NUCLEO-WB09KE board USUART -> LPUART change fail

[JunkgyuHan]

Dear ST team.

(related :Re: UART of NUCLEO-WB09KE UART signal no found - STMicroelectronics Community)

I am testing with NUCLEO-WB09KE EVB

Started from the example code ; "BLE_Peripheral_Lite", which is using PB0/PA1 as usuart port

I can see the Uart output signal on MB1801, CN3.37.

Then I manipulate to code to use LPUART; PB4/PB5 [attached code: BLE_Peripheral_Lite_LPUART1_PB4PB5.zip]

But the result is, Uart output signal is still on MB1801, CN3.37(same PIN with USART).

Did I do something Wrong? or Missed something?

Please Help

Just as an aside, you need to configure your terminal so that it starts a new line (ie, does both LF and CR) when it receives a LF.

Then you won't get the lines disappearing off to the right - as they are in your screenshot.

@Andrew Neil Thank you for advice but this is not what I expected.

the code is based on the original example code. I tried to minimize the modification

[Andrew Neil]

I was talking about your terminal configuration - not modifying the software.

[JunkgyuHan]

@Andrew Neil  Oh. Okay I misunderstood. I changed the config

[Andrew Neil]

Have you tried a simple, basic example which just does output to the LPUART on PB4 & PB5 - nothing else ?

I would suggest that you do that first, to prove that you have basic connectivity.

Once you have that working as a reference, then you can look at how to merge it into the BLE application.
