Insatll from PyPi

MAX-BLE-HCI is hosted via PyPi and can be installed with the following command

pip install max-ble-hci

Installation from source

If you prefer to use the most up to date version, you can also install from source.

The intsall.sh or .bat are used to install the library into your Python site packages and be done as such.
On Linux or MacOS

sudo chmod +x install.sh
./install.sh

On Windows

install.bat

Basic Usage

The BLE-HCI is a mostly generic library, which is capable of driving any BLE devices which can communicate using the UART transport.

To use with Analog Devices, Inc. BLE capable MAX32 microcontrollers, please flash one of the following examples to the chip you are using

• MAX32655
• MAX32665
• MAX32690

If you have not yet set up an installation of the Analog-Devices-MSDK, please follow the instructions found here https://github.com/Analog-Devices-MSDK/msdk/tree/main
Once the board is flashed refer to the README in the example to configure your board.

Locate the serial port to which the HCI is connected to. If for example, your serial port is COM5, the following code would be used to reset the device.

from max_ble_hci import BleHci

port_name = "COM5"

hci = BleHci(port_name)
hci.reset()

Command Line Interface (CLI)

By defaults, the CLI capable of driving the BLE-HCI is installed as part of the package and can be accessed by running

max_ble_hci --version

The cli requires a serial port to connect the HCI to and is passed in through the command line. Once connected, you can type the help command as such, and begin to explore the CLI.
