Fatal error: BLEDevice.h: No such file or directory when running ESP32 BLE example program

[Lakshana]

Hi! When I was trying to connect ESP32 with Blynk using BLE by running one of the example programs in the name ESP32_BLE.ino it shows an error like

In file included from C:\Users\SATYA\Documents\Arduino\libraries\blynk-library-master\examples\Boards_Bluetooth\ESP32_BLE\ESP32_BLE.ino:31:0:

compilation terminated.

exit status 1
Error compiling for board SparkFun ESP32 Thing.
Kindly help me with this.

NOTE: ESP32 BLE Blynk support is in Beta and appears broken due to recent ESP32 Core changes… so even with library corrections, you may not get anywhere with this anyhow…

[BETA] ESP32 BLE initial support

The ESP32 board is a really promising, amazing piece of hardware! I’ve just added some initial ESP32 BLE support: https://github.com/blynkkk/blynk-library/blob/master/examples/Boards_Bluetooth/ESP32_BLE/ESP32_BLE.ino You can try it out and leave your feedback here. Currently, it’s a bit tricky to get connected, but once it connects, seems to be working really reliably. Important notes You need latest ESP32 Core with BLE library included. Here’s a hint on how to get it. Blynk App can…
