RE: Interfacing nRF52810 (Connect SDK) with STM32

The serialization from the nRF5 SDK is not a good start, because the supporting libraries (e.g. bonding and flash storage) are not really portable to other MCU's.

So looking at what the Connectk SDK might have to offer instead seems like a better approach, I guess there are a few options (adding some links which might be for a different nRF device, but should be possible on the nRF52810 in principle, though I have not check flash and ram usage etc):

- Alternative 1: Use a peripheral example that resemble your application as a starting point, and add a serial interface with your own commands for the data transfer and link handling.

- Alternative 2: Run HCI on the nRF52810, and run the host on the STM32:

- Alternative 3: Use Remote procedure call:
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/nrf_rpc/README.html

- Alternative 4: Use BT shell:

Hello Markus,

Thanks for sharing the details. In our design, STM32 will be the host. It will need to send commands to start scanning, create a GAT service with a particular UUID, etc. Is there any document I can refer to for the same ? Thanks again for the quick revert.

Regards

Sachin

Hello Sachin,

referring to Zephyrs STM32 Temperature Sensor sample.
