HL8548-G GPS problem with UDP transmition

Hello everyone!
I’m having trouble with a HL8548 -G , I have set to NMEA messages ( GGA and RMC only ) be sent by I2C . Everything works fine until I try to send data via UDP.
The current firmware version is: HL8548-G 5.5.14.0 (RHL85xx.5.5.14.0.201502091756.x6250_1) which was updated via AirVantage.
To see what happens, I forward incoming data from I2C to the UART of the microcontroller I’m using.
What happens is that messages arrive every 1 second totally different from what they should be.
Example:

$GPGGA,164603.0009.739.7S,051307130713071.6,42.442.442.460

Hope somebody can help me.

Thankyou in advance!

Hi,
You mean to say you were getting NMEA frames till you send some data via UDP? So both UDP and GPS are not working together? what kind of data you send?

Hi Alex,

The problem was on the uart driver of the microcontroller. Thank you so much for you reply.
