How to set wifi(CYW43455) as AP mode in imx8mn EVK

[JimmyYu]

Hi ,

I try to set my imx8mn EVK wifi as AP mode with following commands, but it can not work. How to do it? Does imx8mn support this operation?

root@imx8mnevk:~# 

root@imx8mnevk:~# iwconfig --help

Usage: iwconfig [interface]

                interface essid {NNN|any|on|off}

                interface mode {managed|ad-hoc|master|...}

                interface freq N.NNN[k|M|G]

                interface channel N

                interface bit {N[k|M|G]|auto|fixed}

                interface rate {N[k|M|G]|auto|fixed}

                interface enc {NNNN-NNNN|off}

                interface key {NNNN-NNNN|off}

                interface power {period N|timeout N|saving N|off}

                interface nickname NNN

                interface nwid {NN|on|off}

                interface ap {N|off|auto}

                interface txpower {NmW|NdBm|off|auto}

                interface sens N

                interface retry {limit N|lifetime N}

                interface rts {N|auto|fixed|off}

                interface frag {N|auto|fixed|off}

                interface modulation {11g|11a|CCK|OFDMg|...}

Hi JimmyYu,

Are you using the onboard Wi-Fi module? The i.MX 8MNano EVK comes with the Murata 1MW module on board. If this is the case, you can refer to this link: https://community.murata.com/s/article/Problem-Need-to-Set-Up-Concurrent-STA-and-AP. It points to a Murata Technical forum blog on concurrent AP+STA operation. You can find the steps to set up an SoftAP there. Hope this helps.

Best regards

Hi JimmyYu

one can try suggestions provided in sect.4.13.7 Configuring WLAN from User Space

i.MX Linux Reference Manual​

and WiFi Manual from link:
