One HR peripheral can connect to two phone at same time

[JohnCC]

Hi,

       We are currently developing the heartbeat belt product. Almost finished

But now there is a new requirement. Our heartbeat belt need to connect two phone at same time.

As we know, when the heartbeat belt is connected with one phone, other phones cannot see it.

So how can it be done?

We use SDK14 and softdevice version is S332 5.0.0

Thank you.

John.

Hi John, 

You shouldn't have a problem supporting multiple central at the same time. The S332 can support up to 20 concurrent links with any roles. 
You can have a look at the \examples\ble_peripheral\experimental\ble_app_multiperipheral\  example 

What you need to do is to configure NRF_SDH_BLE_PERIPHERAL_LINK_COUNT in sdk_config.h. For example in the example you can find this: 

In addition, you would need to re-start the advertising after you get connected because advertising is stopped automatically when connected. Please take a look at the on_connected() function in the example. You may want to use conn_handle in the callbacks to identify the connections.

Hi Hung,

      So I also need to change "Link_count" number and move on_connected(&p_ble_evt->evt.gap_evt) and on_disconnected(&p_ble_evt->evt.gap_evt) to our project. This will make our new requirement. Is it right?

Thank you.

John.

Hi John, 
Yes correct. Please try. There could be some minor change maybe needed but it's basically it.
