Thanks. With only firmware update mower work (no change in config file or other), so certainly initial config survive. It mow actualy, so i need to check the behaviour under some particular position to see if it's better. Next step is the update of the base station , and change in the sunray...

After updating the firmware to 1.32 , do i need to also upload a configuration file or it's already done by sunray firmware when starting with the config.h value ? #define GPS_CONFIG true // configure GPS receiver (recommended - requires GPS wire fix above!

Thanks .Now It's compile without error. Now i need to check if it's better than old version.

Hi . I try to test this solution but it fail to compile , maybe i have trouble to understand or translate !!! Can you share directly the Ublox folder inside a zip file ?

Many Thanks. I use the Ardusimple board ship by marotronics and never change firmware ,it's work on first connection. I have sometime (near wall or under tree) a GPS jump from fix to invalide and fix again directly in 2 secondes ??? In the ardusimple Site i see a new release of firmware that...

HI. I use a LR kit with 2 rover. Something strange is that the satellite in view qty are not the same for the 2 rovers when they are at the same location (+/- 1 meter) I have thought that one of the 2 number is the amount of satellite that the base station received ? So way this difference ?

I don t remember exactly when, but i see this after the update for retry touch in docking station. Are you really sûre that it is not drive motor at vers low PWM

When a command is send to sunray firmware (Over BT by sunray app or UART by Pi) one answer is send as feedback by sunray firmware So PI need to read and decode the feedback Y3, sentense (it's power off request) BUT in the original firmware when Sunray app send AT+Y3 the PCB immediatly power...

It's ok on P17 to flash ACGM4, but you need the extra capacitor. Now you need to read the AT+Y3 command feedback on cassandra for the undervoltage protection or send it to power off Simply change sunray as follow : Into amrobotdriver.cpp add a 30 second delay before power off to leave time...

@EinEinfach I have change some part in the sunray firmware to do that correctly and wait 20 second between the shutdown command and the effective power off of the PCB. Did you manage the correct PI shutdown without changing sunray firmware ??

Yes with DUE, do not forget to swap Rx Tx between the 2 board. For your over voltage issue: A crash of the DC/DC step-down is certainly the problem, but on some config with big brushless Mow motor it's also possible on an emergency brake to have a feedback voltage on the 24V line . What kind on...

Certainly Yes . The main goal is to have a full autonomous robot mower with the largest possible mowing area using scheduler. In all case In the last Azuritber firmware (i don't remenber if i include this in the DUE code, but it's into the teensy one) : if there is no timer active ,then the PCB...

Hi. For pcb1.3 , so certainly 1.4 also. Relay is not powered when mowing to avoid unusefull power consumption At end of charging if mower stay in dock pcb use the charger power and not the battery power so no issue to leave mower into station for many week. Certainly your battery setting is not...

Azuritber is not RTK (Only odometry and IMU) and run on DUE. Azuritber wiki is only to see the vision part working on a connected raspberry pi: https://wiki.ardumower.de/index.php?title=AzuritBer_Pi_Firmware_(English) take a look at Expérimental AI Vision with Tensorflow part. For 4 wheel...

Take a look here for 5 motor management and raspberry pi connections.It s sunray version https://forum.ardumower.de/threads/sunray-and-tactile-screen-pi-app.25304/#post-63055 The vision part Was ok on olber version (raspbian) but need Some change on ai picamera part for bulleyes You can see it...

Yes of course;), but the working mode is totaly différent .What about the power consumption ? Maybe @Fürst Ruprecht can give more info about that

Wheel ---》stepper motor ??? Why not brushless one ?

In réalité Compass (using magnetic earth ) can't work inside a mower (simply test with your smartphone and a Compass APP and you are going to see the stupid result when moving the phone around the mower). I use into all my code only GYRO and ACCEL based on gravity and they work everywhere...

Hardware is the PCB1.3 and robomow RL1000 platform (see post on RL1000 rebuild https://forum.ardumower.de/threads/robomow-rl1000-rebuild.23679/ ) with 3 INA226 sensor for mow motor sense . PiSunray don't work with standard sunray version. Into config.h you can deactivate the INA226 sense...
