Multiperipheral with NUS

[franck]

Hello,

I have a product using NUS profile and plan to update it to support connection from multiple phone  

Do you recommend to start from Multiperipheral example and import NUS peripheral code or to do the opposite ?

Is there a big impact in RAM use or CPU load high when adding multiple concurrent connection for maintaining the connection ?

Does packet loss and retries on one connection can lead to disconnection on other connections due to lack of time for handling the other connections ?

What is recommended value for BLE_GAP_ROLE_COUNT_COMBINED_MAX ? 

Thanks

Hi.

 I would start from the Multiperipheral example, much easier to import the NUS peripheral code then doing the opposite.

Is there a big impact in RAM use or CPU load high when adding multiple concurrent connection for maintaining the connection ?

 It will double, triple, and so on.

Does packet loss and retries on one connection can lead to disconnection on other connections due to lack of time for handling the other connections ?

 No, this is handled by the central, in the sdk_config.h for your central.

What is recommended value for BLE_GAP_ROLE_COUNT_COMBINED_MAX ? 

 I would not go higher then 20, which is the defined value in SDK 15.2.

Best regards,

Andreas
