Does nRF52810 supports concurrent Central + Peripheral role?

Scenario-1)

The problem would be the limited amount of RAM on the nRF52810. With more connections, the SoftDevice will require more RAM. With 8-10 connections, I estimate around 16-18 kB RAM usage for the SoftDevice. You then have 6 kB RAM left for the application. The increased number of connections will also increase the RAM usage of the application. The ble_app_multilink_central example application in SDK 14.2 with 8 connections uses around 17 kB RAM. That is 33 KB RAM usage in total for application + SoftDevice. I recommend to use the nRF52832 if you need this scenario/configuration.

Scenario-2)

I see no problem with this scenario. You will need to use S132 v5.1.0

Yup. But as per the latest post both the scenarios seems achievable with some limitations in a number of connections may be.

That's a very recent post (under 2 weeks ago) - so looks like they have only just got it working.

Good to know - hopefully they will update those earlier posts ...

Thanks, Awneil.

The answer covers both scenarios.

Hi Awneil,

Thanks for the quick response.

Please share your views on scenario-2.

nRF52810 does not support Central at all !

nRF52810 does not support S132.

(or is it the S132 does not support nRF52810?)
