https://devzone.nordicsemi.com/f/nordic-q-a/116050/convinient-way-to-integrate-nrf-module-to-a-systemGood Evening! We are designing a project using BLE; however, it requires quite heavy processing. We are still at a low level with pure C to save power, but the MCUs offered by nRF are too weak for us, and we don&#39;t want to change everything.

Is it the STM module you mention? If so, what kind of application is running on this device? What are you planning on using the nRF52811 for here exactly. It is one of the smaller devices we have in terms of RAM and flash memory and number of peripherals, etc. So if you&#39;re doing a lot of heavy processing that might not be the way to go. Can you share some more details on what your use case is exactly so I understand what it is you want to do, and what application you&#39;re after. You say you&#39;re working on bare metal C programming for saving power, but I&#39;d strongly suggest using the <a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/index.html">nRF Connect SDK</a> based on the Zephyr RTOS, that has power management APIs to keep the device power lower. If not, you can use the <a href="https://docs.nordicsemi.com/bundle/sdk_nrf5_v17.1.0/page/index.html">nRF5 SDK</a>, which is older, but apart from the SoftDevice link layer it is lower level, check it out here. Note that new features are not coming to this SDK as it is in maintenance mode.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
