Diferance between v9.0.0 & V12.2

[Kiran]

Dear all

Currently we are using version 9.0.0 (nrf51422 family---> using for 51822 chip) & now we are trying to use 12.2 ("nRF5_SDK_12.2.0_f012efa.zip").

1. Is there any difference? in both the versions (9.0.0 & 12.2)

2. Can I use the same i.e. for V12.2 (nrf51422 family selection ---> for 51822 chip)

Best Regards Kiran Padol

No, Nordic guys just change numbers and release the same version periodically. There is a big display in their office, saying something like: "Nobody noticed no SDK changes for 490 days" (it increments every day).

Of course there are changes, managing drivers changed dramatically since version 9.0.0, there are plenty of workarounds implemented, new bootloader, new flash libraries etc, lots of it. Also, S110 is not supported anymore, S130 Is to be used for bluetooth on nRF51. Detailed description of every release is available on infocenter, just read it.

You can use nRF51822 the same as nRF51422, unless you are not trying to do something with ant+.
