nRF52810 running BLE HCI over SPI

mojangeex

HI all

So currently we are researching the following configuration. We have a main MCU running Zephyr RTOS and its connected to nRF52810 over SPI. Ideally we would like to se option to use nordic as HCI. I found example for BLE HCI SPI in NRF Connect sdk, however after building it it doesnt have enough RAM to link it together. 

Are there maybe other options to use the desired configuration? Maybe switching to nrf5 SDK?

Best regards

    Hi,

    The sample is configured to support 16 concurrent connections by default which requires a significant amount of RAM. Try to reduce the CONFIG_BT_MAX_CONN setting in the project configuration file (prj.conf) and see if that helps. The project will include the Softdevice controller if you're using the nRF connect SDK (you can confirm it is selected from the .config output).

    Best regards,
