That makes sense. The Softdevice does not permit the application direct access to the NVMC peripheral when it's active. Instead you have you use the sd_ API's as you did now (Flash memory API). Thanks for updating the thread.

For erase Operation we are used this function nrf_nvmc_page_erase();

Now we change to sd_flash_page_erase();

So now we can connect and disconnect using android Mobile is OK.

Thanks

Hello,

Can you show with a code snippet how you are storing the data to flash? The error indicates that the peripheral stopped responding to the phone.
