Blynk app on iphon12 is Version 3.2.3(1)
Blynk library in sketch is Blynk by Volodymry Shymanskyy Ver 1.0.0-beta3
Arduino IDE installation is 1.8.15 (Windows Store 188.8.131.52)
Board is ESFP32 DEVKI TV1 (on the board chip is says “ESP-WROOM-32”
Amazon.com description for board is “Xiuxin ESP32 Development Board 2.4GHz Dual Mode Wifi Bluetooth Dual Cores ESP32s Antenna Module Board”
Only on selecting the board ESP32 Dev Module does it show the partition info. I’ve tried the “Default 4MB with spiffs (1.2MB APP / 1.5 MB SPIFFS)”, and “Default 4MB with ffat(1.2MB APP / 1.5MB FATFS)”
Message on Amazon.com from the seller (Xiuxin) says to use the NodeMCU 32s board. That’s the first one I tried.
I’ve tried selecting the following boards from Arduino IDE: NodeMCU 32s, ESP 32 Dev Module, ESP32 Wrover, Node32s, FireBeetle-ESP32
On each of the boards I’ve tried, the sketch compiles and loads without problem. It says on the Blynk app on my phone "Blynk Want to Join Wi-Fi Network “Blynk LED Blink - 2FB0F”, I click the “JOIN” button on the app, then the screen says, “Getting Device Information”, then “Can’t connect to the device”.
I’ve even gone into the iPhone WiFi settings and selected the ESP32 as the WiFi provider and it connects without problem. Then I go back into the Blynk App, and it will say to choose the “Already Connected” selection, which I do. But then it gives the same message, “Can’t connect to the device”
