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.

we are using the module HRM1026. I have got the answer through Mypage. Yes it should be possible to flash new softdevice and bootloader with 7 and above but since we dont have that we have to somehow make a custom software that does that for us.

Ok, which specific module are you using? The module vendor should list which nrf51822 variant thats used in the specs. Have you go the answers here on DevZone or through Mypage? When you say that "Softdevices from 7 and above will work to update the softdevice and bootloader." do you mean that you're able to update the bootloader and softdevice if you flash the module with a v7 SoftDevice ?

Hi I use a module so it is hard to check for the marking on the chip. But I have used the latest sdk in another firmware and it seems to work alright so I guess there is no problem with that. I have got answers from Nordic Semiconductor that updating this wont be easy since we use an old softdevice. Softdevices from 7 and above will work to update the softdevice and bootloader.

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.
