Where can I see the TX2 supported country code? And the applicable channel?
What is Hostapd for Hot Spot Configuration?
I did not see the AP according to this configuration
interface=wlan0
driver=nl80211
hw_mode=a
channel=36
ieee80211ac=1
ssid=WLAN-TEST
auth_algs=1
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
wpa_passphrase=12345678
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
After changing the configuration or not
interface=wlan0
ssid=Calmcar
hw_mode=a
channel=36
wpa=2
wpa_passphrase=12345678
wpa_key_mgmt=WPA-PSK
driver=nl80211
ieee80211n=1
ieee80211ac=1
wpa_pairwise=TKIP
rsn_pairwise=CCMP
auth_algs=1

Calmcar-Bao,
If you are using PX2, please move the Drive forum board.
As for country code for tx2, please refer to wifi compliance document:
https://developer.nvidia.com/embedded/dlc/Jetson-TX1-OEM-Wireless-Compliance-Guide
My fault.
Has been switching between the two platforms recently.
This problem is seen in TX2.
TX2 hotspot configuration can say it? I can’t open the hotspot according to the above configuration
Please try to use different channels which are valid in your country.
