https://devzone.nordicsemi.com/f/nordic-q-a/21953/softdevice-s132-v4-flash-sizeHello, the specification states that SD132 v4 takes 120 KB flash and MBR 4 KB flash additionally. We only need the BLE protocol stack. Is there any way to reduce the SD132 flash size without compromising the BLE protocol stack functionality ?

The MBR is a part of the SoftDevice. Note that with an nRF52832 you still have 388 kB free space for you application after you have flashed the SoftDevice.</p><div style="clear:both;"></div>
