Stop ble_app_uart connection with ble_app_uart_c

[Kaveh.M]

I am using: \examples\ble_peripheral\ble_app_uart  and  \examples\ble_central\ble_app_uart_c  .

In Nordic infocenter it says: The application scans peripheral devices and connects to a device that advertises with the NUS UUID in its advertisement report.

The questions are: 

1- Is this type of connection similar to a pairing where a key exchange occurs and connection is encrypted between peripheral and central?

2- How can I modify \examples\ble_peripheral\ble_app_uart code to drop the connection and reconnect periodically (for power saving) .

Hi,

The UART driver is returning invalid state because you are application is trying to initialize the same UARTE instance twice, once by the logger module, and the other by the application (uart_init() in main). The solution is to only use RTT for logging and disable the UART logger backend by setting NRF_LOG_BACKEND_UART_ENABLED to '0' in sdk_config.h

Thanks Vidar. That fixed the problem and it is now working.
