I have a number of legacy Ardupilot boards, in fact 5x 168 and 3x 328.  So I would like to ask for your help to locate the right version for 168 and 328.  Last I did the test, none of them worked well in Auto mode.  So I think I like to do it again.  Please advice.

Best regards,

Peter

Daft Q? chaps...

Where in 2.7.1 can we switch off stick mixing in auto?

i know wher it is in 2.6.4 (my fave code!) but cannot find it in this version..

Looking forward to anyones thought?

(Anyway we need to liven up the 'Legacy' section of this forum!

regards,

Mike.

google sirfdemo and there are links for downloading the program.  Probably not the best solution since you need a seperate TTL/serial connection and that can be involved.  I got one from sparkfun.com and my computer has a serial port, but I also needed a voltage regulator.

@Harry, yes you are right. I should weight for over a week to bring it back to the default NMEA mode. But the code should bring it to the Sirf mode any time. However, in my case it has never been in Sirf mode. Let me wait for a week and then see starting from NMEA.

I could not understand the serial connection, SirfDemo, usglobesat thing? Any link about this?

If you could get a serial connection, then you could download SirfDemo from usglobalsat and put in whatever mode and speed you want.  That's assuming there isnt something wrong, but you have gotten a fix indication.  Have you tried just letting it sit for a week, not just a few days?  A few days might clear it, but a week guarantees it is clear. Then start again where you are now by trying NMEA first.

Tried by enabling the EM406 as NMEA by uncommenting it in the foder GPS_NMEA.pde in code 2.7.1. To avoid verifying/compiling errors I had to comment out the LOCOSYS related lines just before the EM406 related lines. Waiting for 40 minutes in the open could not get any thing on the serial monitor for GPS debug test. So yet no success.

One thing I learnt from the literature that WAAS is not used out of the USA. Those who are using the code out of the USA should disable it in the defines.h folder. Is there any thing elase to be done with the code? Otherwise there should be some problem with the GPS. Should I go for the MT GPS?

That's the section.  Worth a try.  Keep trying things.

@ Harry, you mean the following one, OK I will try that but first I will try to get it into binary mode by disabling the WAAS in defines.h (my location is out of US, so WAAS is not available), thanks.

 

/* EM406 example init
 Serial.begin(4800); //Universal Sincronus Asyncronus Receiveing Transmiting
 delay(1000);
 Serial.print(SIRF_BAUD_RATE_9600);
 
 Serial.begin(9600);
 delay(1000);
 
 Serial.print(GSV_OFF);
 Serial.print(GSA_OFF);
 
 #if USE_WAAS == 1
 Serial.print(WAAS_ON);
 #else
 Serial.print(WAAS_OFF);
 #endif*/

Anwar, here's something to try to run it in NMEA.  In the 2.7.1 sketch, the tab labeled GPS_NMEA the section for EM406 initialization has been commented out.  Try uncommenting and see if it will connect.

Hi all, any one please help me. My GPS EM406 is not getting into binary mode. My board is 328 (without shield) and I have FMA XY sensor (without Z sensor). I have tried all codes upto 2.7.1 but the GPS is not getting into binary mode. Having GPS Protocol -1, i.e. no GPS, everyting works fine but when I attach the GPS to the board, servos do not respond to radio except in Manual mode and do not respond to XY sensor at all. The LED on the GPS itself turns on when the board is powered and starts blinking after a while if I take it out of the house.

If the EM406 is NMEA by default then why can't we use the NMEA option provided in the code? Or otherwise please let me know how to turn it into binary mode?
