22.5.1î™–î™–î™–î™–Description
Configures the network connection to a Multi GNSS Assistance (MGA) server. The configuration is saved in
NVM and applied at the next GNSS power cycle. The MGA server is accessed with the HTTP. This assistance
mode requires a packet data connection to exchange information with u-blox servers. By default, the cellular
module connects to u-blox' primary MGA server; if the connection fails then the cellular module connects to
u-blox' secondary MGA server. Authorization tokens are used as a means of authorizing access to the u-blox
services and for gathering anonymised statistics. To obtain a token customers should use the form in http://
www.u-blox.com/services-form.html. The set command registers a token for gathering assistance data from
MGA servers. Once a token is set it cannot be cleared so that registered hostnames in +UGAOP and +UGAOF
commands are discarded.
Setting up Internet connection and network registration is not part of this command and must be handled
by the user separately to this command.
