Updated the attached example. Had forgot to add the pstorage handler in the system event dispatcher. Without this the peripheral would fail to restore encryption on following connections. Good work on the multilink example, hopefully it can be of use for others as well.

Hi, I just let you know that I released a modified version of the UART central example that can connect to many peripherals at the same time. You find it here: github.com/.../nrf51_multi_nus_central

Modified the uart peripheral and central example to support bonding and attached it to my answer above. Please check if it gives you the same result.

Are you refeering to the central or client device regarding the Sequrity requirements.

The client device works fine in bonded/encrypted together (with device manager) with a custom app. However when I use the client device with the central example above, the transmission from central to client works fine, but reception from client is ignored. I have enabled ENABLE_DEBUG_LOG_SUPPORT on both, and on the central I only see the "[uart_C]:" events when sending data, but no indication of received data. I do not know if data is actually sent from the client, but I gets not errors from the ble_nus_string_send function.

It works fine with bonding/encryption disabled from the client device. (But when client disconnects the client crashes, but that is a compleate different issue)

Security requirements has to be set in the application and is typically handled by the device manager module /peer manager.

However, the UART example is one of the few examples that doesn't support bonding by default. You may find this tutorial helpful if you want to add the device manager to your project.

Works fine. However it does not work if client device requires encryption. :-( Shouldn't the softdevice handle the encryption requirement automatically, just like the OS on the smartphone?

There is also an example in the nRF5 SDK v11, you can find it at \examples\ble_central\ble_app_uart_c

There is a uart central example based on SDK 9.0.0. available on our github page: https://github.com/NordicSemiconductor/ble_app_uart_c_S120

EDIT 23.2 - Added code example:
