AppCore (SDK 2.1.1) not compatible with NetCore(SDK 1.9.1)

[Riccardo Gaiati]

Hi,

i am working with nrf5340, SDK 2.1.1

Previously I was using SDK 1.9.1. 

I have upgrade the AppCore with the application firmware built with SDK 2.1.1 but not the Netcore is still running the (net) application built with SDK 1.9.1.

The function bt_enable returns the error code -11. I debugged further and i saw that it is the function static int bt_rpmsg_open(void) to return that error.

Just a confirmation: Is this an expected behavior ? app and core shall be compiled with the same sdk?

Thanks in advance !

Hello Riccardo,

Yes, the rpmsg version needs to be the same for both the netcore and the appcore, so now that you have updated the appcore to a later version you must also upgrade the netcore to enable them to communicate properly with eachother, this is as expected :)
