Hi,
With a BeagleBone Green Wireless running Debian 10 and linux kernel 4.19, I'm unable to start simultaneously AP and mesh roles (in the same frequency/channel).
For individual AP or Mesh roles I have no problem.
Here is my hostapd config file:
##### hostapd configuration file interface=SoftAp0 logger_syslog=-1 logger_syslog_level=2 ctrl_interface=/run/hostapd ##### IEEE 802.11 related configuration ssid=BeagleBone country_code=PT ieee80211d=1 hw_mode=g channel=6 max_num_sta=10 macaddr_acl=0 auth_algs=1 wmm_enabled=1 ##### IEEE 802.11n related configuration ieee80211n=1 ##### WPA/IEEE 802.11i configuration wpa=2 wpa_passphrase=BeagleBone wpa_key_mgmt=WPA-PSK rsn_pairwise=CCMP
and here is my wpa_supplicant config file:
#### wpa_supplicant configuration file for Mesh (802.11s) networking
ctrl_interface=/run/wpa_supplicant
max_peer_links=10
mesh_max_inactivity=30
country=PT
p2p_disabled=1
network={
ssid="BoneMesh"
mode=5
frequency=2437
key_mgmt=NONE
# key_mgmt=SAE
# psk="BoneMesh"
}
If I start first the mesh interface, whn I try to start the AP I get this error:
debian@beaglebone:~$ sudo hostapd /etc/hostapd.conf Configuration file: /etc/hostapd.conf SoftAp0: interface state UNINITIALIZED->COUNTRY_UPDATE Using interface SoftAp0 with hwaddr fc:69:47:32:59:23 and ssid "BeagleBone" Failed to set beacon parameters Interface initialization failed SoftAp0: interface state COUNTRY_UPDATE->DISABLED SoftAp0: AP-DISABLED SoftAp0: Unable to setup interface.

If I start hostapd in debug mode I see more details on the errors:
-- nl80211: assocresp_ies - hexdump(len=10): 7f 08 04 00 00 02 00 00 00 40 nl80211: Beacon set failed: -16 (Device or resource busy) Failed to set beacon parameters SoftAp0: Flushing old station entries -- nl80211: send_frame -> send_frame_cmd nl80211: Frame command failed: ret=-16 (Device or resource busy) (freq=2437 wait=0) wpa_driver_nl80211_set_key: ifindex=8 (SoftAp0) alg=0 addr=(nil) key_idx=0 set_tx=0 seq_len=0 key_len=0 --
If I start first the AP, when I try to start the mesh interface I get this error:
debian@beaglebone:~$ sudo wpa_supplicant -i mesh0 -c /etc/wpa_supplicant/mesh.conf Successfully initialized wpa_supplicant Using interface mesh0 with hwaddr 0c:1c:57:92:5c:82 and ssid "" mesh0: interface state UNINITIALIZED->ENABLED mesh0: AP-ENABLED mesh0: joining mesh BoneMesh mesh0: mesh join error=-16 mesh0: Could not join mesh
Is there any known limitation to work simultaneous AP and Mesh in kernel 4.19?
Is there some extra configuration that needs to be setup in hostapd and/or wpa_supplicant for this to work?
Best regards,
José Gonçalves
