Upgrading softdevice through OTA causes application can't work.

[zqclzz]

Upgrade softdevice through OTA (old softdevice version is s110_7.0.0, new softdevice version is s110_7.3.0), when complete upgrading, the application can't work but only the DFU works. Why? Does the softdevice ugrading delet delete the application firmware? How to upgrade softdevice through OTA without effecting application?

Hi Zqclzz,

When you do softdevice update, the bootloader need to erase the application to have enough space for receiving the new image. So you need to update the application after you have finished update the new softdevice.
