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?

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.

I have seen some chips that can achieve less and that is why I was asking. Just please edit the answer to be page 2638, because there is where is the quote ;)
