Hello again,

Ok, the issue is a small bug in the script itself. The probe itself is not closed correctly when done, which means that you should add probe.close() right before print("Done"). See attached script:

from pynrfjprog import HighLevel
api = HighLevel.API()
api.open()
snr = api.get_connected_probes()
for s in snr:
    probe = HighLevel.IPCDFUProbe(api, s, HighLevel.CoProcessor.CP_MODEM)
    probe.program("mfw_nrf9160_1.2.0.zip")
    probe.verify("mfw_nrf9160_1.2.0.zip")
    probe.close()
    print("Done")
 
api.close()

This worked for me at least. Let me know how it works for you.

Kind regards,
Øyvind

Hello Aswin,

Yes, I'm seeing the same issue here as well. It looks like a bug that has been introduced with the latest versions of pynrjprog. I will forward to our developers and get back to you as soon as I have an answer from them.
