Is it possible to make the nRF52832 IC transmit a CW ?

And if yes, how do we make it doing so ?

Hello,

 

Is it possible to make the nRF52832 IC transmit a CW ?

Yes, the nRF5-series radios can output a unmodulated carrier.

For nRF5 SDK example, please see the peripheral/radio_test example, with command "start_tx_carrier":

Kind regards,

Hello Håkon

Thanks a lot for your answer - I will try that.

One more question.

For the moment, we do not have access to the interface of our DUT.

Such, we can not set up a CW, using the command you suggest.

Is it possible to make a special FW (for the nRF52832), such that, it automatically transmit a CW (at a particular frequency), when the DUT is turned/powered on ?

Hi Per,

 

Yes, that is possible, but you will have to modify the example to do so.

If you look into radio_cmd.c::cmd_tx_carrier_start(), you can see an example on how to initialize the radio_test module directly:

m_test_config.type                          = UNMODULATED_TX;
m_test_config.mode                          = m_config.mode;
m_test_config.params.unmodulated_tx.txpower = m_config.txpower;
m_test_config.params.unmodulated_tx.channel = m_config.channel_start;

radio_test_start(&m_test_config);

 

Kind regards,

Håkon
