Nrf8002 : Testing General Reflexions

Yes, you would have to program the nrf51822 DK with the DTM example in the SDK. This should set it up as a DTM device so the Python script can control it. The Python script manages the test and calculates the PER.

Just to be more precise, i'd like to do as stated in nAN34 on page 6 : use the nRF51822-DK as a lower tester. If i understood well, it would be used as a emitter while testing RX of 8002 (which would be controlled through the UART line, as in the Python script attached) and as a receiver while testing TX of 8002....

I'm not sure, but in that case, the nRF51822-DK would be the Golden Sample from the python script ? Itselfs controlled in DTM through UART interface... ? that would mean the nRF51822 is working also in DTM and that the python script already manages the whole test.... ?

Yes exactly, i'd like to use the nRF51822 to get and send packets to the 8002 in DTM. I didn't look exactly the python script but i know its existence.

What do you want to do? Do you want to use the nRF51822 to control the nRF8002? Did you look at the python scripts in the application note?

Hi Runar,

thanks for the feed back. Another point : is the nRF51822-DK enough to test the 8002 in DTM ?

Hi,

Yes. DTM is there to do RF tests only. You could get more information over Bluetooth, such as the device address and Device information (See the nRFgo studio for configuration). The Device would have to be configured for this to work. Note that DTM is not available after the configuration is written to OTP. DTM test can be done as described in nAN-34.
You can create multiple configurations and load these into ram using the production tool. As long as you have chosen “upload to RAM” when you click the “Store configuration to file” button you will be fine.
You could use on of the Device Identification fields for this, or you could use the device address for identification as this is a 48bit randomly generated address, but you should be aware that the device address is not available in iOS applications.

Best regards,
