problem with receiving data (ble-serial)

[Hayatache]

hey !
is there another way to read what we receive from bluetooth than asyncio.gather( )?
or is that a way to choose when we receive ?
(when I use it, I can either receive the information only once and i can run the rest of my code, or I can't run the rest of my code and i receive only the data from the ble)

There are many ways to run tasks together, asyncio.gather() is just one of them. This is not specific for ble-serial, but about python asyncio is general, I would suggest reading up on that. Also it is only needed to keep the BLE_interface.send_loop() running, that works on the send buffer.
Receiving is just a regular (non async) callback function you pass into BLE_interface.set_receiver(). You can not choose when to receive by default, because a connected device can send data at any time. It is possible to implement a buffer though, for a example that can hold a single response, take a look here: #72 (comment)
If you need to buffer multiple messages before your code can process it, then you could use asyncio.Queue, that is how it works in the command line tool with serialport emulation.
