Hi,

This looks like a bug, the S130 SoftDevice for nRF51-series uses PPI groups 2 - 3, but the S132 uses PPI groups 4 - 5

SD_PPI_GROUPS_USED is used by SDK to know which PPI groups are reserved by SoftDevice. In S132 v4.0.2 this macros is equal to 0xC. This means that groups #2 and #3 are used by SoftDevice and is not available to user. But according to infocenter this groups is available for user application.

There is no error when I allocate group #0. Application use group to drive pin (similar to PWM). And there is no activity on pin when I use group #0. But everthing is ok with group #1 (app allocates two groups, and use only one).

Hi,

What do you mean by "SDK allow to use 0,1,4,5" ?

Are you getting any erros when you try to use group 0?
