Driver installation

Hi,

Does that board have a USB UART? I couldn't see one... 

Are you using a separate USB UART board/cable? If so, this isn't a Rohm semi issue, it's a USB UART driver issue.

You could try a different USB UART (some do not require drivers). Win 7 is so ancient, I can't recall what will and what won't work with it. You could also test your UART board with the Rohm module outside of the VM.

Dear R.Manu,

Thank you for your question to ROHM, we would like to suggest the following;

If you connect the BP359C & BP35C5-T01 to another Windows PC (NOT virtual machine)

and the driver installs automatically, then this problem is probably on your virtual machine.

Please check your virtual machine settings and the following tips on driver installation.

Device driver cannot be installed:

• • Are you installing with administrator ID?

    Please try manually specifying the driver folder from Device Manager and installing it.

    Please check the followings:

          [Computer Management] => [System Tools] => [Event Viewer] => [Windows Logs]

    If you have 3rd party security software installed, please try disabling it. 

Try also the solution for "Windows found drivers for your device but encountered an error while attempting to install them." as follows:

We hope that this helps,

Hi,

I have been trying to communicate with BP359C & BP35C5-T01(Slave) from STM32F103RCT6(Master) through UART without RTC & CTS but when a query "BAUD" is sent from STM32. At the receiver of STM32 both query and response are received together like "BAUD BAUD 11520" whereas the response should be "BAUD 115200". 

Note: UART connection from through-hole group 1

Thank you

Hi, R. Manu,

Thank you for your question.

The BP35C5 is enabled for echo back by default.

Echo back can be disabled with "echo" command

>echo 0 //turn echo back off

By doing this, STM32 will only receive BP35C5 responses.

We trust that this answers your question.

Kindest regards,
