Plotting analog sinal

by robin1117 on Fri Apr 21, 2017 1:48 am

I bought Bluefruit LE SPI Friend and nRF8001 to send EEG data to iPhone through bluetooth. Is there any arduino source code for using Plotter in Bluefruit app?

Start with something like the bleuart_cmdmode example code and ensure you are able to connect and send text to the BLE App.

The trick to sending data to the Adafruit BLE App in Plotter mode is to ensure that the data is followed by a newline character. Do this:

ble.print("AT+BLEUARTTX=");
ble.print(data);
ble.print("\\n\n");
