hi everyone i am using ublox neo-5q GPS module. i am trying to configure it using ublox protocol. for that i am sending the messages to the receiver according to the protocol but i am not able to configure it. i am using LPC2103 Controller for that. and GPS is interfaced with UART1 of the controller. anybody is having any idea regarding the receiver configuration of this module.
The external device - any external device - neither knows nor cares what you use to send stuff to it.
The only thing that matters is that whatever you send is in accordance with the device's specifications.
Do you have something else that can send this protocol, and is known to work? If so, compare what that's sending against what you are sending - and spot the difference(s)!
ya andy
i am fully agree with u that whatever u send it must be under device's specification.
see my problem is that by default GPS is sending all the information such as GGA,GLL,GSA,RMC,VTG,GSA in NMEA format. but i need only RMC. for that reason i want to configure the GPS module so that it will output only RMC data.
now to configure this i am using a proprietary protocol ublox but still i am getting all the messages. i am not able solve the problem.
do u have any idea about ublox protocol?
Clearly, you need to ask u-blox about that - it has nothing to do with Keil or the LPC2103 !
