BLE_SPI

• UART + BLE + FDS

  • can capture 2043 data points and write them to flash and transfer to BLE
  • uses FDS library , UART , and SPI together
  • need to include timer() events to control the flow
  • debugging to increase the flash storage size and use timers

• UART

  • can send sensor data through BLE using BLE UART example
  • slow, as the data is being captured and sent at the same time
  • no flash

• LIS3DH

  • contains .h and .c files for the sensor LIS3DH

SPI_LIS3DH

• can print X Y Z values in Log at set sampling rate
• no way to know the current sampling rate
• add file saving option to this

BLE

• can send simple data to BLE
• only allows to write one byte of data at a time
• difficult to merge them together later
