Hi, 
 If you stop the execution somewhere in the application code e.g. by using a breakpoint, you can step forward from there if you set the PRIMASK CPU system register to 1 after hitting the breakpoint. You can do this in the "Registers" window in Keil while in debugging mode. 
 There are a couple of limitations: You can only step until you hit an sd_* API call or return from an ISR, and you can not set PRIMASK back to 0 and resume execution as stopping the execution breaks the real time properties of the BLE stack. Also, no new interrupts will happen after PRIMASK is set to 1. 
 I hope this helps.
