Hi,

What are the difference between the different SoftDevice versions available? We are developing with the nRF52833 DK.

Thanks

Hi,

I am not aware of any specific overview for comparison, we recommend to always use the latest, since that have the latest features, bug fixes and qualification.

If you need detailed information I recommend to first check with softdevice is supported by the chip in question, e.g. for the nRF52833:
https://infocenter.nordicsemi.com/topic/comp_matrix_nrf52833/COMP/nrf52833/nRF52833_ic_rev_sdk_sd_comp_matrix.html

Then click on the specification for the various supported softdevices for more information:
https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/nrf52_softdevices.html

For instance you can find in the overview for S113:
"It supports up to four peripheral connections with an additional broadcaster role running concurrently"
https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/s113.html

While for s140 is says:
"The S140 SoftDevice supports running up to twenty connections concurrently"
https://infocenter.nordicsemi.com/topic/struct_nrf52/struct/s140.html 

Best regards,
Kenneth
