Timeslot session does not close properly

[eyalasko]

Hi, 

Furhter to this post, I still getting unexplained behavior.

I use timeslot api to generate a burst of 10 hard-real time-pulses 29000us apart.

For the first 9 pulses, in the TIMER0 event callback I set the returned action to NRF_RADIO_SIGNAL_CALLBACK_ACTION_REQUEST_AND_END and the request.p_next member to the request structure.

On the 10th pulse, in the TIMER0 event callback, I set the return value to NRF_RADIO_SIGNAL_CALLBACK_ACTION_END (and the request.p_next to NULL).

I expect to get NRF_EVT_RADIO_SESSION_IDLE in the event signal handler but it does not show.

The above prevents (I assume) the session from being closed (does not get NRF_EVT_RADIO_SESSION_CLOSED event) and re-opened (I get NRF_ERROR_BUSY error)

What can be wrong? Why the session seem to remain busy and doesn't move to IDLE ?

Thanks

Hi eyalasko,

Thanks for giving the information in the previous thread. So this problem in this thread is not related to the previous one? 

 

I expect to get NRF_EVT_RADIO_SESSION_IDLE in the event signal handler but it does not show.

 You must get some EVT, if you did not get NRF_EVT_RADIO_SESSION_IDLE then there are only two possibilities, that there is some other context running at higher/equal priority to mask the timeslot events or

you may be getting some other event apart from IDLE. Even though that should not happen, it will be a matter to investigate if no events were received at all after NRF_RADIO_SIGNAL_CALLBACK_ACTION_END

Aren't timeslot events the highest priority (0)? How they can be masked?

And even if masked, won't they be triggered after the masking context terminates?

Yes, they should be highest priority. This behavior does not seem correct, can you please help me replicate the problem so that i can do some debugging on my side.
