north central Ohio | Found thread from back in March or April about this board https://www.u-blox.com/en/product/c099-f9p-application-board and wondered if anyone got it programed to work well? I would like to use it on an Ag leader integra running an ontrac 3 and maybe a tile plow with intellislope if it seems accurate enough. Would be using ohio cors with lances ntrip. Lost link to thread and can’t find it now. Was a couple pages worth of guys trying to get it to work. Thought it could be a good farm stem project for the kids home learning this year too. Thanks Greg |

NE Indiana | I have four (4) units up and running well. I have one (1) setup as a base station feeding corrections to two (2) separate rovers. Both rovers are supplying RTK to Ag Leader Versas and Ontrac 2+. I also have one (1) setup as a staking tool with corrections coming from the Indiana CORs network for a general contractor colleague. All seem to be reliable and accurate! Each of these are the sparkfun RTK2 board with the ZED F9P (https://www.sparkfun.com/products/16481). I do also have one of the C099 application boards that you have linked. I've played with it a bit but do not have it up and running in a specific application. The C099 is a better deal in my opinion vs. the sparkfun board as it comes with the onboard bluetooth, wifi, and an L1/L2 antenna. The sparkfun board is essentially the board only and requires soldering headers to begin using the ports. The C099 essentially gives you everything needed to get up and running out of the box. These would be great for a farm STEM project! |

39.48, -82.98 | Do you have any photos showing your installations, from power source to antenna? I can think of many applications where these would work great. |

NE Indiana | I attached two photos of the boxes I made. One is my rover and the other is my base station. For the rover I'm taking power from the versa and stepping the voltage down to the necessary 3.3v required for the sparkfun RTK board. I'm inputting corrections via serial port and then exporting NMEA via serial port to the versa. I wired the box so it was a drop in replacement for the Ag Leader 2500 that was used previously. For the antenna I used an SMA to TNC connector so that I could utilize standard RG58 coaxial cable and connectors similar to other Ag GPS manufacturers. I am then using an L1/L2 + glonass antenna similar to the one at the following link (https://www.sparkfun.com/products/17587).

Coles County, Illinois | I've gotten the C099 working reliably as a base. It supplies corrections via SNIP to RTK2GO. I've gotten a RTK lock several times using the Lefebure Bluetooth App. When I tried to send RS232 data to an Envizio Pro II via a Max32 shield I bricked one of the C099 boards. I suspect somehow 5 volts got to the 3.3 V section. I ordered another C099 but harvest prep became the priority and I haven't got back to it. One thing with the Rover side I could get the Lefebure to attach to the Bluetooth side and the F9P to output NMEA data but getting the correction data from the Bluetooth side to the F9P side was unreliable. I'd get it working and cycle power and not get it back.
SparkFun has a new module that is interesting. If I'm reading the documentation right each time it's powered up it downloads the configuration to the module. It has bluetooth and appears there is a command line interface to store configuration data. I'm going to wait and see how this goes as I think I can use a parmi to get the data to the Envizio Pro or maybe thru a Qwiic device. |

39.48, -82.98 | Nice looking project!
Does anyone know how well these inexpensive boards hold up to shock and vibration? |

|
north central Ohio | Thanks for the reply’s. Eric your stuff looks great wish I understood this stuff better. If I wanted to put together a rover and base like you have what are the components of each? Did they all come through sparkfun? |
|
| |
|
NE Indiana | Thanks! I have a rough list that I can clean up and email you. I purchased the majority of the items through sparkfun and Amazon. |
|
| |
|
39.48, -82.98 | Can you copy me on that list?

Thanks! |

Westport, IN | I ran my last spring and fall with zero issues. I am using Lance's app and Indiana CORS.
The GPS has been on my cab top since May. It still works like it should.
I need a picture of the final product.
I bought the proper plug and mine is fully interchangeable with a 1600 smart receiver. I left the 1600 in my cab all spring in case I needed to switch back quickly. I never needed to though.

north central Ohio | Thanks Andy that looks great. What are the extra two boards that you added and are you using the receiver that came with the c099? Looks like one board is for serial output of rx tx and is the other a power supply board? Thanks Greg

Westport, IN | Herbie,
It may be bricked, but try a full reboot first.
I used a rs232 shield and it plugs into uart 1. Uart 1 seemed to be used for ic2 USB and communicating with the Odin radio.
This must run fast. 2,xxx,xxx baud or it boggs down the communication channel and appears bricked. You can try to set baud rate up on UART 1 and keep clicking send until it changes. You might get lucky.
So in my shield i bent the connector pins for the uart 1 in the converter board and soldered them to the pins connected to uart 2. Then set UART 2 to 115k to talk to ag leader.

Westport, IN | The other is a Arduino Uno.
It is for the radar emulator for my monitors.
I used that feature on the 1600.
It connects to f9p via ic2 and outputs a square wave at 41 Hz per mile per hour.

East Central, Nebraska | great work. i am sitting here all winter playing with this stuff. i have all kinds of projects in mind using arduino type cellular boards to try and automate/monitor functions on my farm to make the day go easier. i have read a lot about the ublox rtk but they haven't caught my eye as much as the other things i have rattling around in my head. these pictures sure motivate a person though.
my problem is that i really really like buying all the sensors and boards i can get my hands on for prototyping/tinkering but never actually complete a project. i need about 1 -2 more snowstorms to maybe have a completed project.
once again great work.

NE Indiana | I finally got around to emailing out the component list. Let me know if you did not receive it. |

39.48, -82.98 | Don't see it yet. [email protected] |

| I would be interested in the Uno code. People on the AgOpenGPS forum are looking for that kind of output for their monitors.

NE Ohio | I've been using the C099 for 2 years are my GPS input to AgOpenGPS. I've done all my planting with this and am happy with it. Using Ohio CORS as the correction, feeding it into the computer via a hotspot. Overall, I think the F9p is a solid low-Cost RTK solution. I connect to it via USB to feed the signals into a PC. Can't help on what's required to feed into an AgLeader. |

north central Ohio | Thanks for reply. Did you have any issues getting it to connect to your computer. It says it automatically downloads drives to computer when plugged in but can’t get it download. Shows f9p and odin with warning symbols under drives. Rod maker sent me a link with manual download of drive which I can get the f9p but can’t figure out the odin. How many com ports do you have? Thanks Greg |

Westport, IN | There is a USB hub in the board.
I had to look under device manager and get com ports.
Then play with baud rates.
My first board, had to use Windows 7 for Odin and Windows 10 for tbe f9p, or vise versa.
My second one the windows 10 worked for both.
Look into the baud rate of UART 1.
I have to run this connection fast. I think the UART 1 is the entire communication on the board, or at least influenced
other communications. I2C, USB, Odin, SPI, and UART 1. This would influence USB hub as well.
So to prevent bottlenecking it needs to run fast. I think 460k maybe more.
I then set UART 2 to 115k and send it to the guidance.
