BLEConsole

Windows command-line tool for interacting with Bluetooth LE devices

Version 2.1 - Enhanced Pairing and Usability

New in v2.1:

• Smart Auto-Pairing: Automatic pairing when connecting with open device [pin]
• Interactive PIN Input: Support for devices that display random PIN (DisplayOnly IO capability)
• Endianness Control: New endian command for byte order (Little/Big Endian)
• Improved pair command: Direct PIN input (pair 123456), all pairing modes supported
• Improved unsubs command: Unsubscribe from specific characteristic or all at once
• Pairing Status Display: stat command shows pairing information
• Better Error Messages: Improved English and consistency across all commands

Previous in v2.0:

• Complete refactoring with Command Pattern architecture
• Descriptor support (read/write GATT descriptors)
• MTU information display
• Fast writes (WriteWithoutResponse via write -nr)
• Batch read operations (read-all)
• Device Information Service helper (device-info)
• Enhanced characteristic properties display

Requirements

Windows 10, BT 4.0 adapter

Console Commands

General Commands

• help, ?: show help information
• quit, q: quit from application
• list, ls [w]: show available BLE devices (w for wide format with full IDs)
• open <name|#|addr> [pin]: connect to BLE device, with optional pairing PIN
• close: disconnect from currently connected device
• stat, st: show current BLE device status and pairing information
• timeout <sec>: show/change connection timeout (default: 3 sec)
• delay <msec>: pause execution for a certain number of milliseconds

Data Format Commands

• format, fmt [format]: show/change display format (ASCII/UTF8/Dec/Hex/Bin)
• format_send, fmts [format]: show/change send data format
• format_rec, fmtr [format,...]: show/change received data format (comma-separated list)
• endian, bo [little|big]: show/change byte order for read/write operations

GATT Operations

• set <service_name|#>: set current service for read/write operations
• read, r <name>**: read value from characteristic
• read-all, ra [service]: read all characteristics in a service
• write, w [-nr] <name>** <value>: write value to characteristic (-nr for WriteWithoutResponse)
• subs <name>**: subscribe to value change notifications
• unsubs [<name>**|all]: unsubscribe from specific characteristic or all (default: all)
• wait: wait for notification event

Descriptor Commands

• desc <name>: list all descriptors for a characteristic
• read-desc, rd <char>/<desc>: read descriptor value
• write-desc, wd <char>/<desc> <value>: write descriptor value

Device Information

• mtu: show current MTU size
• device-info, di, info: read Device Information Service

Pairing Commands

• pair [<pin>]: pair with optional PIN
• pair mode=ProvidePin [pin]: pair with PIN (interactive if not provided)
• pair mode=ConfirmOnly: pair with confirmation only
• pair mode=DisplayPin: pair when device displays PIN
• pair mode=ConfirmPinMatch: pair with PIN matching confirmation
• unpair: unpair currently connected device

Scripting Commands

• print, p <text&vars>*: print text and variables to stdout
  • %id - Bluetooth device ID
  • %addr - device BT address
  • %mac - device MAC address
  • %name - device Bluetooth name
  • %stat - device connection status
  • %NOW, %now, %HH, %hh, %mm, %ss, %D, %d, %T, %t, %z - date/time variables
• foreach [device_mask]: start device enumeration loop
• endfor: end foreach loop
• if <cmd> <params>: start conditional block
• elif: alternative condition block
• else: else block
• endif: end conditional block

* You can use standard C escape characters like \t, \n etc.

** <name> can be "service/characteristic", characteristic name, or # index

Examples

Connect with PIN pairing

BLE: open ESP32_Device 123456
Connecting to ESP32_Device. It is not paired.
Attempting to pair with PIN...
Pairing successful.
Found 3 services:
#00: GenericAccess
#01: GenericAttribute
#02: Custom Service

Interactive PIN pairing (device displays PIN)

BLE: open MyDevice
Connecting to MyDevice. It is not paired.
Attempting to pair...
Device is displaying a PIN. Enter the PIN shown on the device:
PIN: 847293
Pairing successful.

Subscribe and unsubscribe

BLE: set #2
Selected service Custom Service.
#00: NotifyChar   N
#01: WriteChar    W

BLE: subs #0
Subscribed to characteristic NotifyChar (notify)

BLE: unsubs #0
Unsubscribed from NotifyChar.

BLE: unsubs
Unsubscribed from 0 characteristic(s).

Change byte order for numeric data

BLE: endian big
Byte order set to Big Endian.

BLE: format hex
Current send data format: Hex
Current received data format: Hex

BLE: read #0
hex:    00 01 02 03

Batch script example

// Loop through all devices
foreach

    // Connect and if successful
    if open $

        // Read device name
        read #0/#0

        // Close connection
        close
    endif

endfor

Notes

• Blank/empty lines in scripts are ignored
• Comments can be added with //
• Device list shows devices Windows has seen recently (not all may be currently available)
• You can use partial device names if unique (e.g., open ESP instead of open ESP32_Device)
