ESP32 Bluetooth Midi (BleMidi) 前回、ESP32を使ったMIDIインターフェースを作りました。 しかし起動時にBleが自動的につながらない・SysExが4000byteリミットなど少々問題がありましたのでその辺を改善しつつ、シンプルなBleMidiを実装しloopバックしたBleMidiの生のコードを見ていこうと思います。

A2: Bonding is not required for BLE communication. If the BLE device can't store the Bond information, it may lead to some issues as we got in our case. If the BLE device is able to store and use Bond information then it's recommended to Bond. A3: The Connection will not be closed. The only downside we got is that now it takes a little more time to reconnect.

Saving bonding data 2. ... 1.0.7 official release that is downloadable from the Arduino IDE ... as this requires low level firmware changes to the Nordic BLE stack. ...
Smart / Bluetooth Low Energy in version 4.0 and 4.1 . In fact, it is estimated that there are over 4 billion Blue-tooth Low Energy (BLE) enabled devices in 2018 (using version 4.0 or 4.1) . In this report, we illustrate the fact that Bluetooth is a widespread technology with real security vulnerabilities
I read on Wikipedia that AES-128 is supported, and chips like the CC2540 provides hardware acceleration, but it's not clear if AES encryption is an option or mandatory by design. IIRC, Bluetooth 2.1 offers a non-secure mode so encryption is only optional, but I wonder if the same applies to BLE.
1. BLE device with only one button and no display - we program this one 2. Smartphone We don't want anyone nearby to be able to pair with the BLE device and then read/write. We only want people with physical access to the device to be able to pair with the device for a short limited amount of time (e.g. X seconds) and then be able to read/write.

- secure pairing and bonding procedures after that. * Bluetooth Classic is the technology The Dash uses for audio transfer (e.g. music and telephony). This is not to be confused with Bluetooth Low Energy (BLE) which is used data exchange, for example during activity tracking. Although they partially share the same name they are different ...
- Bluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances using UHF radio waves in the industrial, scientific and medical radio bands, from 2.402 GHz to 2.480 GHz, and building personal area networks (PANs).

- The module integrates traditional Bluetooth, low-power Bluetooth and Wi-Fi for a wide range of uses: Wi-Fi supports a wide range of communication connections and direct connection to the Internet via a router; Bluetooth allows users to connect to a mobile phone or broadcast BLE Beacon for signal detection.
- Hi everybody, I trying to understand how BLE security works on ESP32 and I saw something strange for me. I am using : Arduino IDE 1.8.8 ESP32 1.0.0 Espressif Systems board library ESP32 BLE Arduino 1.0.1 library by Neil Kolban I downloaded: BLE_server_passkey.ino
