6.2 TX Power Using HCI Commands

If Calibrator tool has not already been set up, please navigate to the Getting Started with Calibrator Tool section before continuing.

To prepare the device for testing, type the following lines:

cd /usr/share/cc33xx/
./set_power_mode.sh 0
calibrator wlan0 cc33xx_plt ble_plt
calibrator wlan0 plt power_mode on
calibrator wlan0 cc33xx_plt tune_channel 8 0 3
calibrator wlan0 cc33xx_plt set_manual_calib -tx 1 -rx 1
calibrator wlan0 cc33xx_plt tune_channel 6 0 0
bluetoothctl power on
calibrator wlan0 plt power_mode off
ifconfig wlan0 down

Next, configure the parameters as desired and run the test. The commands below show an example flow at TX power 20dBm, on channel 10, with packet length 255, packet pattern PRBS9 and Phy Rate 1Mbps (LE 1M). For more information, reference the BLE RF Testing Via Linux Driver Guide found in the CC33xx SDK:

hcitool cmd 3F 11 0x6                #Set TX power
hcitool cmd 08 34 0xB 0xFF 0x00 0x01 #Set CHANNEL, PACKET LENGTH, PACKET PATTERN, PHY RATE. Start TX
hcitool cmd 08 1F                    #Stop TX

Configure the VSA so that TX Power can be viewed. After initiating the Start TX HCI command, run continuous analysis on the VSA to capture data.
