What about eclipse ?

I applied the value:

RAM_START=0x20002C60

RAM_SIZE=0xD3A0

Inside the linker option macros (can view guide from here: https://devzone.nordicsemi.com/f/nordic-q-a/34853/nrf_shd_ble_enable-function-error-code-4-no-memeory-for-operation) and it worked 🙂.

Thank you!

I am using nRF52832, can you suggest how much should I put its values too?

Hi,

That error means NRF_ERROR_NO_MEM, which means you have to allocate more memory. You have to change your RAM_START and RAM_SIZE.

I am using nRF52832 with SDK 15.3.0 but I am getting this error:

Any leads would be greatly appreciated.

I am looking for a similar application and I followed your solution but it is not working, can you please provide further insight into it. I want to modify the ble_app_beacon example.

You can find RAM_size by:

Right click on your project -> "Edit Options" -> At top left change your configurations to common -> Linker -> "Section Placement Macros"

Which IDE are you using?

I changed:

In sdk_config.h

#define NRF_SDH_BLE_PERIPHERAL_LINK_COUNT 1 //was 0

In nrf_sdh_ble.c:

#define RAM_START 0x20001D88 //was 0x20000000

However I could not find RAM_SIZE

And I get the error messages:

<warning> nrf_sdh_ble: Insufficient RAM allocated for the SoftDevice.
<warning> nrf_sdh_ble: Change the RAM start location from 0x200018A8 to 0x20001D88.
<warning> nrf_sdh_ble: Maximum RAM size for application is 0x10000.
<error> nrf_sdh_ble: sd_ble_enable() returned NRF_ERROR_NO_MEM.
<error> app: Fatal error
<warning> app: System reset

How can I solve thie?

You also have to change your NRF_SDH_BLE_PERIPHERAL_LINK_COUNT to 1 and your RAM accordingly. Change your RAM_START to 0x20001D88 and RAM_SIZE to 0xE278.

Hi Mttrinh,

I changed the line

m_adv_params.properties.type = BLE_GAP_ADV_TYPE_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED;

to:

m_adv_params.properties.type = BLE_GAP_ADV_TYPE_CONNECTABLE_SCANNABLE_UNDIRECTED;

But that is not sufficient, because it gives the error (through the USB-commport):

<info> app: Beacon example started.

<error> app: Fatal error

<warning> app: System reset

And it does not send any BLE message.

To my impression, there is a lot more to change. But I hope somebody else already invented this wheel.

Hi,

We don't have any examples that does exactly this. You can change the advertising type to connectable in advertising init if you want to allow connections.
