Changing the bandwidth of the receiver and transmitter

[jefegrande]

I am trying to modify the receiver an transmitter examples to change the default bandwidth on both the receiver and transmitter.  I have looked through documentation without any luck.

I am using  an nrf52940 DK as a receiver and a nrf52940 dongle as a transmitter. 

I am beginner with this area so I hope the solution is not too obvious haha.

Thank you in advance

Hi,

By bandwidth, do you mean the datarate MODE, or something else?

Best regards,

Hi, 

Thanks for the reply, I am talking about channel width. I think the default is 1 MHz and I want to change it to 2 MHz

Thank you

It is not possible to change this independently from the mode config. You can set the mode to Nrf_2Mbit in radio_configure(), which I believe should do what you want:

NRF_RADIO->MODE      = (RADIO_MODE_MODE_Nrf_2Mbit << RADIO_MODE_MODE_Pos);
