Configuration

Check the Configuration! page earlier to set up the sketch for Software/Hardware UART or Software/Hardware SPI.

The default is hardware SPI

If Using Hardware or Software UART

This tutorial does not need to use the MODE pin, make sure you have the mode switch in CMD mode if you do not

configure & connect a MODE pin

This demo uses some long data transfer strings, so we recommend defining and connecting both CTS and RTS to pins,

even if you are using hardware serial.

If you are using a Flora or just dont want to connect CTS or RTS, set the pin #define's to -1 and Don't forget to also

connect the CTS pin on the Bluefruit to ground! (The Flora has this already done)

If you are using RTS and CTS, you can remove this line below, which will slow down the data transmission
