Minimal latency (gazell) link

[wizath]

Hi,

I'm trying to set up a link between one master and 10~ slave devices. All I need is a lowest latency and little data rate for short time.

And there is my question :

1. What are the minimal connection intervals in gazell library ?
2. And is there any example like ble_app_uart to set up simple communication between two (or more) devices?

Thanks for help

Hi,

1. For minimum connection intervals look at this answer.

2. If you are referring to Gazell, then no. But you can setup several devices to send to one host, and differentiate them for instance by having a header in the beginning of the payload to identify each device. If you require bi-directional data, then each device should use it's unique communication pipe, else the bidirectional data might be sent from the host to the wrong device. If you have more than 8 devices, then I assume it might be possible for the host to dynamically update the pipe addresses in intervals (e.g. every few ms), so it is appears as if it has more communication pipes than it really does.
