flash write problem

[hjjeon]

Dear Nordic guy, I'm developing with nrf51822. I have one question regarding flash write. In ble connected state,I have some error to write some data to flash. I want to write some data to flash. I describe detail reproducing step 1)in ble state, write some data with page write function 2) at master control panel app with phone , no problem exits. but when my device communicate with master control panel pc window version with usb ble dongle, pc program take the hci link loss event and my device reset. 3) I guess that pc program is correct and phone app is incorrect. I guess that when page write in connected state(radio active?),ble stack maybe goes to watchdog state, and finally, device reset caused by time ,and pc program take hci link loss event caused by device reset. 4) If my guess is correct, do you have any idea? idea is that correctly flash write in connected state. If it's impossible,please inform me.

Hi Hijeon, Could you let me know exactly which Softdevice you are using and which SDK version you based on ?

The S110 softdevice and its header files can be downloaded from here : www.nordicsemi.com/.../nRF51822-Development-Kit

If you are using SDK v5.x you don't have to modify your code to use with softdevice v6.0.0

If you are using SDK v4.x you would need to update your header file and modify your code since there are some major change in the way we manage the flash. However, I would suggest you to take the template example in SDK v5.x and integrate your code into the template than to modify your project to match with the new Softdevice.
