always extend timeslot after another?(consecutive extension)

[summer]

According to S130_SDS_v2.0, I can choose to return NRF_RADIO_SIGNAL_CALLBACK_ACTION_NONE after NRF_RADIO_CALLBACK_SIGNAL_TYPE_EXTEND_SUCCEEDED to stop extend more timeslots. But all examples I can see always extend another timeslot after a success one. And what's worse, if I return NRF_RADIO_SIGNAL_CALLBACK_ACTION_NONE after NRF_RADIO_CALLBACK_SIGNAL_TYPE_EXTEND_SUCCEEDED, the program crashes. Could you please give me some explanations?

maybe I know the reason now. After return NRF_RADIO_SIGNAL_CALLBACK_ACTION_NONE and out of the timeslot, I still use TIMER0 which caused crash.

That is probably the reason yes.
