SD 132 increasing RAM

[AB]

I have modified the experimental_ble_eddystone app to be a connectable beacon. To do this I need to increase the peripheral_link_count to 1 from 0. In others words I want to make it a connectable beacon.

I get err_code 12 when I enable the softdevice by err_code = softdevice_enable(&ble_enable_params).

I guess I need to increase the RAM size given the connection. How much do I increase the RAM and where. I am using Keal and SD132 2.0.0.2 alpha.

Thanks!

If you're using 2.0.0-2 alpha then NRF_ERROR_NO_MEM, as it tells you in the documentation, means you need to reduce the size of the attribute table.

If you move to a later release, I think anything after 2.0.0-7, that allows you to adjust the amount of memory used by the softdevice instead so the whole thing is completely tuneable. In that case the error code returned changes and the enable call changes to take a pointer to the start of user memory.

So either reduce your attribute table size if you want to continue on that version of the softdevice, or make the changes to move to the latest one and tune the attribute table size and the memory.

Thanks RK I have installed 2.0.0-7 and I have the following issue.

define PERIPHERAL_LINK_COUNT 1

err_code = softdevice_enable_get_default_config(CENTRAL_LINK_COUNT, PERIPHERAL_LINK_COUNT, &ble_enable_params);

err_code = softdevice_enable(&ble_enable_params);

results in err_code =12

It works fine (err_code = 0) when I have

define PERIPHERAL_LINK_COUNT 0 err_code = softdevice_enable_get_default_config(CENTRAL_LINK_COUNT, PERIPHERAL_LINK_COUNT, &ble_enable_params);

err_code = softdevice_enable(&ble_enable_params);
