The ble_adapter.py read_req doesn't allow reading data > ATT MTU

[RyanLindemanCAE]

I am using the pc-ble-driver-py as a platform to test my BLE peripheral device. I need the ability to read characteristics which exceed the ATT MTU value. This is possible if an offset parameter is added to the read_req method found in ble_adapter.py and then using a similar algorithm to the following:

def read(self, uuid, base=None):
    # Use read_req to get first few bytes (offset=0)
    status, data = self._read_req(uuid, base=base)
    if not status:
        return None
    # If data filled maximum size allowed there might be more data
    elif len(data) == (self.att_mtu - 1):
        # Read more while status is OK and length is not 0
        message = []
        while status and len(data):
            if data:
                message.extend(data)
            status, data = self._read_req(uuid, offset=len(message), base=base)
    # Otherwise, just return the short data received
    else:
        return return data
    return message

def _read_req(self, uuid, offset=0, base=None):
    status, data = self.controller.adapter.read_req(self.conn_handle, BLEUUID(uuid, base=base), offset=offset)
    return status == BLEGattStatusCode.success, data

Thank you for merging my pull request that addresses this issue. Do you have a timeline when a release will be made that includes this fix?

The code was part of v0.14.2 that was released to pypi a while ago (Feb 14th), though it hadn't been released here on github until now. Closing the issue.
