Hello,

I using BLE (Bluetooth Low Energy) and can not send anything alse to APP, just String. What I trying to do is readout serial bits 11111110 and send them as Integer to APP.

Using BLE_server Arduino Example from the Arduino ESP32 library.

Based on Neil Kolban example for IDF: https://github.com/nkolban/ESP32_BLE_Arduino/tree/master/examples
Ported to Arduino ESP32 by Evandro Copercini

Best,
Krystian P.

Thx.

I have not add:

https://dl.espressif.com/dl/package_esp32_index.json
http://arduino.esp8266.com/stable/package_esp8266com_index.json

Not go to >>> Tools >>> Board: >>> Boards Manager... and then to install esp32 by Espressif System packet. T18_3.0 20190410 ESP32-WROVER-B ESPRESSIF

The product seems to be good, but instructions on how to start programming are missing. I found drivers for Window 10, but I don't know how to get the first C / C ++ Code in. Can I program it with Arduino IDE ? How to do it ? No download available.
