I have a Sierra MC7455 on Sprint network. I am trying to figure out how to query PRL and run update on it.
I found that there is a command “at$PRL?” which will return to me “$PRL: NOT IMPLEMENTED”.
Does anybody know how to implement PRL on this module and the command to update it? I have read that “+PRL=2” can be used to run PRL update but I have been unable to get this to work due to the error above.
Any guidance would be greatly appreciated!
Thank you in advance.
