# uPyble



[![PyPI version](https://badge.fury.io/py/upyble.svg)](https://badge.fury.io/py/upyble)[![PyPI license](https://img.shields.io/pypi/l/ansicolortags.svg)](https://pypi.python.org/pypi/ansicolortags/)



### Command line tool for Bluetooth Low Energy  devices



**uPyble** is intended to be a command line tool [upydev-like](https://github.com/Carglglz/upydev/) to make easier the development, prototyping and testing process of devices based on boards running *MicroPython with **Bluetooth Low Energy** capabilities.



\*( Any other BLE device should work as well)



⚠️ ***Keep in mind that this project is in ALPHA state, sometimes, some commands may not work/return anything*** ⚠️



### Features:



* Command line wireless communication/control of MicroPython/other devices.

* Custom commands to automate communication/control

* Command line autocompletion

* Terminal BLE SHELL-REPL 🔸🔺

* Custom DFU Profile (`dfu_target.py` in profiles) and dfu commands to send scripts through BLE.



🔸 (REPL works,  but some SHELL commands are still under development)



🔺 There is a limit in the amount of output it can produce, so long lists or `cat` a big file will freeze the BLE SHELL-REPL and possibly the device, which makes a reset almost inevitable.



------



### Getting Started



To use Terminal BLE SHELL-REPL :



First be sure that the **BLE REPL daemon is enabled** and running:



* 1) Put `ble_advertising.py` ,`ble_uart_peripheral.py` and `ble_uart_repl.py` in the device



* 2) Add these lines to `main.py`:

  

     ```python

     import ble_uart_repl

     ble_uart_repl.start()

     ```



*These scripts are in upybleutils directory. (Originals from [MicroPython repo bluetooth examples](https://github.com/micropython/micropython/tree/master/examples/bluetooth))*



#### Installing :



`$ pip install upyble` or ``$ pip install --upgrade upyble`` to update to the last version available



#### Finding BLE devices:



Use `$ upyble scan` or `$ upyble tscan` for table output format.



```

$ upyble tscan

Scanning...

Scanning...

BLE device/s found: 1

==============================================================================

        NAME         |                   UUID                   | RSSI (dBm) |

 esp32-30aea4233564  |   9998175F-9A91-4CA2-B5EA-482AFC3453B9   |   -68.0    |

```



#### Create a configuration file:



\*upyble will use local working directory configuration unless it does not find any or manually indicated with `-g` option.



- To save configuration in working directory: `$ upyble config -t [UPYDEVICE UUID]`

  

  e.g:

  

  `$ upyble config -t 9998175F-9A91-4CA2-B5EA-482AFC3453B9 `

* To save configuration globally use -g flag: `$ upyble config -t [UPYDEVICE UUID]  -g`

  

  e.g.

  

  `$ upyble config -t 9998175F-9A91-4CA2-B5EA-482AFC3453B9 -g `

  

  \* Be aware that some devices may generate random UUID every a couple of minutes, so this won't be useful in those cases.



------



### uPyble Usage:



Usage:



`$ upyble [Mode] [options]`



This means that if the first argument is not a Mode keyword it assumes it is a 'raw' upy command to send to the upy device



##### Help: `$ upyble -h`



------



#### uPyble Mode/Tools:



- **`upyble check`**: to check local machine Bluetooth characterisctics

- **`upyble config`**: save upy device settings (*see `-t`, `-g`)*, so the target uuid argument wont be required any more

- **`upyble scan`**: to scan for BLE devices (*see `-n` for max number of scans)*

- **`upyble tscan`**: to scan for BLE devices, results with table format

- **`upyble sconf`**: to scan and configure a device that matches a name *`-d [NAME]`*

- **`upyble get_services`**: to get services of a device, use *`-r`* to read them and *`-mdata`* to see available metadata

- **`upyble get_stag`**: to get service tag from a service code, use *`-scode`* to indicate the code

