Hi Vidar,

I have send you some repplies. I try to summarize here. I have the ble_aggregator for SDK 17.1.0 you sent me, but modified including NUS service. I attach it here.

devzone.nordicsemi.com/.../ble_5F00_aggregator_5F00_NUS.zip

Is it possible to send UART messages by NUS service from the aggregator to all the NUS devices connected. And I can receive message from any NUS device and read it in the UART of this aggregator.

Thank you for your support.

Regards,

Joel

Hi Vidar,

I have now the multi-link-multi-role application able to aggregat multiple devices running ble_app_blinky or ble_app_uart with NUS services. However, I cannot only exchange data through terminal connection between the central multi-link board and one of the NUS devices. I have to modify the program as to select the NUS device to which connect selectively. Please, any suggestion?

Thank you in advance.

Regards,

Joel

Hi Vidar,

I would say that the NUS service was not completely introduced. I think there's more job to do to discriminate the type of devices connected and introduce the necessary ble_nus_xxx functions and management of the events and handles.

Hi Vidar,

Thank you again.

I have tested up to 3 nRF52840-DK boards using the ble_app_blinky example. They work after configuring correlated device names. I have also tested using the BLE Multi Link Demo phone app with an older Android version (it doesn't work with some new versions).

My next step is testing the multi-link-role solution using the NUS service with these same 3 nRF52840-DK boards as NUS peripherals. According to the information I have found it's suppodes this should work. Although I have seen in the code that it will be necessary to enable the different define in the sdk_config.h file. Do yo have any other suggestion? Thank you in advance.

Best Regards,

Joel

Hello Joel,

I ported the aggregator project to nRF5 SDK 17.1.0, please see attached. You can see the changes I made in the included port_sdk17.diff file. I expect it should work, but I have not tested it with multiple nodes.

Hi Vidar,

What are the main differences and issues I should consider to make the porting to nRF5 SDK 17.1.0?

Or is there any other multi-link and multi-role example in nRF5 SDK 17.1.0 with the same functionalities?

Regards,

Joel

Hello Joel,

This example requires nRF5 SDK 15.2.0 to build. It has not been ported to SDK 17.1.0.
