How to set receiver blocking for EN300328 certification in radio test example?

[Vishnu Pradeep]

We made two set of firmwares, one with radio test controllable through CLI  RTT and other with DTM. 
Problem with DTM firmware is our end product don't have UART or extra GPIOs available. So for the test purpose we are planning to remove one IC and connect the UART TX and RX for DTM.

Our doubts are

1. Can we set the receiver blocking with radio test example? If yes, how?

2. How to set receiver blocking with DTM command? 

3. For Japan market , can we set the transmitting carrier frequency (2402,2440,2480)with/without modulation signal(without modulation is applied for JPN market only) (requirement from the test lab)? How to do this in both radio test example and DTM example?

4.  If there is one firmware we can use for FCC/ETSI/EN300328 certification, which one is that? DTM or radio test?

For Japan market the below requirement is also given from the lab.

FOR JPN market, other product operated at FHSS mode:

For example if the product is using below technology:

1 FHSS with 4 operating frequency.

2 Channel spacing around 1MHz.

3 Operating frequency is 2402‐2480MHz

Will this be applicable for BLE?

Hi

The easiest in my opinion would be to do all this with DTM. RX blocking is not as straight-forward with the radio test example.

1. It should be possible to set up two radios with the radio test example, where one sends I.E. 1500 packets and the receiving end counts the received number of packets.

2. RX blocking with DTM can be done with a BLE tester. Multiple choices on Google here.

3. Yes, you can for example use the nRF Connect for Desktop DTM application to do just this. Doing this in the radio test example is described in the radio test sample documentation.

4. You can use both DTM and radio test for this, just test one channel at a time.

Best regards,

Thanks for the clarification.

The problem is we don't have free GPIOs to use UART for DTM. So we are planning to go ahead with radio test example in which commands are send from CLI RTT. So would like to know,

1. can we add CLI RTT to DTM example and do receiver blocking test?

2. So you mean we can do receive blocking with radio test example? What modifications to do in the example to achieve that?
