But we can=E2=80=99t bring up 2 radio interfaces concurrently, once we bri= ng up the 5G interface at first then get the =E2=80=9Cdevice busy=E2=80=9D err= or message when bring up 2.4G radio. But WCN6856 is a DBDC chip, suppose I can bring up two radios in the same time for AP mode. Is it the limitation of driver or HW ? And how do I fix this issue = ? Thanks for your time.
