multi link central uart with multiple peripheral

[ps_anu]

hi...

I have modified the multi link central to multi link central uart , i can able to connect with 8 peripherals . One central getting connected with multiple peripheral, data are getting transfer between them. Now i want to differentiate the multiple peripherals to central , by using different uuid or name , product address . so that i can able to send the data to particular peripheral device from central .

how can i input the different uuid or name for multiple peripheral ?  i need some sample 

for example i am having central1 , peripherals (A,B,C,D) suppose A want to send message to D how can it send ? is it possible to transfer the data between the peripheral

suggest me a good one 

Thanks in advance

Hi 

Every link on the central side will be identified by a unique connection handle, which is a 16-bit value that starts at 0 and is incremented for each additional link. 

If you want you can map the connection handle to something else, such as the BLE address or a device name, but whenever you want to send something to a specific device you need to use the connection handle of that device to address it. 

It is important to know that each device could get a different connection handle each time it connects to the central, so the central will have to update the connection handle/BLE address map continuously as devices are disconnected and connected. 

It is also important to know that the connection handle for a link is not necessarily the same on the peripheral and central side (a peripheral with only one link to a master will only use connection handle 0).

Thank your explanation , how to send the data via uart using connection handle of specific device 

Best regards ,

I can try to provide a sample showing how to send a message from one link to the other, but it will have to be a side project that I work on when I have some free time. 

It is hard to say when I will have time to provide it.

Hi 

I haven't had time to work on this example yet, no. Until August I have various business trips and vacation coming up, so it is hard to predict when I will be able to look at this unfortunately. 

I you check in again with me in a couple of weeks I will try to provide an updated schedule. 

Best  regards
