Enter Tx CW mode firmware

[Tarik]

Hi,

1) I need to test the frequency accuracy as well as the spurious emissions. I have been trying with the Radio_test example but it needs some special UART configuration to receive the commands. And it will take a lot of time to setup the right UART connection and debug it. Is there an example or a short cut to put the firmware in CW mode directly at startup without the need for any serial connection nor commands.

2) Is there a way to use only the JLink SWD interface to control the direct test mode with a "rohde&schwarz bluetooth tester" or is it mandatory to have the TX and RX pins on the JLink connected to some NRF chip UART pins ?

Thanks for your help

Hi,

1. We do not have any ready made example for this. I think using uart is probably the easiest way to test this (it is possible to connect through a nordic DK to use the segger uart interface). Notice that the radio test example is written in such a way, that you can use the radio test module without cli, if case you want to write custom fw to set up a cw. But I think that might require a bit more work that CLI overt the uart interface.

2. Unfortunately we do not have a Rohde&schwartz bluetooth tester. But most likely it has a uart DTM interface that you can use togheter with the DTM example from our SDK. notice that we are testing using an Anritzu tester and have not validated against the R&S tester. If you want to control this using SWD, that is possible. But it requirese rewriting the DTM test module, which will require some sw work on your end (i..e not something we have support for). UART DTM seems to be the standard for the DTM testers.
