UART BLE application for nRF52 and nRF52840

[Sudheer]

Hi,

Can you please provide a small UART application for the nRF52 and nRF52840, to communicate with PC application using bluetooth.

The deafult ble_peripheral applications are not working when i compile them using SES. There is a confusion which exmple to use from the Development kist folder, the forders are named s132, s312 and s332 (I am not sure what this folder names refferes to).

These are different versions of the SoftDevice(Bluetooth stack). For the nRF52840, you have 2 options in nRF5 SDK version 16.0, S113 and S140. See this combability matrix. For nRF52840 you have a lot of available flash and ram, so I recommend using S140, since it has more features than the S113. So for nRF52840, you should use the SES project in SDK_folder\examples\ble_peripheral\ble_app_uart\pca10056\s140\ses

I want to implemetent my own protocol packets. Which file or function I can reffer to change the protocol.
