Datasheet

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
// this line is particularly required for Flora, but is a good idea
// anyways for the super long lines ahead!
ble.setInterCharWriteDelay(5); // 5 ms
Running the Sketch
Once you upload the sketch to your board (via the arrow-shaped upload icon), and the upload process has finished, open up the Serial Monitor
via Tools > Serial Monitor, and make sure that the baud rate in the lower right-hand corner is set to 115200:
