6 notifications in one connection interval related issue

[bihu]

I want send out 6 notification in one connection interval. But now I only see 3 packets in my sniffer. So I want to know how to achieve this goal?

This picture is captured from S130's spec.

I have test the connection interval with 7.5ms, 50ms and 100ms.

• 2 packets when set 7.5ms interval.
• 3 packets when set 50 and 100ms interval.

BTW, which API can configure the tndist?

Thanks!

You will only use more power if you send more packets. So if you send 3 packts per connection even on BW_MID, that will use less power than sending 6 packets per connetion event with BW_HIGH given you use the same connection interval, same packet length. But you are also sending twice as much data.

Assuming you have a given number of packets you need to send, You will be able to send them in fewer connection event using the HIGH setting. In that case there might be a penelty if you end up sending more empty packets with the High configuration compared to MID or LOW. so it depends on your application and what it does.

I would recommend looking at the online power calculater as that will tell you the carge you use in each event in µC. So you can apply that to your use case.
