Where can I find the reference design for RF matching network and antenna?</P><P>2. Where can I find the IDE tool and SDK and related documents for BLE application development?</P><P>3. We need to use the SWD interface as well as the ADC interface (they share the same IO pins). Any reference design for this?</P><P>4. The VREF of ADC is programmable: how can we set this parameter?</P><P>5. 32k external crystal is optional. If we decide to use the internal oscillator, what kind settings do we need to change?</P></BODY></HTML> Thu, 10 Mar 2016 19:03:15 GMT https://community.nxp.com/t5/Wireless-MCU/Where-to-find-SDK-and-reference-design-documents-for-QN9021/m-p/464763#M782 hanfengwang 2016-03-10T19:03:15Z Re: Where to find SDK and reference design documents for QN9021 https://community.nxp.com/t5/Wireless-MCU/Where-to-find-SDK-and-reference-design-documents-for-QN9021/m-p/464764#M783 <HTML><HEAD></HEAD><BODY><P>Hi Hanfeng, i have the same questions, did you get any response or solved this?<BR />Actually i'm using the QN9020 SDK but i can't find some definitions.<BR /><BR />Best regards</P></BODY></HTML> Mon, 31 Jul 2017 19:01:29 GMT https://community.nxp.com/t5/Wireless-MCU/Where-to-find-SDK-and-reference-design-documents-for-QN9021/m-p/464764#M783 alexishernandez 2017-07-31T19:01:29Z
