How to query if joulescope device is already open

Technical Discussion

Hi @jj110 - Your Joulescopes keep the path from Current+ to Current- enabled by default when you close the Joulescope. Here is code to demonstrate:

import joulescope
import time

device = joulescope.scan_require_one()
for i in range(10):
    print('open')
    with device:
        time.sleep(1)
    print('close')
    time.sleep(1)

I used an LED and power supply set to 10 mA limit to check that the LED remained illuminated through these cycles using both a JS110 and JS220.

Here is my platform information:

I am not sure exactly what you are seeing. Can you provide runnable code that demonstrates the problem?
