ve uploaded the terminal example. Works great. Then I added elements from the Get Data ‘(BLYNK_WRITE(V1))’ and Push Data (Blynk.virtualWrite(V5, millis() / 1000)
with Blynk timer examples. All these elements separatly work well. However, after the merger I can not get a connection with Blynk. (internet works). any help?
and a question. functions such as Blynk.connect or Blynk.syncAll (); can only be called from setup after reset board? or from anywhere after ESP power restore?
Thank you
