Here is my configuration:
- Raspberry Pi Zero W with private Blynk Cloud in my WLAN.
- One DFPlayer with NodeMcu with Blynk App with this software
- Second DFPlayer with NodeMcu with Blynk App with this software
- Third DFPlayer with NodeMcu with Blynk App with this software
Numer “One”, “Second” and “Third” are customized in the same Blynk App ( + New Poject)
Some other ESP8266 (NodeMcu) for on / off LEDS in the same Blynk App are working fine.
The number “One” DFPlayer works fine with no problems. The “Second” and “Third” DFPlayer did not work every time. I can see number “One” and “Second” in the Arduino IDE Serial Monitor.
All three ESP8266 (NodeMcu) works with the same virtual pine VPIN_PLAYTRACK V4, VPIN_MUSICPLAYER V5, VPIN_VOLUME V6 and VPIN_EQUALIZER V7. Every ESP8266 has its own “char auth”. I have changed the ESP8266 and the DFPlayer.
Does anyone has an idea why the number “Second” and “Third” did not work?
Here you will find the code:
