Hi Andreas,

You have to check that your chip revison is compatible with our newer SDKs and SoftDevices, see this page on our Infocenter.

You can identity which chip revision your device uses by looking at the chip markings and comparing them to the this overview.

If your device uses a revision 2 chip, then it will not be able to use our newest SDKs and SoftDevices.

Update:

The s110 v.6.x.x does not have a Master Boot Record (MBR)(introduced in s110 v.7.x.x) which is required to perform updates of SoftDevice and Bootloader.

Yes, as my colleauge stated in the Mypage ticket, the s110 v.6.x.x does not have a Master Boot Record (MBR)(introduced in s110 v.7.x.x) which is required to perform updates of softdevice and bootloader. I suggest that you direct further questions regarding the custom firmware in Mypage as we will be able to give you better and more dedicated support there.
