Should I migrate to SDK5.0.0 for project based on SDK4.2.2 & Softdevice S310?

[Joseph]

Hello,

I am developing a project using nRF51922 and S310, and the project is built using SDK4.2.2 with the modifications mentioned in a document called "nRF51922 - ble application porting.pdf".

We know we have to switch to nRF51422 V2.0 when it is made available.

The question now I am facing is whether I should migrate to SDK5.0.0? SDK5.0.0 do not support S310 and some modifications are needed, right?

It seems that something have been changed in SDK5.0.0, namely, there is no ble_stack_handler.h, I find softdevice_handler.h instead, so part of the information mentioned in "nRF51922 - ble application porting.pdf" seems no longer apply, please advise.

Regards, Joseph

Hi Joseph

As you are probably aware of, the nRF51922 will not go into production. Instead, the S310 dual BLE/ANT stack will be provided for the new nRF51422 rev2 chip.

I am not sure if the hardware for nRF51422 is available yet. To get information about that I would suggest to contact your Nordic's sales representative. I think if it is not available now it should at least be available early january.

The nRF51922 with preprogrammed S310 softdevice is not compatible with the nRF51 SDK v5.0.0 or higher. Instead, SDK51 v5.1.0 is now available for the new nRF51422 rev2, which should support both S210 v3.0.0 beta and S310 v1.0.0 alpha softdevices. The next step for you would therefore be to port your application to the SDK51 v5.1.0 and S310 v1.0.0 alpha softdevice when you receive your nRF51422 rev2 kit.
