Muti-link peripheral Fatal error

[Jax]

SDK:15.2
KeilC:525
SoftDevices:s140_nrf52_6.1.0_softdevice
Hardware revisions: PCA10056

I have try the multiperipheral in 4 smart phone connection in blinky App.
But I need more than 4 peripheral smart phone to connect the PCA10056.
Change NRF_SDH_BLE_PERIPHERAL_LINK_COUNT from 5 to 8
After I build the project and download to PCA10056
There are error message from RTT Viewer.
0> <warning> nrf_sdh_ble: Insufficient RAM allocated for the SoftDevice.
0> <warning> nrf_sdh_ble: Change the RAM start location from 0x200037F0 to 0x200053F8.
0> <warning> nrf_sdh_ble: Maximum RAM size for application is 0x3AC08.
0> <error> nrf_sdh_ble: sd_ble_enable() returned NRF_ERROR_NO_MEM.

so I change setting in Keil C IRAM1:0x200053F8 and Size: 0x3AC08

After change start address and size.
RTT viewer only show 0> <error> app: Fatal error
What's going wrong or how could I fix it.

Hi Murugan

I found not only update NRF_SDH_BLE_PERIPHERAL_LINK_COUNT from 5 to 8, but also need to update NRF_SDH_BLE_TOTAL_LINK_COUNT to 8.

You should manual calculate NRF_SDH_BLE_PERIPHERAL_LINK_COUNT +  NRF_SDH_BLE_CENTRAL_LINK_COUNT = NRF_SDH_BLE_TOTAL_LINK_COUNT.

Hope it will help you.