- **`upyble get_scode`**: to get service code from a service tag, use *`-stag`* to indicate the tag

- **`upyble get_ctag`**: to get characteristic tag from characteristic code, use *`-ccode`* to indicate the code

- **`upyble get_ccode`**: to get characteristic code from a characteristic tag, use *`-ctag`* to indicate the tag

- **`upyble get_aptag`**: to get appearance tag from an appearance code, use *`-apcode`* to indicate the code

- **`upyble get_apcode`**: to get appearance code from an appearance tag, use *`-aptag`* to indicate the tag

- **`upyble get_mtag`:** to get manufacturer tag from manufacturer code, use *`-mcode`* to indicate the code

- **`upyble get_mcode`**: to get manufacturer code from a manufacturer tag, use *`-mtag`* to indicate the tag

- **`upyble cmdata`**: to get characteristic metadata (name, type, uuid, unit, format, notes...). (Not all characteristics are available yet), Use *`-c`* option to indicate characteristic or *`-c all`* to see all that are available. Use *`-xml`* to see the xml file instead.

- **`upyble cmdata_t`**: get_cmdata in table format.

- **`upyble dmdata `**:  to get descriptor metadata (Name, uuid, format...). Use *`-desc`* option to indicate a descriptor or  *`-desc all`* to see all that are available.

- **`upyble follow`**:   to read from a service (see *`-s`,* *` -c`* , *` -tm`*) , e.g : `upyble follow -s "Battery Service" `, will read all readable characteristics, or use  *` -c`*  to indicate a specific one/group. e.g:  `upyble follow -s "Battery Service" -c "Battery Level"`. This mode autodetects format and unit from characteristic metadata

- **`upyble rfollow`**:   to read from a service (see *`-s`,* *` -c`* , *` -tm`*, *`-u`* , *`fmt`* and  *`-x`*) , e.g : `upyble follow -s "Battery Service" `, will read all readable characteristics, or use  *` -c`*  to indicate a specific one/group. e.g:  `upyble follow -s "Battery Service" -c "Battery Level"`

- **`upyble see`**: to get specific info about a devices group use `-G` option as `see -G [GROUP NAME]`

- **`upyble brepl`**: to enter the BLE SHELL-REPL

- **`upyble ble@[DEVICE]`**: to access brepl in a 'ssh' style command if a device is stored in a global group called `UPYBLE_G` (this needs to be created first doing e.g. `$ upyble make_group -g -f UPYBLE_G -devs foo_device UUID`) The device can be accessed as `$ upyble ble@foo_device` or redirect any command as e.g. `$ upyble get_services -@foo_device`.

- **`upyble make_group`**: to make a group of boards to send commands to. Use -f for the name  of the group and -devs option to indicate a name and uuid of each board. (To store the group settings globally use -g option)

- **`upyble mg_group`**: to manage a group of boards to send commands to. Use -G for the name of the group and -add option to add devices (indicate a name and uuid of each board) or -rm to remove devices (indicated by name)

#### Examples: 



##### 	Follow the Battery Level and Temperature (cpu) of an Esp32.



​	This needs `ble_batt_temp.py` in the device. (See [upybleutils](https://github.com/Carglglz/upyble/tree/master/upybleutils))



​	In the device REPL do:



```python

>>> import ble_batt_temp

>>> ble_batt_temp.ble_batt.start_batt_bg()

```



Now in local Shell/Terminal:



1. Scan and configure device:



   ```bash

   $ upyble scan

   Scanning...

   Scanning...

   BLE device/s found: 1

   NAME: esp32-batt-temp, UUID: 9998175F-9A91-4CA2-B5EA-482AFC3453B9, RSSI: -59.0 dBm, Services: Environmental Sensing

   

   $ upyble config -t 9998175F-9A91-4CA2-B5EA-482AFC3453B9 -g

   upyble device settings saved globally!

   ```



   



2. Follow services
