Setting up an Access point

Hello,

I've started a project where I'd like to setup a Bananapi M5 with two wifi adapters to use in hotel room for example. So one wifi adapter will connect to the hotel  wifi, and the other will be in access point mode with dhcp for my devices to connect to.

I think the proper terminology is AP-STA.

So I have purchased one Comfast CF-953AX which uses the mt7921au chipset (0e8d:7961) to test in access point mode as it supports this:

Supported interface modes:
		 * managed
		 * AP
		 * AP/VLAN
		 * monitor
		 * P2P-client
		 * P2P-GO

The issue I have come across is the hostapd fails to start:

nl80211: Failed to start radar detection: -22 (Invalid argument)

I think I've tracked it down to the wifi region not being set:

sudo iw reg get
global
country 00: DFS-UNSET
	(2402 - 2472 @ 40), (6, 20), (N/A)
	(2457 - 2482 @ 20), (6, 20), (N/A), AUTO-BW, PASSIVE-SCAN
	(2474 - 2494 @ 20), (6, 20), (N/A), NO-OFDM, PASSIVE-SCAN
	(5170 - 5250 @ 80), (6, 20), (N/A), AUTO-BW, PASSIVE-SCAN
	(5250 - 5330 @ 80), (6, 20), (0 ms), DFS, AUTO-BW, PASSIVE-SCAN
	(5490 - 5730 @ 160), (6, 20), (0 ms), DFS, PASSIVE-SCAN
	(5735 - 5835 @ 80), (6, 20), (N/A), PASSIVE-SCAN
	(57240 - 63720 @ 2160), (N/A, 0), (N/A)

sudo iw reg reload
command failed: No data available (-61)

..and you cannot set it, I think this post may explain it better than me:

Is there a way to set the wifi region?

Thanks
