5.2.3.1. Write BT MAC address to driver fake map:
EFuse offset address :
BT MAC address
0x30
Table 16: Bluetooth MAC address offset in eFuse
Example : To write RTL8822CE BT MAC address to driver fake map.
(Ex : MAC Addr. = 00E04CAABBCC)
rtwpriv wlan0 efuse_set btwfake, 30,CCBBAA4CE000
5.2.3.2. Write thermal value to driver fake map
EFuse offset address : Refer to 7.2. : Bluetooth eFuse definition about calibrates of Tx power.
BT thermal meter : 0x28C[7:0]
rtwpriv wlan0 efuse_set btwfake,28c,thermal_valu (Hex)
Example : If BT thermal value = 80
rtwpriv wlan0 efuse_set btwfake, 28c,50
5.2.3.3. Write Tx gain/Flatness/LBT calibration value to driver fake map
EFuse offset address :
Refer to 7.2. : Bluetooth eFuse definition about calibrates of Tx power
Tx gain K valid bit = 0x278[1].
Tx flatness K valid bit = 0x278[2].
LBT valid bit = 0x278[5]
Tx gain K result saves to 0x279[7:0].
Tx Flatness K result saves to 0x27A[7:0]~0x27B[7:0].
