HELP! I need to change my QRP Labs GY-GPSV3-NEO module, which has the UBlox NEO-7M-000 chip on it to 4800 baud,
Mike,
I do not know what module you are referring to.
I have just checked with a uBlox M7 and find I cannot get uCenter to permanently change the baud rate. After a cold start it goes to 9600.
I seem to remember I found that before...
It does save NMEA sentence configuration.
In the past I have used a backup battery which will save configurations.
Perhaps there is a uBlox group somewhere? Might give some clue.
Although others seem to have the problem
Maybe some things are stored on-chip, others in flash.

the old NMEA 0183 standard for the TinyTraker3 APRS units.
I can use the UBlox u-center25.03 and everything I receive and send from it appears to work, telling me that the RS232/TTL interfaces that I try are correct. However, going into Messages View - UBX - CFG - PRT - TragetUART1 (or any other) setting BAUDRATE to 4800 and hitting the Send button makes NO CHANGE (EVER). It stays at 9600 Baud!
Is there another way to try this and make the change permanent? Perhaps there is an inhibit connection on the chip? Or some sort of authorization command? Connecting a terminal program gives me the continuous GPS strings so the module is correctly putting out my location etc., so that part is also working fine (at 9600).
I appear to be stumped! Miniature GPS units running at 4800 Baud are pretty rare and I want to resurrect my Altoids Box Pocket Tracker with one to make it truly pocket size, again.
