Sending data over NRF24L01 to RPi

I'm working on a datalogger that I want to send its data to a Raspberry Pi and be written to a MySQL database.

What is the best format to send over the data? I have maybe 6 or 7 parameters that I need to send. Do I send them one at a time? Or can I send them comma separated?

What is going to be best when it comes to receiving it on the Pi, parsing the data, and writing it to DB?

Any tips are appreciated.

Buffer can be 32 bytes, so you can transfer all readings to the transmit buffer. Receiving uC can assemble bytes before storing.
