Hi there.
I am needing to use the zed-f9r for a gps project, but need to use the 04B version as it has railway capabilities for dead reckoning. When would this be available? Thanks so much.
I have tried to get the dead reckoning working in a car and on a bicycle without any luck, but was running it a lot on a train with no luck either, so any and all suggestions to that would be welcome.
Did sparkfun sell the 04B version? I am not sure.
Hi @blade_790 - Welcome! Generally speaking, the -XX# delineates the firmware that is running on the ZED-F9R so that manufacturers can ‘pick’ or lock in a firmware for their build, but it’s just the firmware that is pre-installed and can be changed via firmware update. We have sold many variants of the ZED-F9R over the years, starting with -00B. I think we’re shipping -02B but I need to double check. You can purchase the breakout board and upgrade the firmware to HPS 1.30 making it a functional equivalent to the -04B.
Hi - have you had any luck with the dead reckoning? Care to share any lessons learned? I’ve implemented a wheel tick sensor on a bike, but I am unsure if my tick count messages are being used.
Try running through our guide (if you have the pHAT it is a bit further down, see the ToC on the right side) that covers how to wire up the encoders/enable the wheel ticks
Hi,
The ZED‑F9R 04B firmware isn’t publicly available yet, contacting u‑blox is your best bet.
For dead reckoning, make sure the IMU is calibrated and motion settings match your vehicle; trains and bikes need careful tuning.
