Hi, I have a Rock Pi 4B and trying to enable Monitor Mode on the onboard WiFi. According to this article it should work - RockPi4-Monitor-Mode The file download link is broken so was advised to use this one - https://github.com/radxa/rkwifibt/blob/master/brcm_tools/dhd_priv.c However when running the command - gcc dhd_priv.c -o dhd_priv I just get loads of errors. Has anyone managed to use monitor mode with the built in WiFi, or could possibly help to resolve all the error messages you get
