Hi,
on a Mac, I am trying to install credentials to a nRF9160 using device_credentials_installer.py.
The nRF9160 is running the AT Host application. I can connect to it via the nRF Serial Terminal using /dev/cu.usbserial-0001 (115200/8/N/1) and send AT commands and receive results.
Then I disconnect and close the nRF Serial Terminal and run
$ python3 device_credentials_installer.py -v --port /dev/cu.usbserial-0001 <parameters>
I always get
OS detect: Linux=False, MacOS=True, Windows=False
Opening port /dev/cu.usbserial-0001 as generic device...
Disabling LTE and GNSS...
-> AT+CFUN=4
Serial timeout
Unable to communicate
I also tried a small python test application and it was able to communicate with the nRF9160 just fine. But device_credentials_installer.py seems to have a problem.
Any ideas are appreciated.
Edit: I switched to using the modem shell and RTT as the communications method and that works fine. So there appears to be a bug in with the serial communication in device_credentials_installer.py.
Thanks,
