How to determine the reg domain and country code that are currently set in the 60-series module?

60 Series SOM60-2230C60-SIPT

Answer

When you issue the following command on an embedded Linux system with mounted debugfs and correctly integrated 60-series radio, you, for example get the below information:

 # cat /sys/class/ieee80211/phyX/device/lrd/info  Driver name : lrdmwl Chip type   : 88W8997-SDIO HW  version : 7 FW  version : 5.5.46.5 DRV version : 9.32.0.13 OTP version : 1 OTP num mac : 3 Radio Type  : SU MAC address : c0:ee:40:50:2a:70 Region code : 0x10 (0x10) Country code: 'US' ('US') TX antenna  : 2 RX antenna  : 2

The country/region code on the left is the current code that is used by the system at that moment, whereas the one in parentheses is what is currently in OTP.

The only time they might not match is when using Advanced World Mode (AWM).

The used region codes are:

 0x00: WW (World Wide) 0x10: FCC 0x20: IC 0x30: ETSI 0x31: KCC 0x32: AU 0x40: JP 0x50: CN

"phyX" in above command will have to be replaced with the actual phy your module is known to your system. e.g. phy0, phy1, phy2, phy3,...
