The purpose of this project is to develop a firmware for nrf52840 DK and nrf52840 dongle, able to perform the following tasks:
• Connect nrf52840 dongle with mpu9250 (accelerometer)
• Nrf52840 dongle has to be in the sleep mode at the beginning of the cycle;
• Nrf52840 dongle has to be waked up by an external action
• Nrf52840 dongle must read vibration data from 3 axis for 500ms
• Nrf52840 dongle has to calculate the vibration RMS for each axis (the code to calculate RMS will be provided by us)
• Nrf52840 dongle has to send this data to other nrf52840 DK
• Nrf52840 must send this data via UART to computer
• After sending data, nrf52840 dongle must sleep again
