https://devzone.nordicsemi.com/f/nordic-q-a/41721/nrf51-ble-soft-deviceHi We are using a BLE soft device on our nRF51822 which is about 8kb big. Anyone have one that is smaller in size?en-USTelligent Community 13Thu, 03 Jan 2019 07:07:22 GMThttps://devzone.nordicsemi.com/thread/163644?ContentTypeID=1Thu, 03 Jan 2019 07:07:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fb7db685-482b-4f3d-9b94-30db15093e62AndreasF<p>Hi.</p> <p>Yes, if the SoftDevice is not enabled it uses 8 bytes, if its enabled it uses 0x1288 + Configurable resources, which is minimum 0x1230 for S130 2.0.0-7.alpha</p> <p>I do not know if there is any other SoftDevice that uses a lower amount of RAM.</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/163587?ContentTypeID=1Wed, 02 Jan 2019 22:19:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8f668ad3-d6a3-4b26-8c41-6c9a4032fe61WernerVorster<p>Does the 4.5kB include the sd_ble_enable?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/163520?ContentTypeID=1Wed, 02 Jan 2019 15:54:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:453537f7-ee74-4efb-9cea-9aaa26051a1dWernerVorster<p>Thanks Andreas and Ashish, we only use BLE in the SoftDevice and that requires 8kb. Does that sound correct? Do you know of another SD that requires less, like S332 for example?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/163474?ContentTypeID=1Wed, 02 Jan 2019 14:16:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1e21b593-8127-4652-946e-4543b327ccb3AndreasF<p>Hi again and happy new year.</p> <p>I think SoftDevice S130 2.0.0-7.alpha is the one which requires the least amount of memory, 4.5 kB (0x1230 bytes).</p> <p>But check out the tutorial posted by Ashish above, and read if the SoftDevice you choose support the required features in the release note.</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/163233?ContentTypeID=1Sat, 29 Dec 2018 08:08:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bc08945c-afee-495d-a0bf-2e5e37ccb021Ashish<p>Hey,</p> <p></p> <p>You can check the table available in this&nbsp;<a href="https://devzone.nordicsemi.com/tutorials/b/getting-started/posts/adjustment-of-ram-and-flash-memory" rel="noopener noreferrer" target="_blank">tutorial</a>&nbsp;for RAM and FLASH consumption of various softdevice versions.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/163222?ContentTypeID=1Fri, 28 Dec 2018 22:20:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a354c3d5-9312-467c-b382-8299d0caea8cWernerVorster<p>Hi Andreas</p> <p></p> <p>Apologies, it uses 8kb or RAM and we need to reduce that because we&#39;re using nRF51822 with 32kb RAM total and we don&#39;t have enough to run our algorithms so we&#39;re trying to reduce RAM where possible.
