Unable to Connect and share the file using Wi-Fi Direct for IMX8MP board using Realtek(RTL8822BU)

Yamini · ‎01-28-2024

Hi,
I recently worked on IMX8MP Phytec PhyBoard Pollux to bring up Wi-Fi using Realtek Chipset on LINUX Platform, i made the board to act as a Host (Access point) and Station (client) using Hostapd. conf and wpa_supplicant.conf files respectively and can share the internet from IMX8MP Board to external Connected devices(Clients).
Currently, I am working on Wi-Fi Direct sharing (peer-to-peer communication) on IMX8MP Board using Realtek Chipset(RTL8822BU) by using the same wpa_supplicant.conf file and wpa_cli.

By using the following commands, I can scan and list out nearby Wi-Fi Direct devices and connect to the particular Wi-Fi device using Wi-Fi Direct(P2P). But, the established connection is getting disconnected within a few seconds and I am unable to share the information/data between two connected devices.

p2p_find
p2p_peers
p2p_connect <dev mac Address> <pbc/pin>

Here, is the issue I am facing while trying to connect and share the data.

Hi @Yamini!

Thank you for contacting NXP Support!

Sorry, our source code is for our EVK boards and only works for our Wifi-Modules, and other modules are not implemented.

Please try to use the Phytec source code:

https://www.phytec.eu/en/bsp-download/?bsp=BSP-Android-NXP-i.MX8MP-ALPHA1

If the problem persists try to contact Phytec support.

Best Regards!
Chavira
