Hi 
 Dantes.gan said: 6.Only disable global interrupt when scheduling by RTOS kernel. 
 Most likely this is the issue. The SoftDevice is not designed to allow you to disable or delay its interrupts. 
 The SoftDevice comes with its own functions for disabling all non-SoftDevice interrupts which you should use instead, called sd_nvic_critical_region_enter() and sd_nvic_critical_region_exit() . 
 Could you try to use these functions instead in your RTOS kernel? 
 Best regards Torbjørn
