direct advertising while having established connection

[Matej]

Hi,

I'm wondering if I'am able to direct advertise when I have established connection (edit: according to this established connection nrf5x is master (central role))?

Of course with usage of S130 or S132.

Thank you for info.

BR, Matej

RK, thank you for your response and pointing me to specs (and yes thumbs up for nordic documentation –it's really great comparing with competition).

What I'm afraid of is inconsistent behavior of my system that direct advertiser, “advertise as much as possible/as soon as possible” – in case that I have no connection established, then I can direct advertise all the time and connection with smart device will be established very fast… In case that I have established connection with three devices (centrals) – there is less time to advertise and there is possibility that it takes longer that smart device receive advertise message in worst case can even happen that it won't receive advertise message in case that scan window and direct advertise message dismiss.

I think that's exactly what you're going to see. Direct advertising is going to get as much time as the softdevice can give it but you aren't going to get it running at the no-connection rate when you have other connections. There's only so much one radio can do and connections have timing requirements that just must be kept. I don't think there's anything much you can do about that.
