Windows Swift pairing

[CY]

Hi,

Recently, I was trying to pair the nRF51822 development board by windows swift pairing.

While I turn on the swift pairing function, I still cannot use this feature to connect with the device.

Besides, I just get some information from microsoft's website:

Could you explain for me about what exactly the temrs mean and the relationship with the sample code?

What should I modified in hids_keyboard to get the function?

Thanks.

Hi,

 

Swift pair was added to the ble_app_hids_mouse example in SDK v15.1.

This implementation is shown in the main.c file for this example. Search for the define "SWIFT_PAIR_SUPPORTED" to see how it is handled in the application itself.

 

Kind regards,

Håkon

Hi Hakon, 

Thank you for your kindly reply.

I was trying to use the SDK but I just found that only support the nRF52832 (up to S132).

If I am using the nRF51822 PCA10028 (S130) is it possible to do the application by using SDKv11?

Actually, I have changed the main in my project by adding below item, but it could not work. It seems it need to do lots of change in advata,advertising, ble_gap.

BTW, I just found the information below that I could realize the reason for adding Microsoft information.

But why it need to add below functions?

#if SWIFT_PAIR_SUPPORTED == 1
init.advdata.p_manuf_specific_data = &m_sp_manuf_advdata;
sp_advdata_prepare(&init.advdata, &m_sp_advdata_buf);
#endif

ble_advertising_advdata_update(&m_advertising, &m_sp_advdata_buf, false)

Yes, some backporting is required in order to implement this on an older SDK, for instance the ble_advertising_advdata_update function.

This is to add the manufacturer specific data to the advertising payload per Microsoft's specification, so that you can later update the payload to enable swift pair (in BLE_ADV_EVT_FAST).
