EM7455, Deactivate Low-Power-Mode

[Barton]

@fs1

Thank you for this post, I can’t get into the “engenering” mode with at!unlock, I think this may be a challegene-response sequence. As it changes with every at!unlock? command.

AT!OPENLOCK?
6FF19EEBB325DB2D
OK
AT!OPENLOCK="CFE6B46892423A75"
ERROR

For EM7305, I use a Response Generator to AT!OPENLOCK by this link:
github.com/bkerler/SierraWirelessGen

For EM7455 he can not work … The algorithm has changed …
