CC2340R5: HCI command for BLE controller example project

Tool/software:

hi Expert,

Can I use BLUEZ hcitool to set and read the tx power with hci command to BLE_controller example project?

There is BLE specific HCI commands below for read and set tx power as below. Can it support in BLE_controller example project?

BT Commands for LE	OGF	OCF	Opcode
Read Transmit Power Level	3	45	0x0C2D

Vendor Specific Command	OGF	CSG	CMD	Opcode
HCI_EXT_SetTxPowerCmd	63	0	1	0xFC01
HCI_EXT_SetMaxDtmTxPowerCmd	63	0	17	0xFC11

How can I send the hcitool command? Below is correct?

root@OpenWrt:/tmp# hcitool -i hci0 cmd 0x03 0x002D
< HCI Command: ogf 0x03, ocf 0x002d, plen 0
> HCI Event: 0x0e plen 7
01 2D 0C 00 02 02 00
root@OpenWrt:/tmp#
root@OpenWrt:/tmp# hcitool -i hci0 cmd 0x3F 0x0011 0x00 0x02
< HCI Command: ogf 0x3f, ocf 0x0011, plen 2
00 02
> HCI Event: 0x0e plen 4
01 11 FC 01
root@OpenWrt:/tmp#

root@OpenWrt:/tmp# hcitool -i hci0 cmd 0x03 0x002D
< HCI Command: ogf 0x03, ocf 0x002d, plen 0

Hello Frank,

You can use the controller only solution with a host app such as BTool or BlueZ (linux). What is the purpose, is it RF/BLE testing or a host-controller full solution?

You can try the commands using BTool: C:\ti\simplelink_lowpower_f3_sdk_9_11_00_18\tools\ble\btool

You can also simply use a script to transmit the TX dump from a host (PC for example) to the controller, like:

import serial
import time

# === CONFIGURE UART ===
UART_PORT = "COM177"  # Adjust based on your system (e.g., COM3 on Windows)
BAUD_RATE = 115200 # High baud rate for fast communication

# Open UART connection
uart = serial.Serial(UART_PORT, BAUD_RATE)

def send_hci_command(command_hex):
    """Send an HCI command to the CC23xx over UART."""
    command_bytes = bytes.fromhex(command_hex)
    uart.write(command_bytes)
    time.sleep(0.05)
    response = uart.read(uart.in_waiting)
    print(f"HCI Response: {response.hex()}")

# === SETUP HCI TEST ===
def test_hci_ble():
    print("Testing HCI Commands")

    # Clear Adv Sets

    send_hci_command("01 02 20 00")

    # BD_ADDR = "DD:9A:78:56:34:12"

    send_hci_command("01 39 20 06 01 01 00 00 00 00")

    # Send_HCI_EXT_NumComplPktsLimitCmd 2, 0
    #send_hci_command("01 1f fc 02 01 00")

    # Send_HCI_LE_Read_Buffer_Size
    send_hci_command("01 02 20 00")

    time.sleep(4)

    #HCI_LE_SetPhy
    send_hci_command("01 32 20 07 00 00 00 02 02 00 00")

    while (1):
        time.sleep(0)
        send_hci_command("02 00 00 78 00 00 11 22 33 44 00 11 22 33 44 00 11 22 33 44 00 11 22 33 44 00 11 22 33 44 00 11 22 33 44")
