52811 central SDK

Hi,

The loader does a pre-check to see if the FW image contains any data outside of the valid address range for the target chip. So maybe you have forgotten to update the memory layout for the 52811? In any case, I did the same and converted the "pca10056" configuration to run on a 52811 target, see attached below.

I want BLE scanner, ble_app_uart, example run on 52811. Tried to port the code from pca10056 to pca10056e, build looks fine but it fails to load the code. Can you share an example code built for 52811 using pca10056e for S140 softdevice.

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.
