Can I develop a software with MESH network support NUS (1MBPS) and 16 Central links support NUS_c (CODED_PHY) at one time?

Can I develop a software with MESH network support (1MBPS) and 16 Central links (CODED_PHY)?

All my tries is unfortunaly. But I dont give up.

Just guide me please and say is my mission possible?

Hi. 

Maybe you could elaborate a little bit on your application and use case?

Do you want to have a central device, with 16 devices in a connection?
Note that BLE Mesh uses managed flooding, and there are no direct connections. The BLE Mesh specification is based on a previous BLE specification, that doesn't support Long Range (CODED_PHY). But you should be able to change the phy for testing purposes at least. 

If you do want a central device with 16 peripherals connected, you could look at using a star network without including any Mesh. We do support up to 20 concurrent links using our SD, so this should be achievable. You can look at the multilink example in our SDK. 

Br,

I have up to 16 peripheral slave devices that should connect with NUS service to a Central master device. So Central master device should support 16 links NUS_c with coded PHY support. And all This Central master devices should connect to Mesh network with 1MBPS support.

Now I develop 16 Central links with coded PHY and one peripheral link with 1MBPS master device. But now I want to change peripheral link to Mesh network. Because i don't know how to connect all master devices.

[Joakim Jakobsen]

I understand. 

Where exactly are you stuck in development here?

Have you downloaded the nRF5 SDK for Mesh? Are you working with NCS? 
Like I mentioned before; the Mesh spec. is based on an older version of the BLE Spec. so coded phy is not supported.

Does Zephyre Project support multilink NUS_client and NUS_peripheral?

[Joakim Jakobsen]

Yes.
