central to multiple peripherals

[ps_anu]

Hi..

 I want to implement a application ,i want to make a connection one central to multiple peripherals and  to transfer the data from the one  central to particular  peripheral with the time period without disconnecting other peripherals .

Is it possible ?

if so which one is better  to differentiate the peripherals  using connection handle or uuid. how to do that ?

please suggest me

Hi. 

Yes, this is possible. 

I suggest that you take a look at the BLE Multi-link Example. 
The BLE Multi-link Central example application shows how one central can be connected to several peripherals simultaneously. We have use two or more BLE Blinky Application as peripherals.

BLE Multi-link Central:
You can find the source code and the project file of the example in the following folder: <InstallFolder>\examples\ble_central\ble_app_multilink_central

BLE Multi-link Peripheral:
You can find the source code and the project file of the example in the following folder: <InstallFolder>\examples\ble_peripheral\ble_app_blinky

Best regards,

Hi ...

joakim .... i know we can  connect   central to multiple peripherals ... I want  to clarify that can we connect able to the different uuid by naming it .. because i want to send the data to particular peripheral device from client .... not all peripheral at the same time . 

Example .  A is central.   B,C,D,E are peripherals . I want to connect all the peripherals by naming it different uuid .  Now , I want to pass the data only to A by using uuid of the B . it is possible ? Like wise I want to send the data to only C by using uuid of the C peripheral device  ... Is it possible ???  .. I want to send the data individually 

Thanks

Hi. 

Sorry about the delay, I've been out of office.

 Yes, that is possible.

yes.. thankyou for your response , how to send the message using device mac address or uuid of device . where to declare and specify 

Thanks&Regards

I would say that this is easier to do simply using the conn_handle.

You can take a look at the relay example to see how this is done.
