https://devzone.nordicsemi.com/f/nordic-q-a/126261/question-about-pllHi all, I am trying to get going very simple connection between multiple devices - specifically the end product is first-responder walkie-talkies. Effectively all I need is simple wireless modems for which I will provide on-air protocol myself.

There is a small note about this in the datasheet of the nRF24L01+.</p> <p>Also, make sure that you have not by accident configured the SPI polarity/mode wrong, in which case it may look right on the transmitter.</p> <p>Kenneth</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/557584?ContentTypeID=1Tue, 23 Dec 2025 13:15:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b8d98c70-f2f8-4947-9bfc-f33b686d45b2VE3ID<p>Thank you vidar, one could not expect anything more!&nbsp;&nbsp;</p> <p>godjul!</p> <p>Nigel</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/557583?ContentTypeID=1Tue, 23 Dec 2025 12:57:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2cc84444-b257-44d6-90d4-f991b7b3e3efVidar Berg<p>Hello Nigel,</p> <p><span>Unfortunately, those who are familiar with this chip have already left for the holidays.
