Can an application use more RAM if I make the attribute table size smaller?

[Kobayashi]

I'd like to optimize RAM usage due to lack of memory. According to the release note of S130, the size of the GATT server attribute table can be set. To get more RAM for an application, can I set smaller address to IRAM layout if I reduce attr_tab_size of sd_ble_enable?

I guess you are talking about S130 softdevice. I am not sure that this feature is available in other softdevices.

And Yes, you can reduce the the attribute size to as much as minumum (BLE_GATTS_ATTR_TAB_SIZE_MIN) and use the RAM available at the end of softdevice RAM area for user.

Thank you for the answer! I will try to use the RAM at the end of softdevice for my application.
