uart service security problem

[yiran]

I found in ble_app_uart example, any device with UART app can connect to uart service and send something to COM port or just block the connection of other devices.

So can I take some action to prevent specified devices connecting to my dongle running ble_app_uart？

I believe what you want to do is to use the device manager to bond the device you connect, and then use whitelisting to only allow this device to be connected in the future.

You can read about the device manager here: Device manager

An example that demonstrates bonding and whitelisting is the ble_app_proximity example. This is documented here

Okay, so these nRF51 devices are placed outside somewhere in a public place, where everyone are able to connect to them? I'm not quite sure what the general way to handle this scenario is, but I can ask around and come back to you tomorrow
