about timeslot

[Liny]

Hi, I'm currently trying to use the Timeslot feature in the nRF SDK 5 and have a few questions:

1. Can Timeslot be used during the advertising phase? Specifically, during the BLE advertising phase, can I use the radio for some private tasks?

2. Suppose I'm a standard BLE keyboard with a connection interval of 7.5ms. Within one connection interval, approximately how much idle time (Timeslot) can I request to perform private tasks? Is this duration stable? Is the length of granted time consistent each time a request is made?

3. Do the nRF54 series and nRF Connect SDK support the Timeslot functionality and its related APIs?

Hi!

Yes, that is possible.

Suppose I'm a standard BLE keyboard with a connection interval of 7.5ms. Within one connection interval, approximately how much idle time (Timeslot) can I request to perform private tasks? Is this duration stable? Is the length of granted time consistent each time a request is made?

There should be a few ms left for the timeslot. But it's variable and not guaranteed to be consistent, as Radio Timeslot API timing-activity is scheduled independently of any other timing activity, hence it can collide with any other timing-activity in the SoftDevice.

Do the nRF54 series and nRF Connect SDK support the Timeslot functionality and its related APIs?

Yes. A timeslot sample can be found here:
