Issue with ESP32 Library installation in Arduino IDE

[kotteswaran P]

Hi All,
Am using ESP32 devkit V4 for our project to interface it with the MSP430 controller. Can we interface it with the MSP430?
To check the ESP32 Wi-Fi/Bluetooth functionality and to configure, using Arduino IDE.
But facing an issue in downloading the ESP32 Library in Arduino IDE (v1.8.15) using Github URL ( https://dl.espressif.com/dl/package_esp32_index.json ), I added the URL under File->Preferences->additional board manager and under tool->Boards->Boards Manager, I can't find the ESP32 Lib as getting an error ( Error downloading https://downloads.arduino.cc/packages/p ... index.json ) in downloading it.
Please help resolve this issue and also direct me if there is any other way to configure the ESP32.
What is the use of ESP IDF? Is it similar to build the project as in Arduino IDE?

The json is now hosted on github rather than espressif.com

ESP_IDF is the C framework upon which the Arduino HAL is layered. If that makes no sense to you, then you don't need it.

Thanks for the reply @lbernstone, still getting an error while downloading that lib (from the link you shared).

Hi,
Is there any tool or GUI to configure the ESP32 devkit?.
If a person has coding knowledge, they can use Arduino IDE or ESP-IDF to configure. But for those who don't have coding knowledge, is there any manufacturing UI to configure ESP32 in Wi-Fi and Bluetooth mode.
For evaluating the ESP32, we may use the RF test tool right? and In the RF test tool, there is a Wi-Fi adaptivity option to set Wi-Fi in AP and STA mode, similarly to configure it in Bluetooth and BLE mode is there any option?.
For the RF test tool, is there any user guide available?. Like how to evaluate the test parameters and how to use the tool?
Can anyone explain the technical difference between Bluetooth Classic and Bluetooth Smart (BLE)? and how to choose between them?

Thanks.
