Nordic SDK and serialization library porting

[jyang]

Hi,

We are planning to update our product with the a Nordic BLE module in a serialization connection over a UART. The current product has a MCU EFM32GG290F1024. Our product has a RTOS already, and we need to run the BLE application with current applications together.

When porting the Nordic SDK and serialization library, there are several error messages coming out from IAR compiler, suggesting the SDK does not support Cortex M3 core. I have looked at the source code and have seen the support for Cortex M4 and even M0. 

Could I get some support and help from here.

Many thanks

I think porting the entire application with for instance peer manager and app timers to a different MCU will be very challening. Have you instead considering for instance taking the ble app uart example, and based on that example create your own custom UART commands to control the BLE interface of the nRF52.

Does it mean that the Nordic serialization solution is only applicable to a different MCU with Cortex M4 core? When I post my first question on this forum earlier, I got a response saying it would work with any simple MCU  https://devzone.nordicsemi.com/f/nordic-q-a/72878/what-is-the-hardware-requirements-for-an-external-mcu-to-run-a-serialized-connection-with-nordic-ble-module. 

You suggest a custom UART commands interface to control the BLE module. Does the Nordic have a reference for it? In our application, we want the device play as a peripheral to a mobile phone and at same time, connect several sensors as a central.

Thank you for your help.

I am not aware of any specific requirements to which ARM cortex you are using, however the code is written is very specifically for the nRF architecture and compilers, so even if you are able to port the serialized library, I expect you will get problems with the peer manager and flash data storage module that are very Nordic centric I would say.

That is why I suggest look into implementing custom UART commands, unfortunately I don't have any reference for it, but I still think it is the quickest path.
