Hi all.

I am facing a problem with "GTop PA6B (MTK3329 Chipset)" GPS Module.

- I gave power 4.8V from USB

- STATUS PIN is always HIGH. I connected a LED which is always ON. But as per datasheet, before 2D/3D-Fix the LED should Blink (STATUS PIN should give a Square Pulse with 1sec Width) and after 3D-Fix LED should be OFF (STATUS PIN LOW).

- I checked the GPS TX PIN (PIN9) with MAX232 Board, but no NMEA data I am getting. I am using 9600 Baud Rate (though I also tested 4800 and 115200 Baud).

Any advice. Do I need to do anything to get the NMEA Sentence? Is there any meaning of "STATUS LED always ON"?

Thanks in advance & Regards.
 

Hi,

I'm hitting the same problem... did you get a solution? Really appreciate it if you have any clues on this one.

Cheers
Tim
 

Thank you very much indeed, that was my mistake too... just waiting for it to get a fix now...
 

Hi.

Nice to know. Are you using PA6B? I used this before.

I am currently doing a project with PA6E.

Regards.
 

PA6B... aka cheap and cheerful from AliExpress (which is actually a good place to pick up cheap Chinese components if you don't mind a 3 week shipping delay, often cheaper than Ebay, equally lacking in documentation, but worth a look!). I got some ST7735 driven displays and some RFM22B radio RX/TX units from there too, and all for "throw away" amounts of money. It's not so distressing if you toast something when it's cheap... which was a lesson I learnt last month: Beer + wiring new toys (backwards) = stinky and annoying.
