Minimum connection interval

[Jorge]

Hi all,

Does in any chip with some constellation (different SD) the device allows less than 7.5ms for the connection interval? Or is this value the absolute minimum?

[Sigurd]

Hi,

The 7.5ms limit is defined by the Bluetooth Specification. From the BLUETOOTH SPECIFICATION Version 5.0 | Vol 6, Part B (page 2683):

The connInterval shall be a multiple of 1.25 ms in the range of 7.5 ms to 4.0 s.

Thank you Sigurd, Can you give my information where I can find this information (page or file)? I want to check all the possibilities for my project.
