Overview:
• This message can be used to delete saved configuration to effectively revert them to
defaults.
• This message can delete saved configuration from the Flash configuration layer and the
BBR configuration layer. The changes won't be effective until these layers are loaded into
the RAM layer.
• This message is limited to containing a maximum of 64 keys up for deletion; i.e. N is a
maximum of 64.
• This message can be used multiple times with the result being managed within a
transaction.
• This message does not check if the resulting configuration is valid.
• See Receiver Configuration for details.
• See version 0 of UBX-CFG-VALDEL for simplified version of this message.
This message returns a UBX-ACK-NAK, cancels any started transaction, and no
configuration is applied:
• if any key within a transaction is unknown to the receiver FW
• if an invalid transaction state transition is requested
• if the layers bitfield changes within a transaction
