Hello,
My configuration is :
Uno ,hc05,blynk,android gsm.
The gsm screen stop display entering data from uno after some time.
Going in the program window and out restart display fonction.
Thanks for some help to put my out of this rut.
Need a bit more info, what are you reading? What program screen?
But, with Blynk servers there is a maximum operations per minute to stop server flooding, maybe they are disconnecting you?
Further info:
Maybe post your code?
