Documentation on how to send&recieve a single datum struct object (via serial) that exceeds the 254-byte maximum packet size

Is your feature request related to a problem? Please describe.
The examples all presume an object is under the 254-byte limit.

Describe the solution you'd like
An example.

Describe alternatives you've considered
I have tried to adapt the code in the 'uart_tx_file' & 'uart_rx_file' examples, but cannot seem to figure out how to recombine the chunks

Additional context
I have a struct that contains 94 float values and (obviously) only the first 63 make it through. Unfortunately, I cannot debug via the serial port as I'm using a single board with both an AT328 & ESP8266 and they connect via the hardware serial port, so I have either a serial connection to monitor, or a connection between the two chips - never both, making this very hard to diagnose. Any help would be appreciated.

Thank you!
