Hi, I'm trying to use for my project networkmanager. I've build image using yocto with nm v1.8.2. On my HW I'm using SDIO wifi chip (esp8089) which I can operate with wpa_supplicant and simple config file. When try to use it with networkmanager nmclo device show wlan0 as unavailable. When checked logs it seems that wpa_supplicant cannot bring interface up because somebody else is trying to do the same. I've added process name to kernel driver code (can be seen in kernel messages like: esp_op_add_interface interface 2 requested by - NetworkManager - 231). When looking through log it seems that nm is trying to add wireless interface but also wpa_supplicant which then driver refuse as max interfaces is 2 (also not sure what it means). Anything else I can check or how to workaround this probem? (when using raspbian wifi with nm works fine).
Hi, it seems the driver gets confused by the MAC address change: kernel: [ 9.476452] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready kernel: [ 9.482897] esp_op_add_interface interface 0 requested by - NetworkManager - 231 kernel: [ 9.490304] esp_op_add_interface STA kernel: [ 9.495224] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready NetworkManager[231]: <info> [1511649658.0166] device (wlan0): set-hw-addr: set MAC address to 26:2F:1A:C7:05:F4 (scanning) kernel: [ 9.504764] esp_op_add_interface interface 2 requested by - NetworkManager - 231 Perhaps you can try disabling the randomization of MAC address during scans; add the following to /etc/NetworkManager/NetworkManager.conf and restart the service.
