We are pleased to announce support for Raspbian Buster, available from our main repo. Just follow the instructions in “Getting Started” to get the zymkey host packages.
Please note that this has not been tested on the pi 4 yet.
Have you test on pi 4 ?
I have follow the : Getting started with my raspberry Pi 4 and Raspbian Buster Lite.
The Led blink slowly, but when i launch the script python, i have this error :
python /usr/local/share/zymkey/examples/zk_app_utils_test.py
Exception AssertionError: AssertionError(‘bad return code -1’,) in <bound method Zymkey.del of <zymkey.module.Zymkey object at 0xb67dbe10>> ignored
Testing data lock…
Traceback (most recent call last):
File “/usr/local/share/zymkey/examples/zk_app_utils_test.py”, line 6, in
dst = zymkey.client.lock(src)
AttributeError: ‘NoneType’ object has no attribute ‘lock’
Do you have any idea of the error ?
Hello,
We run Raspbian Buster Lite on a Pi 4. I know you say the LED was blinking slowly but the symptom you’re describing may happen if the binding has stopped. Can you post back the output from:
sudo systemctl status zkifc
I’d like to confirm that the zymkey interface service is active (running) at the time you see the Python script fail.
Also, is there anything else that may be contributing, like do you have any other HATs on your Pi?
Bob
Thanks for your answer !
My problem was that a stop button was configured on the GPIO3
