关于堆栈通过自己的数据和数据重置

嗨对话框，

我现在使用堆栈来做广告,the period of time I have set is 2.5s by using the timer . I am using the "current_role" in my program for controlling the role switching in the program"app_task.c" and "app.c". However when it is running for 25 times for the role switching, it will reset the whole program, and lost all the things put into the ram before, could you please help with this issue?

以下是app_task.c：的某些部分：
extern volatile uint8_t current_role;

int app_switch_role（ke_msg_id_t msgid，void * param，ke_task_id_t dest_id，ke_task_id_t src_id）
{
app_gapm_reset_op（）;

return（ke_msg_consumed）;
}

static const struct ke_msg_handler app_gap_process_handlers [] =
{
{gapm_device_ready_ind，（ke_msg_func_t）gapm_device_ready_ind_handler}，
{gapm_cmp_evt，（ke_msg_func_t）gapm_cmp_evt_handler}，
{gapc_cmp_evt，（ke_msg_func_t）gapc_cmp_evt_handler}，
{gapc_connection_req_ind，（ke_msg_func_t）gapc_connection_req_ind_handler}，
{gapc_disconnect_ind，（ke_msg_func_t）gapc_disconnect_ind_handler}，

};
