20 connections simultaneously

[Corentin]

Hello,

The softdevice S132_SDS_v4.1 spécification write that supports 20 connections at the same time. I would like to know if it's possible to have 1 central and 20 peripherals that send information each 30ms at the same time ?

No. 20 means 20, not 20 + 1;) According to the specification S132 V4 cannot handle 30ms interval with all 20 links active, see Suggested intervals section. If you need more than 20 concurrent links you can try to use some open source stacks which support nRF52 and claim 32 (or maybe even more) concurrent links (but that means to change the application architecture indeed, they typically use completely different GAP/GATT/LL APIs as well as other things such as restricted flash erase access etc.)

Hi endnode,

Which document specifies '32 concurrent links'?
