8. GPS Interoperability
8.1 AT*EENMEA NMEA (GPS) Mode on UART2
This command enables transmission of NMEA commands from
UART1 to UART2 and vice versa. The module acts as a transparent link
between the GPS device connected to UART2 and the application
communicating with it on UART1.
When the application sends the command AT*EENMEA=2 the module
is able to handle both AT and NMEA commands simultaneously. If the
OK response is received the application can start handling both NMEA
and AT commands. Otherwise the response ERROR is returned.
In the mode with simultaneous AT and NMEA commands, <CR> is
required after each NMEA command and after the last AT command
before the new NMEA. NMEA commands must start with a $. All
NMEA commands are forwarded to UART2. All NMEA responses
from UART2 are displayed as responses to UART1 along with AT
responses.
By sending AT*EENMEA=0, the application ends AT and NMEA
commands, simultaneous handling mode. It sends OK, and then returns
to AT mode.
The port rate of UART1 for NMEA commands can be controlled using
the AT*NMPR command.
