• Hardware model: Wemos D1 mini (wifi)
• Android 9, web blynk.cloud
• Blynk server
• Blynk Library version v1.0.1 (github latest)
I can see timer is working by observing the blinking LED.
However, no messages appear in Serial monitor after Blynk is connected to wifi.
In blynk.cloud I see the metadata is updated, device is marked Online, but no sensor data or events are displayed.
Also without Blynk.begin and Blynk.run sensors work and I can see reports in Serial monitor.
Please help.
