no timer interrupt after softdevice off

[air]

 Hello,
I am using nrf51822 / SDK 12.3 / SD 130-2.0.1.

When a normal timer is set and softdevice off, the timer interrupt does not occur.

In SDK 10 / SD 110-8.0.0, timer interrupt occurred.

The purpose of the timer interrupt is to reenable the softdevice again after a certain period of time.

Only SDK/SD is updated with the same code.

I'll try several things, but first I ask why.

Thank you.

Hi,

It's been a while since sdk 12, and even longer since sdk 10. But could you check if the timer you use for app_timer is still running after the SD is disabled?

RTC1 is still enabled and the counter doesn't increase after SD disable

Simultaneously with BLE operation, it communicates with external devices using GPIO.

At this time, I turn OFF SD when communication starts due to communication error due to BLE event.

During communication, if there is an error in receiving data, SD is reenabled again after a certain time.

By replacing it with Timer 2, the whole operation was solved without additional change.

I think the SD should only use timer0, but it might be that timer1 is used somewhere in the application /sdk. But as long as timer2 is available that should be ok to use as well.
