Hi,

Yes, that should work. I can not think of a reason why not. We have code PHY example as https://github.com/nrfconnect/sdk-nrf/tree/main/samples/bluetooth/peripheral_hr_coded and https://github.com/nrfconnect/sdk-nrf/tree/main/samples/bluetooth/central_hr_coded, but without multi-connection.

Hi Amanda!

Is it possible to add the coded PHY feature into the multi-nus? In the end, coded PHY connectable concurrent connections.

Can you please guide me in this regard?

Thanks,

Hi,

That example project is based on NCS v1.4.1. You cannot just download and build it under NCS v2.0.2. I would suggest you use v2.0.2 Bluetooth: Central UART sample, and modify it refer to the tutorial.

Amanda

Hi Amanda Hsieh

I tried to compile the Multi Nus project in Vs code studio. I am using NCS V2.0.2. I got the following errors can you help me in this regard?

Hi,

Have a look at the Enter the Multi NUS a simple wireless UART network article.
