Not quite sure if this is an issue with the library or the RTP protocol. But I'm using MIDI as the transport protocol for configuration data for some devices, and the JSON data is serialised with ArduinoJSON, which because of the size of the data, parses out chunks of the data rather than a completed array. Therefor when sending via SysEx MIDI, it sends partial packets, only with the F0 and F7 framing bytes for the complete packet, not each chunk.

This approach avoids extra overhead and complexity of having to add the framing into every transfer (often 10K+ bytes in size). For other transports such as USB device, Serial, BLE, this is working well, but it seems that packets which are not fully framed are not sent via RTP. Could you advise if this is an underlying limitation of RTP which I will need to work around (incomplete packets not possible, and I will need to change my approach), or a library parsing limitation (which could be fixed in the library parsing)?
