KW35 Bluetooth authentication modulation wave testing problem

renlei — Sun, 08 Dec 2019 06:32:19 GMT

When we certified the MKW35A512, the wireless council required testing of single carrier and modulated waves at 2.402GHZ and 2.480GHZ transmission frequencies.The single carrier test can be passed, but the modulation wave test waveform is not consistent with the wireless specification.We conducted debugging according to the software "tera term" provided by NXP, and adopted the standard routine "frdmkw36_wireless_examples_genfsk_conn_test_freertos". The modulation wave was tested by wireless commissioning, and we transmitted the modulation wave according to the steps of 3, 4 and 5 in the debugging software, but the resulting waveform was different from the standard modulation wave shape.Please refer to the attachment for details.

Hi Ken,

Please get in contact with your local support for a better understanding of your issue.

Let me know if you still have issues with the modulation.

Regards,

Mario
