How to add ble_app_multilink_central with uart service So that one peripheral can communicate with multiple peripheral over central ?

[Jim_huan]

And  base the nus service ,each peripheral   can send message  for cenrtal  to  other   peripheral  like mess.

I doubt it is  possible  because this example is base on the LED Button service ?

Hi Jim, 

 

I don't think it's a mess network here, but rather a star network. All traffic have to go through central node.

 

I don't see any problem implementing a NUS service in this case. Both NUS and LEDButton service are Nordic's proprietary and very similar to each other. Please try to implement the NUS service and let us know if there is any problem. 

The additional feature you need to add is to define a list of "opcode" inside your NUS payload to tell the central node which device it should forward the packet or if it's a broadcast packet. 

 

If you are thinking of a mesh network , what about using our NRFMesh solution ?

you are right,Because implememting a NUS service seen to so difficult for me.

But be aware that, currently we don't have support of lowpower node in mesh. Meaning all mesh node has to be main powered. This is one advantage of the BLE star network solution.
