ERROR 4 [NRF_ERROR_NO_MEM] when connecting to nRF connect mobile application

[Msk]

I'm trying to merge the ble_Central example project with ble_app_template project. I've added 3 Custom services in the ble_app_template project by setting UUIDs and trying to send and receive data using nRF connect Mobile application. Everything works fine in with ble_app_template project alone.

When I merged it with ble central scanner project.it starts advertising and I am able to see the nRF device advertising in the nRF Connect app , however, whenever I try to establish connection with the device, it crashes and gives me ERROR 4 [NRF_ERROR_NO_MEM]. I'm using nRF52480 with SDK17.0.0. Can any one help me what causes this error.

Thanks in advance.

Increasing the memory retained for the SoftDevice is done by increasing the START address, as this address tells the application where to begin, which means that from 0x0000 to the START address can be used by the SoftDevice. I agree that it's strange you don't get a suggestion, but it might be because the application is already running when this occurs.

Best regards,

Hi,

by START address means, which address I should change here? there are like FLASH_PH_START, RAM_PH_START,  FLASH_START & RAM_START.

I tried increasing the RAM_START from 0x20002b28 to 0x2000CBF0, didn't make any difference though.

FLASH_START and RAM_START should be increased in order to give the SoftDevice more room.

Best regards,
