First Byte 0x11 is the length (17 Bytes, excluding the length byte).Below is an example for a typical scan response packet that contains the service UUID alone:Ġx11 0x07 0x00 0xC7 0xC4 0x4E 0圎3 0圆C 0x51 0xA7 0x33 0x4B 0圎8 0圎D 0x5A 0x0E 0xB8 0x03 (Totally 18 Bytes).Either the advertisement packet or scan response packet should contain the UUID of the MIDI Service in the Service UUID field.The BLE Protocol can be used to implement the MIDI standards, enabling a connection between BLE enabled musical instruments and other devices such as Phones, computers, speakers etc., A BLE MIDI Controller should meet the following standards: The MIDI (Musical Instrument Digital Interface) protocol is a standard that defines the way various devices transfer music related audio data. Related Hardware: CYW920719Q40EVB_01 Board Block Diagram Tool: WICED Studio 6.1 and above, Any MIDI Central Client (Example: Garageband App for iOS), Serial Terminal (Example: TeraTerm, CoolTerm). The CYW20719 maps the ASCII inputs from the PUART to MIDI notes and sends them as BLE notification to a MIDI Central in accordance with the BLE MIDI Specification. The CYW920719Q40EVB_01 Eval board is connected to a PC and keypress from the keyboard is sent as input to the PUART terminal of the CYW20719 device via Serial COM terminal interface of the Eval board. In this example, the CYW20719 device is configured as a MIDI Server that sends MIDI data over BLE.
