About memory error of multiple communication in BLE

[Kova]

Hello
I am developing based on "multirole lesc" of BLE sample project.
In that project, the value of “NRF_SDH_BLE_CENTRAL_LINK_COUNT” in sdk_config.h was changed from 1 to 2 and the value of “NRF_SDH_BLE_TOTAL_LINK_COUNT” was changed from 2 to 3 in order to communicate with multiple peripheral devices.
The build was successful, but the following error occurred in the device output.

ERROR 4 [NRF_ERROR_NO_MEM]

The environment is as follows.
SoftDevice: S132
IDE: SES
BLE Device: NRF52832
SDK version: 15.30
peripheral project: ble_peripheral⇒ble_app_hrs
multirole project: experimental⇒ble_app_multirole_lesc
central project: ble_central⇒ble_app_hrs_c

Excuse me, but please tell me what to do. Thank you.

Hi.

If you read the warning it says:
"Insufficient RAM allocated for the SoftDevice. Change the RAM start location from 0x20002880 to 0x20002D50"

You can take a look at this tutorial which demonstrates how change the RAM start location, look at section 4 for Segger Embedded Studio :-)

Best regards,

Andreas

Hello AndreasF.
Sorry for my late reply.
I changed the RAM address according to what you told me.
Thank you!
