Ble ECG program and configuration using nrf52832

[isti]

is there a tutorial for Ble ECG program and configuration using nrf52832? I want to make integration from heartbeat sensor to nrf52832, make nrf52832 connect to computer using Bluetooth and make simulation using Matlab and get signal ECG

I want to get ECG and pass that data from nrf52832 to Matlab first. Is it your mean just pass the raw ECG data using blue apps UART ? and how can I configure the data rate?
