https://devzone.nordicsemi.com/f/nordic-q-a/47069/s132-v2-0-0-softdevice-assert-at-pc-0x1a986We are using s132_nrf52_2.0.0_softdevice.hex with the nrf52832 . We have been having problems with our devices asserting when in the field. Unfortunately we have not been able to reproduce this issue in-house, so I can&#39;t say under what circumstancesen-USTelligent Community 13Thu, 09 May 2019 12:25:00 GMThttps://devzone.nordicsemi.com/thread/186179?ContentTypeID=1Thu, 09 May 2019 12:25:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c170829e-1ab5-402e-a825-ab0ea88992aeSigurd<p>Hi,</p> [quote userid="79565" url="~/f/nordic-q-a/47069/s132-v2-0-0-softdevice-assert-at-pc-0x1a986"]We are using the Timeslot API, so I suspect that this may well be due to a timing violation.[/quote] <p>Your suspicion is correct</p> <p>The assert pc value indicates that you have spent too much time in the timeslot. From the SDS, see <a href="https://infocenter.nordicsemi.com/topic/sds_s132/SDS/s1xx/concurrent_multiprotocol_tsl_api/ending_tsl_in_time.html?cp=3_4_1_0_8_1_6_4">this link</a>, &quot;<span>The application is responsible for keeping track </span>of timing within the Radio Timeslot and for ensuring that the application&rsquo;s use of the peripherals does not last for longer than the granted timeslot length.&quot;</p><div style="clear:both;"></div>
