$ python helper/ble-autoconnect.py -h usage: ble-autoconnect.py Service to automatically connect with devices that get available.
#Serial port emulator mac serial#
This makes it also possible to add ble module to create a wireless serial connection with existing hard/software.Īs mentioned before, the start might fail because the UUID is not in the list, then you can manually specify the correct write characteristic UUID like this:
#Serial port emulator mac Pc#
Same in the other direction, everything that the BLE module receives on the RX pin gets transmitted to the PC and shows up in the virtual serial port.
#Serial port emulator mac software#
The software acts as transparent bridge, everything that is sent to that virtual port gets transmitted to the BLE module and comes out of the TX pin there. does not matter, it will work with any value (settings are ignored, because it is only virtual). Now it is possible to use any serial monitor program, just connect to that port, baud rate etc. On Windows it uses the port pair created in the setup described above, this does not dynamically change and endpoint is always COM9 if you use the default script. In addition it automatically creates a symlink to /tmp/ttyBLE, so you can easily access it always on the same file, the default can be changed with the -p/ -port option. It uses the same mechanism on macOS, just the path is slightly different, in the format /dev/ttys000. This log shows a successful start on Linux, the virtual serial port was opened on /dev/pts/8, the number at the end changes, depending on how many pseudo terminals are already open on the system. Only the device address is always required:
Works only in combination with -l (default: False)
#Serial port emulator mac Bluetooth#
$ ble_serial -h usage: _main_.py -d DEVICE [-t Restrict transfer direction on bluetooth: read only (ro), read+write (rw), write only (wo) (default: rw) -l FILENAME, -log FILENAME Enable optional logging of all bluetooth traffic to file (default: None) -b, -binary Log data as raw binary, disable transformation to hex. Some other chips split it up, for example (this time on macOS with device ID): This module handles both directions through the same characteristic. Same procedure with the read characteristic, here you have to actually look for notify or indicate, that is how the receiving side is informed about new data in BLE. We are searching for a characteristic that allows writing = sending to the device, the only candidate in here is 0000ffe1-0000-1000-8000-00805f9b34fb (spoiler: a HM-11 module again). The ones belows the first service starting with 00002 are not interesting in this case, because they are standard values (for example the device name), if you want to know more look at this list.Īfter the UUID, handle and type the permissions are listed in.
Now the interesting parts are the characteristics, grouped into services.
