All in One PCB

It doesn’t if the Uart1 is not correct, I had this same scenario a couple of weeks ago.

Yeah i upload and saved like 4 times still nothing

The configs are already at 460k. Make sure your antennas are in clear sky.
I assume you updated your F9P’s to version 1.32 before you loaded the configuration files

Yeah updated saved it and then configured then saved again for both f9p

The second time i configured the heading f9p i used a cofig that was 38400 and 1hz and the led turn on iven without any antena conected

Are in both f9p the uart1 and 2 460kbps.
Tried in a open space still no gps light I think I got gps



Try using a decent 12V power supply. You may be asking a bit much from the USB power.
Avoid chaining pigtails, every additional connector can weaken the antenna signal with up to 1 dB.
Check the F9P LED’s, they are telling you there is no GPS fix and no RTK. The PCB LED’s can be misleading. Are you using dual GPS or IMU for roll? (setting in AOG)

Well I think is the setting because I have got the to light up and
And I don’t know yet but at the moment the imu is showing front and back roll instead of left to right
and the only way that the pcb ligth turn on is if its on braudrate 38400

Would anyone in Canada have an extra board for the Standard F9P’s, preferably with the AMPSEAL connector?

Uart1 460,800

I’m not sure if both should be this, but definitely the right one (one closest to the Teensy).

If using dual f9p the antennae’s will be your IMU.
There is a setting in AOG to select/de-select this.

With dual the baud rates on the modules must match. Uart1 right and uart1 left set to 460k. Uart 2 should be 460k also unless you have an xbee radio on the F9P. Then 115k is used.
The F9p’s communicate with each other over the serial uarts, so they must be the same. The latest release of AOG requires the latest .ino loaded on the teensy and is set to 460k baud. So uart1 must be 460,800 baud on both F9P’s.

So plug it in the tractor the light still doesn’t turn on but I’m getting gps and rtk fix
Which way should the pcb face ?
And on agopen the tractor is going in an angle how do I set the two antennas ?





The ampseal connector should be facing backwards. Tap on the tractor icon to reset direction forward. You may want to enable reverse detection.

Like that.

Divide the distance between the antennas in half. And make this distance in the settings with an offset, with a minus sign.

Like this
They are 1.04
So -52

The tractor still is going in a angle in sted of straight

Try to enable single gps in the program

On single it goes straight

I’ve not used Dual, but was under the impression that AOG assumes you’ve centred the antenaes and offset is for if not centred.
@Renato looks like he has both antenae an equal distance from centre of tractor, so no offset required.

How many degrres is it off? It looks like you have the antennas mounted fairly well.
You can use heading offset(degees) to adjust it.
Right above dual as IMU.

it was of by 50 degrees but then i turn it of then back on and was only 10 so dont know whats going on
