Changing software of a certified module

Thank you for quick and good answers. We do not intend to change the HW on the module. However, if the certificate is done on the SoftDevice we need for the intended application I do not know. I have to ask the module manufacturer since the QDID from their certificate is not in the list of nordic QDIDs infocenter.nordicsemi.com/.../nRF51_Series_Compatibility_Matrix_v2.5.pdf

Hi,

We have designed and certified nRF51 modules for customers and have preliminary nRF52 modules. We can provide full certification, testing, etc. Feel free to contact us at info@argenox.com.

To Expand on Einar's response, the Bluetooth Certification of a module depends on the components used. The firmware of the system (application) can readily change as it is not a component per se. However the BLE stack softdevice must remain exactly the same because it has a QDID and is referenced by the Bluetooth certification of the final module. Using a different version of the SoftDevice implies a different QDID and therefore the certification would not be valid.

You can see the various QDIDs used in nRF51 SoftDevices in the Compatibility Matrix: infocenter.nordicsemi.com/.../nRF51_Series_Compatibility_Matrix_v2.5.pdf

Using a certified 3rd Party Bluetooth Smart Module, you are allowed to change the application software, and the BLE certification will still be valid. However you have to use it with the certified BLE stack (SoftDevice), and you are cannot make any hardware changes on the module it self.
