wifidirectadvertisementpublisher can only create GROUP OWNER with 20MHZ bandwidth?

I'm developing a function for WIFIP2P connection on a mobile computer. When I set IsAutonomousGroupOwnerEnabled to true, it will create a GO that handles the same channel and bandwidth as the current WIFI connection. If the WIFI connected to the computer is 2.4G WIFI, it will appear The interference is relatively large, and the delay is serious. When I tried to set IsAutonomousGroupOwnerEnabled to false, let the computer create GO by negotiating NEO. It seems that the interference and delay problems have improved, but the bandwidth of the created GO has always been 20MHZ, it will not automatically follow the WIFI connected to the computer. Is there any way to control the GO channel and bandwidth?

May I know the OS of your mobile computer? In addition, could you please share a simple reproduced project for us to better investigating this issue?

It seems that there is no api to control the GO channel and bandwidth in Windows, maybe you could try to use Android apis to achieve.

but I found HUAWEI LATOP can control the GO channel and bandwidth in Windows , Their product which called Huawei Share is connected by WIFIP2P， and they control the GO channel and bandwidth in Windows very well, I thinks there must be some way to do this.
