Hello,
For my project I am planning to use Sierra MC7455 module. I want to use the
module along with ConnMan & oFono.
The versions used are:
Connman: 1.34
Ofono: 1.20
Linux Kernel : 4.9.39
After plugging in the module I could see that the device getting attached and
the interface cdc-wdm0 is available. The log messages are as shown:

I tried to run the test scripts under ofono, but it doesn't able to identify
any modem devices. The log messages are as shown:
root@cl-som-imx7:/usr/lib/ofono/test# ./list-modems
root@cl-som-imx7:/usr/lib/ofono/test#
root@cl-som-imx7:/usr/lib/ofono/test# ./enable-modem
Traceback (most recent call last):
File "./enable-modem", line 14, in <module>
path = modems[0][0]
IndexError: list index out of range
root@cl-som-imx7:/usr/lib/ofono/test#
It would be great if you get help me in identifying the issue.
Mit freundlichen Gr??en / Best regards
