Hello Howard!

Ah okey, I think I misunderstood what your issue was for a second. Sorry about that.

[quote user=""]One thing I also noticed is that the Bluegiga Bluetooth Low Energy dongle won't connect in the nRF Connect Bluetooth Low Energy app.[/quote]

Yes that is unfortunately not possible. Our nRF Connect applications unfortunately only work on our products, as they interface using our own protocol.

[quote user=""]Problem is I can't seem to figure out how to get data from the nRF52840 to the Python App. I'm sending a simple string from the nRF52840 when connected but bt_nus_send returns an error. [/quote]

That should be possible. What error message are you getting?

[quote user="GameCodingNinja"]Hard to make sense of it since it does way too much.[/quote]

Yeah, the pc_ble_driver_py might be a bit hard to get up to speed with, and unfortunately there aren't any tutorials for it yet as far as I know. You do have the examples though. If you'd prefer to use the Bluegiga one then that should work as well.

Best regards,

Elfving

So I've installed pc_ble_driver_py and setup my nRF52840 dev board as a Bluetooth dongle. I can scan and connect with it using the your Bluetooth Low Energy app in nRF Connect for Desktop.

I'm looking at the example Python code in the test folder included with your library. At this point I just want to scan and connect to our device that is using the nRF52840 chip. The code in the test folder way to verbose. Hard to make sense of it since it does way too much. Simple examples of small digestible chunks is the best way for people to come up to speed with your Python library. It also doesn't help that I've never used the unittest library and not sure what to do with it.

Any direction would be appreciated.

Not using your Python library, using bgapi Python package. Could you point me to your Python library and the Bluetooth dongle you suggest I should use?

Hello Howard!

I think the issue simply is that the python library we have only works for our own dongle, and not the Bluegiga. Are you using our python library?
