Follow steps below to change baudrate of UART1 to 112500

Open Ucenter and connect to gps NEO-9M

../_images/changebaurateto115200.png

On Toolbar, choose View -> Generation 9 Configuration View to open configuration window

../_images/configurationwindow.png

Then choose Advanced Configuration

../_images/advancedconfig.png

Choose CFG-UART1 -> CFG-UART1-BAUDRATE

../_images/changeuart1baudrate.png

In value field change 38400 to 115200, then select Set in RAM, Set in BBR and Set in Flash. Then select Send config changes

Follow steps below to change baudrate of UART1 to 112500

Copy and paste commands to send box of Hercules and tick HEX box.

../_images/sendbox.png

Then select send sequently and have the result below

../_images/sendconfigresult.png

Note

If you change baudrate first, you will have to change baudrate of Hercules (or Uart of MCU) before do any other changes.

All steps above will be applied for all your wanted configuration

You can also send 3 layer commands in once

  • Set baudrate 115200
