Thanks for your support.
I have to mention that the MH-10 is currently not connecting with Blynk anymore. It happened yesterday too, but today it connected right away and 15 min later it disconnected after I wrote to the Blynk Community. Is there a problem with the app?
The set up is:
- Arduino Uno
- YwRobot voltage converter
- DSD Tech MH10
- I have also the HC-05 Bluetooth Board (brand new from today) but my Iphone does not seem to connect to it. Would the HC-05 work better? Can it be connected to my Iphone via Blynk app?
- LED light.
- GND to GND
- VCC to 5V
-TXD to D3
-RXD to D2 note* (I have interchanged TXD and RXD but still does not work, and I have used TX-0 and RX-1 pins too but it didn’t work either)
-LED to Pin D13 and GND
// You could use a spare Hardware Serial on boards that have it (like Mega)
SoftwareSerial DebugSerial(2, 3); // RX, TX
#define BLYNK_PRINT DebugSerial
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth = "c1086626xxxxxxxxxxce193ab8675f";
// Debug console
DebugSerial.println("Waiting for connections...");
// Blynk will work through Serial
// Do not read or write this serial manually in your sketch
Looking forward to some answers. Thanks again for the help.
