send notification via gpiote interrupte

[lvshuo]

Hi, I am using a gpiote interrupte handle function to send a notification to the master,but I find when the sd_ble_gatts_hvx() function is used,the interrupte handle function breaks down and the system has no reaction.Therefore there is no any error notification.The odd thing is that when I delete the sd_ble_gatts_hvx() function ,the interrupte handle function will be normal.I don't know why.I am looking forward for your answer. My code is here: code.txt

Hi

This is probably because of priority violation. You can not call a sd_* function from a context with higher ARM priority than 2. The app_gpiote has a default ARM priority 1. Explanation on how the priorities work is given in this thread. To avoid this problem, you should use the scheduler to call sd_* functions form the main context, see this thread.
