NRF_ERROR_NO_MEM error in ble_app_uart example

[MJ23]

Hi!

I am using the following setup to run the "ble_app_uart" example:

• nRF5 SDK 17.1.0
• BMD 360 EVAL Board (nRF52811)
• SEGGER Embedded Studio V6.32a

I selected the pca10056e (s112) example project and modified the following things:

• I edited the project file with a text editor and replaced "112" with "113" because the preferred SoftDevice is S113.
• I changed the "Section Placement Macros" to the following values:

devzone.nordicsemi.com/.../adjustment-of-ram-and-flash-memory

FLASH_PH_START=0x0
FLASH_PH_SIZE=0x30000

RAM_PH_START=0x20000000

RAM_PH_SIZE=0x6000

FLASH_START=0x1C000

FLASH_SIZE=0x17000

RAM_START=0x20001198

RAM_SIZE=0x3d38

The project builds fine and I can debug the program.

Nevertheless, I receive the following error in "ble_stack_init":
nrf_sdh_ble: sd_ble_enable() returned NRF_ERROR_NO_MEM.

Any idea what I am missing?

Thank you!

Best, Michael

Hi,

I assume the S113 softdevice may require a bit more RAM than the S112 softdevice. The nrf_sdh_ble_enable() should output the recommended values for RAM START and RAM SIZE, similiar to this thread (f you build with debug and not release build):
sd_ble_enable() returned NRF_ERROR_NO_MEM on initalization nRF528232 

Best regards,
