52811 central SDK

I want to use 52811 as central deice, which SDK  and  SoftDevice should I use? 

https://www.nordicsemi.com/Software-and-tools/Software/S140

It says: SoftDevice S140 is a feature-rich BluetoothRegistered Low Energy protocol stack for the nRF52811, nRF52820, nRF52833 and nRF52840 System-on-Chips (SoCs). 

But I use nRF5SDK160098a08e2\examples\ble_central\ble_app_hrs_c\pca10056\s140\arm5_no_packs, change the device to nRF52811_xxAA, build, then I get errors.

  • Hi,

    s140 is currently the only Softdevice with GAP Central role support that we have qualified for the 52811, so that is the one you need to use  (Combability matrix - SDKs and SoftDevices). However, this Softdfevice variant is significantly larger and leaves only 44KB of flash to the application. The ble_app_hrs_c example will not fit so I suggest you start with the less complex ble_blinky_c example instead (takes up less than 30K). 

    As you can see from the "Developing for nRF52811" guide, there are a few steps required to convert a 52840 example (pca10056 is the board name for nRF52840 DK) to run on a 52811 target. You may use project settings from another pca10056e project as a reference for this conversion.
