GS407 (GPS-11466) Serial garbage readings

Postby dvdvck » Tue Apr 16, 2013 9:16 am

Hi there,

I can't get a legible reading from this unit.

I connect to it using putty confiured as were stated:
9600
8 bits
1 bit stop
no parity
no flow control

then I have this output:
Code: Select all
                               §§§§§§«åë·q_qY}§}§ë·q_qYS§                                         §§§
§§§«åë·q_qY}§}§§§§§§£§S§c«åë                                     £
                                                    £   §§§§§§«åë·q_qY}§}§[}m姫[}må_qY}§}§[}må§S§§§§§§§§§§c«såë·q_SWq§§§§§§§§§c«åë·q_qq§§§§§§«ë·q_qY}§}§
£§S§§§§§§§§§§c«uåë·q_SWq§§§§§§§§§c«åë·q_qq}§£§§§§§§§   £
                                                    §§§£§§«åë·q_qY
}§}§               åë·q_SWq§§§§§§§§§c«åë·q_qq}§£§§§§§§§
[}m壧S§§§§§§§§§§c«åë·q_SWq§§§§§§§§§c«åë·q_qq}§£§§§§§§§

[}må           åë·q_SWq§§§§§§§§§c«åë·q_qq}§£§§§§§§§
£§S§§§§§§§§§§c«


Then I tried using every single speed from 2400 to 115200 and all of it outputs garbage.

I used u-blox center but It doesnt recognize the message. :(

I am interfacing the tx/rx with a Logic Level Converter https://www.sparkfun.com/products/8745.

Someone can point what am I doing wrong?
Thanks for your time

The issue was an inappropiate Logic level converter.

It works with some serial level converter https://www.sparkfun.com/products/9873
