System connectivity 

The correlation between the components in terms of the overall device architecture is 
described in the figure below.  

 

 

10.1.2

 

Data flow 

The  S-Patch Ex  device  is used to  collect  ECG  and  HR  data  of the  user via the bio-
processor. Besides, it is also equied an IMU sensor to collect tho motion data which is 
used for the R&D purpose only. The ECG data will be transfer to the BLE processor 
based on UART protocol then it will be encrypted and stored in the external flash by 
SPI protocol. The  collected  data from S-Patch  device  will be transmit  to  the  paired 
mobile device by BLE secure.
