Activating BLE

[poesel]

Hi,

I'm probably thick here but why does:

Code: Select all

from ubluetooth import BLE, UUID, FLAG_NOTIFY, FLAG_READ, FLAG_WRITE
ble = BLE
ble.active(True)

give me a 'TypeError: argument has wrong type'?
The firmware is from today. The example code does the very same - just in __init__ and it works so its not some hardware problem.

?

Thanks

Hi,

BLE is a type, so to construct an instance of it, you need to use BLE().

i.e.

Code: Select all

ble = BLE()
ble.active(True)

Which example were you looking at, happy to fix any mistakes or make it clearer.

There is no problem with an example. They work very well. It is only my lack of understanding of the details of Python...

I took the temperature example:

Code: Select all

...
class BLETemperature:
    def __init__(self, ble, name='mpy-temp'):
        self._ble = ble
        self._ble.active(True)
...

and didn't notice that you do just what you described here:

Code: Select all

...
def demo():
    ble = bluetooth.BLE()
    temp = BLETemperature(ble)
...

Being able to read helps a lot.

Thank you!
