BLEConsole

Windows command-line tool for interacting with Bluetooth LE devices

alt text

Requirements:

Windows 10, BT 4.0 adapter

Console commands:

  • help, ? : show help information

  • quit, q : quit from application

  • list, ls [w] : show available BLE devices

  • open or <#> : connect to BLE device

  • timeout : show/change connection timeout, default value is 3 sec

  • delay : pause execution for a certain number of milliseconds

  • close : disconnect from currently connected device

  • stat, st : shows current BLE device status

  • print, p <text&vars>* : prints text and variables to stdout, where are variables are:

    • %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
  • format [data_format], fmt : show/change display format, can be ASCII/UTF8/Dec/Hex/Bin

  • set <service_name> or <#> : set current service (for read/write operations)

  • read, r ** : read value from specific characteristic

  • write, w ** : write value to specific characteristic

  • subs ** : subscribe to value change for specific characteristic

  • unsubs ** [all] : unsubscribe from value change for specific characteristic or unsubs all for all

  • wait : wait seconds for notification event on value change (you must be subscribed, see above)

  • foreach [device_mask] : starts devices enumerating loop

  • endfor : end foreach loop

  • if : start conditional block dependent on function returning w/o error

    • elif : another conditionals block
    • else : if condition == false block
  • endif : end conditional block

    * you can also use standard C language string formating characters like \t, \n etc.

    ** could be "service/characteristic", or just a char name or # (for selected service)

Example of usage:

Lookup, connect and print all BLE devices names

BLEConsole.exe < cmd.txt, where is cmd.txt is a simple text file with content:

// Loop for each device
foreach 

	// Connect and if successfull
	if open $
		
		//Read first characteristic of first service
		read #0/#0
		
		// Close connection to device
		close
	endif
	
endfor
  • Blank/empty lines are ignored.
  • Comments can be added by preceding them with //

Below is an example of interactive use of the BLEConsole:

You can use BT name or # or address provided by list command. For example, run BLEConsole, type ls and it should list available BT devices, like

BLE: ls
#    Address           Name
#00: 85:41:35:3f:d6:8a TOZO-S2
#01: 65:b3:6e:8d:ba:f4 F2
#02: e4:98:bb:5f:80:53 LEDnetWF02004100000

Note: The list consists of devices that Windows has seen in the past time. Not all devices may be available at this moment.

Than use command open #1 or open TOZO-S2 or open 85:41:35:3f:d6:8a to connect to the device. (you can also use partial name, like TOZ if no more BLE devices with that name exist)

BLE: open #1
Connecting to TOZO-S2.
Found 3 services:
#00: GenericAccess
#01: GenericAttribute
#02: 2800

The open command will automatically list the available services on the device. Now you can set active service and list it's characteristics, by issuing command set #0

BLE: set #0
Selected service GenericAccess.
#00: DeviceName RW
#01: Appearance R
#02: PeripheralPreferredConnectionParameters    R
#03: 10918      R

Now you can read or write characteristics of the active service.

Read a characteristic by # or name, like read #0

BLE: read #0
TOZO-S2

Write a characteristic by # or name, like write #0 value

BLE: write #0 123

If you already knew your service name/#, you can avoid previous step and read characteristic after successful connection to BLE device, like read #1/#0

Data will be interpreted in the selected format Here we select hexadecimal as the format for both sending and receiving.

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

You can also directly write a value to a known service/characteristic. For example here we write an (hexadecimal) array of data to service (0xFFFF) / characteristic (0xFF01)

BLE: write 0xFFFF/0xFF01 00 04 80 00 00 0d 0e 0b 3b 23 00 00 00 00
