Thank you! I don't use the nrf_log module so I disabled it in the sdk_config.h and the code start working.

Hi,

You can safely use PPI directly when the softdevice is enabled, but as a general rule; please check your err_code returns.

This is a function inside the nrf_log, and it looks like it is stuck for some reason. Hard to tell why without a call stack trace. Is your logging session open (either via RTT or UART) ? If you do not use the nrf_log module, I'd recommend that you disable it in your sdk_config.h

Best regards,

Håkon

I think you need to look into the softdevice api functions and use the sd_ppi_* functions rather than the standard ppi functions since you presumably have the softdevice enabled. The softdevice utilized some of the ppi channels that I *think* the standard functions do not account for.
