Detailed Description

Stateful decoder.

Feed BLE GATT notification bytes via decode(); each decoded MIDI message arrives on the registered callback with a millisecond timestamp reconstructed from the BLE packet header.

MessageCallback

using pulp::midi::BleMidiPacketDecoder::MessageCallback

Initial value:

 
        std::function<void(const std::vector<uint8_t>& bytes,
                           uint32_t timestamp_ms)>

Member Function Documentation

decode()

bool pulp::midi::BleMidiPacketDecoder::decode	(	const uint8_t *	data,
		std::size_t	size )

Feed one notification packet.

Returns true if the packet was well-formed (header + at least one timestamp byte + status). Malformed packets are dropped to satisfy spec section 3 — the decoder does not throw and recovers on the next packet.

reset()

void pulp::midi::BleMidiPacketDecoder::reset

(

)

Reset running status + the in-flight sysex buffer.

Call after a disconnect or when the host knows the stream has been interrupted (e.g. OS sleep/wake).

set_message_callback()

void pulp::midi::BleMidiPacketDecoder::set_message_callback ( MessageCallback cb )
