nRF52805 BLE throughput sample

[Felipe1]

Hi Nordic Semiconductor Expert,

I would like to measure the BLE throughput over nRF52805.

Seeing BLE Throughput sample in nRF Connect SDK below, this SoC platform is not supported.

Bluetooth: Throughput — nRF Connect SDK 2.8.99 documentation

The build fails due to the Flash/RAM size overflow, and then I tried to built it on the nRF52832 build configuration.

Memory region Used Size Region Size %age Used
FLASH: 277020 B 512 KB 52.84%
RAM: 61692 B 64 KB 94.13%
IDT_LIST: 0 GB 32 KB 0.00%

Then I used nRFKconfig GUI and then tried to reduce the memory size.

Referrring to the following articles as well, I tried to reduce the memory but I could not reach the nRF52805 memory size.

Memory Optimization with the nRF Connect SDK - Software - nRF Connect SDK guides - Nordic DevZone

Memory footprint optimization

Are there any methods to fit in the memory size (e.g. recommended prj_minimal.conf) or any alternative measurement tools?

Thank you.

Hi, 

For reference, you can find minimal footprint configurations of the Bluetooth: Peripheral LBS sample in nrf/samples/bluetooth/peripheral_lbs/minimal.conf and the Bluetooth: Peripheral UART sample in nrf/samples/bluetooth/peripheral_uart/minimal.conf.

But it seems you already did what you can do. Since nRF52805 has limited flash/ram size, it cannot run complex samples.

Hi Amanda,

Thank you so much for your Info.  Yes, I referred to those minimal.conf files and tried to reduce the memory footprint, but I would not make it.  I would appreciate it if Nordic Semi would provide any alternative tools in the future.

Thank you again,

Toru
