Hello all,
I currently have a simple project to connect Blynk Android app to an Arduino Uno via GPRS. I receive GPRS connected but then connecting to blynk-cloud.com:80 login timeout continuously. I have uploaded an image of the serial monitor too.
Here are the details:
• Arduino Uno with SIM808
• Android Samsung S9 - Andriod Version 10
• Blynk-cloud.com:80
•Using Arduino library Blynk 0.6.1. Using Blynk example code "TinyGSM_SIM800_SIM900
• Sketch code below
/**************************************************************
*
* For this example, you need to install Blynk library:
* https://github.com/blynkkk/blynk-library/releases/latest
*
* TinyGSM Getting Started guide:
* https://tiny.cc/tinygsm-readme
*
**************************************************************
*
* Blynk is a platform with iOS and Android apps to control
* Arduino, Raspberry Pi and the likes over the Internet.
* You can easily build graphic interfaces for all your
* projects by simply dragging and dropping widgets.
*
* Blynk supports many development boards with WiFi, Ethernet,
* GSM, Bluetooth, BLE, USB/Serial connection methods.
* See more in Blynk library examples and community forum.
*
* http://www.blynk.io/
*
* Change GPRS apm, user, pass, and Blynk auth token to run :)
