Configuring Modes and Other Parameters for Wi-Fi and Bluetooth

You can set power levels of Bluetooth and Wi-Fi, as well as modes of operation and country code. Use /etc/default/rs9113  to configure parameters at boot time. See below for parameters with their usage and input values.

For several of the parameters, only one option is currently available. See below for details and refer to the example file at the bottom of the page.

NOTE: Do not insert spaces inside the commands especially around the equal sign. Otherwise, it may not work.

Default Parameters

From /etc/default/rs9113:

# Skip loading the RS9113 related drivers if
# set to zero.
#
RS9113_LOAD=1

RS9113_LOAD=1 enables the RS 9113 driver. To disable it, set it to zero:

RS9113_LOAD=0

# Parameters for rs9113 driver
#
# Enable Antenna Diversity (1)

The only option currently available for diversity is to disable it (set to 0):

RSI_ANTENNA_DIVERSITY=0

COEX Mode selection  

This variable selects the COEX_MODE for module operation. NOTE: Only specific options and combinations of functions operate on the device. Not all combinations are possible. Please refer to the table and read details below. Those not specified in the table are not supported.

# COEX_MODE options:
#               1    WLAN STATION /WIFI-Direct/WLAN PER
#               2    WLAN ACCESS POINT (including multiple APs on different VAPs or Virtual Access Points)
#               3    WLAN ACCESS POINT + STATION MODE (on multiple VAPs)
#               4    BT CLASSIC MODE/BT CLASSIC PERIPHERAL MODE
#               5    WLAN STATION + BT CLASSIC MODE
#               6    WLAN ACCESS POINT + BT CLASSIC MODE
#               8    BT LE MODE /BT LE PERIPHERAL MODE
#               9    WLAN STATION + BT LE MODE
#               12   BT CLASSIC + BT LE MODE
#               14   WLAN ACCESS POINT + BT CLASSIC MODE+ BT LE MODE

This example sets the mode to Bluetooth Classic (BT) mode:

COEX_MODE=5

RF Power Mode parameter

The RF Power Mode parameter sets the power mode at which the RF operates. It is applicable for each protocol. The default is 0x00 – For Both TX and RX High Power. The following are the possible configurable values:

# Power selection
#       0x00 - For Both TX and RX High Power
#       0x11 - For Both TX and RX Medium Power
#       0x22 - For Both TX and RX LOW Power
#       0x10 - For High Power TX and Medium RX Power
#       0x20 - For High Power TX and LOW RX Power
#       0x01 - For Medium TX and RX High Power
#       0x21 - For Medium Power TX and LOW RX Power
#       0x02 - For Low Power TX and RX High Power
#       0x12 - For LOW Power TX and Medium RX Power

This example sets the WLAN both the TX and RX for High Power:

WLAN_RF_PWR_MODE=0x00

This example does the same for Bluetooth:

BT_RF_PWR_MODE=0x00
# 0 - HIGH  POWER MODE
# 1 - MEDIUM POWER MODE
# 2 - LOW POWER MODE

This example sets the BT on high power mode:

BT_RF_TX_POWER_MODE=0

Country selection
This parameter sets the module in a specific country. This is set commonly across all protocols. The following country codes are applicable:

 # Country Selection
# 0 World Domain
# 840 US Domain Maps to US Region
# 276 Germany Maps to EU Region
# 392 Japan Maps to Japan Region
# from ISO 3166-1

This example sets the country code to World Domain:

SET_COUNTRY_CODE=0

Antenna selection

This variable selects the antenna used. Currently, only option 2 is available on the device.

2 – Select internal antenna
3 – Select external antenna

So the internal antenna should be defined as follows:

ANT_SEL_VAL=2

For onboard antenna, only option 1 is available:

ONBOARD_ANT_SEL=1

Example file for /etc/default/rs9113

# Skip loading the RS9113 related drivers if
# set to zero.
#
RS9113_LOAD=1

# Parameters for rs9113 driver
#
# Enable Antenna Diversity (1)
RSI_ANTENNA_DIVERSITY=0

# COEX_MODE options:
# 1 WLAN STATION /WIFI-Direct/WLAN PER
# 2 WLAN ACCESS POINT(including muliple APs on different vaps)
# 3 WLAN ACCESS POINT + STATION MODE(on multiple vaps)
# 4 BT CLASSIC MODE/BT CLASSIC PER MODE
# 5 WLAN STATION + BT CLASSIC MODE
# 6 WLAN ACCESS POINT + BT CLASSIC MODE
# 8 BT LE MODE /BT LE PER MODE
# 9 WLAN STATION + BT LE MODE
# 12 BT CLASSIC + BT LE MODE
# 14 WLAN ACCESS POINT + BT CLASSIC MODE+ BT LE MODE
COEX_MODE=3

# 0x20 - For High Power TX and LOW RX Power
# 0x01 - For Medium TX and RX High Power
# 0x21 - For Medium Power TX and LOW RX Power
# 0x02 - For Low Power TX and RX High Power
# 0x12 - For LOW Power TX and Medium RX Power
WLAN_RF_PWR_MODE=0x00
BT_RF_PWR_MODE=0x00
