thank you very much, since we do need the attr table size increment feature, I think we could settle with S110 v8 for now. And use S120 for other product. Since S120 release not does not tell much about its S110 capacity, maybe you guys should include an line to let us know which S110 it is based on in the future release. That would be very helful. Thanks again.

The SDK will most likely be updated to support concurrent roles when the S130 is out, and there are indeed some challenges going from what we have now, but I am confident it will be better by then.

I am not sure about the bootloader, as the internal MBR might be different. I would test this thoroughly, or contact support for help backporting the changes if you have trouble.

As for release plans, I will have to refer you to contact our Sales department. They have the most up-to-date schedules, and they could also help us prioritize based on interest.

Thank you very much for the insightful details. S130 is relatively new, its peripheral throughput is not as good as S110/S120, we also plan to use it in another product in the future that feature dual role at the same time but not now. Also we realize you guys use the same name for device_manger peripheral & central ---> making it difficult to run dual mode simultaneously with device manager layer.

That is great to know S120's peripheral is an inter-version between S110 7.1.0 and S110 8.0.0. This makes me wonder whether the new bootloader (revision 0.6 released with sdk 8.0.0) with the new key-sharing works well with S120's ??

If possible could you please give a hint on when the S120 is released with S110 8.0.0 equivalent ?

Hi,

The answer to this question really depends on what you want from the peripheral.

"Bluetooth feature"-wise, the peripheral in S120 is equal to 7.1.0, and references the same qualification.
API-wise, it is closer to 8.0.0, and contains the newer encryption key format seen in the 8.0.0 and both include the API calls for all roles.
For proprietary features and bug-fixes, the S110 8.0.0 is indeed newer and contains fixes that are not available in the S120.

The intention of including a peripheral inside the S120 was to increase performance and compatibility when doing DFU. The throughput of the peripheral is greater, and some peer devices are still limited to central mode only (notably mobile phones). This makes it possible to boot into DFU mode as a peripheral and still retain the performance you are used to.

So if you want to be on the bleeding edge of S110 fixes and features, you want the S110 8.0.0. I would consider the S120 for its central capability over its peripheral ability, and rather look towards S130 if you need all roles simultaneously.

@RK We use the dual bank ble bootloader for user to upgrade product's firmware. During development our team did brick (bootloader couldn't start) several device occasionally when upgrade bootloader. In reality user can make lots of mistake such as selecting incorrect files (for firmware, it can still be recovered by re-upgrade). However if user make an mistake with SD, bootloader won't start --> device is bricked since SD is required for bootloader to work. And that will lead to lots of refund and return and frustration.

To sum up, we haven't developed any central features yet, but we like to have it with only a firmware upgrade rather than the dangerous SD upgrade. Hopefully that makes sense.

Thanks for the update. I didn't realize that S120 now offered a boot-time choice.

Not quite - not with v2.0.0 of S120 at least, that softdevice can be a peripheral or a central, although only one of them at a time, selectable at boot.

I don't understand the OP's contention that upgrading the softdevice may (sic)"bricked the device" and anyway as new versions are released in the future which may fix bugs then it's something you have to be prepared to do. I'd put on the softdevice which has the capabilities I needed and deal with upgrading that as and when I need to.

Hi hathach,

S110 and S120 do different things. S110 is for implementing peripherals and S120 is for implementing central apps that connect to peripherals. If you need to do both in one device, S130 is what you are looking for.
