Direction finding connectionless RX (locator)

[Sagar Bhosle]

I am currently working on a Direction Finding project, but I am facing an issue in prj.conf.

I use an nRF52811 custom board for Direction Finding. In the board selection under the build configuration, I created a custom board and built it, but the build fails due to RAM size overflow by 704 bytes.

How can I modify prj.conf to optimize the code? I tried selecting Optimize for Size in the build configuration, but it did not reduce the size."

Would you like help with optimizing prj.conf to fit within the RAM constraints

this is my prj.conf :-   

CONFIG_BT=y

CONFIG_BT_DEVICE_NAME="DF Connectionless Locator App"

CONFIG_BT_EXT_ADV=y

CONFIG_BT_PER_ADV_SYNC=y

CONFIG_BT_OBSERVER=y

# Enable Direction Finding Feature including AoA and AoD

CONFIG_BT_DF=y

CONFIG_BT_DF_CONNECTIONLESS_CTE_RX=y

Hello,

You can follow the Memory Optimization Guide for nRF Connect SDK. This guide explains how to reduce memory footprints by showcasing a basic sample and comparing it with the old nRF5 SDK. You could also find some information from our technical documentation on optimizing footprints. Make use of the Memory Report feature from VSCode to get an understanding of the memory usage.

Kind regards,
Abhijith

The smallest device suitable as a AoA receiver is the nRF52833, this due to the RAM requirements when you start receiving the CTE data.
