RE: SDK 14 - adding concurrent connections to HRS peripheral example

I had a typo when putting in the numbers for ble_app_hrs example the default settings in SDK 14. Mine were the same as yours (it was 0x20002a58 NOT 0x20002558).

I still could not get NRF_LOG to show the numbers you did after changing the link counts, so I decided to re-install the SDK again and now it is working properly. Thank you for your help!

Hi,

The working example with nothing changed has linker file as: MEMORY { FLASH (rx) : ORIGIN = 0x1f000, LENGTH = 0x61000 RAM (rwx) : ORIGIN = 0x20002558, LENGTH = 0xdaa8 }

I'm not seeing these numbers. For ble_app_hrs example the default settings in SDK 14 are

MEMORY
{
  FLASH (rx) : ORIGIN = 0x23000, LENGTH = 0x5d000
  RAM (rwx) :  ORIGIN = 0x20002a58, LENGTH = 0xd5a8
}

When I change the NRF_SDH_BLE_PERIPHERAL_LINK_COUNT and NRF_SDH_BLE_TOTAL_LINK_COUNT to 3, i got this output from the logger :

<warning> nrf_sdh_ble: RAM start should be adjusted to 0x20004C18.
<warning> nrf_sdh_ble: RAM size should be adjusted to 0xB3E8.

After applying these changes, i.e. RAM (rwx) : ORIGIN = 0x20004C18, LENGTH = 0xB3E8, everything worked fine here.
