[ABG]

This is an example of scanning for and connecting to 2 BLE devices:

BLE ESP32. Bluetooth. Send. Receive. Arduino IDE. Multitouch

15.- Two ESP32 with BLE send random temperature and humidity by Notification. Common Slider. [esp32_ble28] ESP32 with BLE generates (at random times) two random numbers temperatureBLE1 and humidityBLE2, and notifies them to the application. Another ESP32 with BLE generates (at random times) two random numbers temperatureBLE2 and humidityBLE2, and notifies them to the application. App sends a value to the two ESP32s through a Slider. [esp32_ble25] - Code for ESP32 with BLE1: // Juan A. V…

Note that the NAME is not needed, and probably adds a complication.
