Updating F9P firmware with RTKBase

[Stefal]

When a new firmware is available for the gnss receiver, it could be helpful to update it from RTKBase.

Problem: Currently, there is no Gnu/linux tool to flash a F9P

But there is a workaround:

⚠️ WARNING! DO THIS AT YOUR OWN RISK !

• Stop the main str2str service from the web interface or from a terminal with sudo systemctl stop str2str_tcp.service

• Open a serial to tcp connection with socat. My gnss receiver is on ttyACM0 so the command line is sudo socat tcp-listen:128,reuseaddr /dev/ttyACM0,b115200,raw,echo=0

• Open U-Center from another computer and create a network connection with the RTKBase ip address and port n°128

• Connect U-Center to your F9P with this network connection

• Open the U-Center Firmware update utility. Select the firmware and use these settings:

• Click on the "Go" button

• When the update is ok, the F9P will be disconnected, you will have to restart the sudo socat ... command on your base terminal. Then reconnect it in U-Center and check if the firmware version is correct (Message View -> UBX -> MON -> VER). Now you can disconnect U-Center

• With the new firmware the receiver use its default settings. To reconfigure it for RTKBase, launch rtkbase/tools/install.sh --detect-usb-gnss --configure-gnss

• When it's ok, enable back the service you need from the RTKBase web interface.
