Hi all,

I've been trying to use the STM32WB55 Dev Kit and if I generate the project with the peramitirs below and then try to build the project I get this error;

*** Error Code ***
 
C:/Users/bryce/STM32CubeIDE/workspace_1.3.0/STM32WB55-MB1355C/Debug/../STM32_WPAN/App/app_thread.c:582: undefined reference to `MX_LPUART1_UART_Init'

I'm not too sure how to debug this, please could someone help me with debugging this issue.

I think its todo with the GUN not being able to see the Utilities folder?

*** Project Config ***
 
HSEM -> Active
 
RF -> Active
 
RTC -> Active
 
LpUart1 -> Mod -> Asynchronous
 
STM32_WPAN -> Thread -> Active
 
STM32_WPAN -> Thread -> Configuation (Tab) 
 
 HW UART -> CFG_HW_LPUART1_ENABLED -> Enable
 App Parameters -> CFG_CLI_UART -> hw_lpuart1
 
Clock Configuration -> Resolve Clock Issues

Thanks for looking into this and if you need anything Please let me know

Hi, I'm getting a very similar error while linking. Have you managed to solve it?

Found it. The generated code declares the UART init functions as static by default.

My difficulty isn't always with sampling the accelerometer. That works k. I can get uncooked statistics from it just excellent ammo. My trouble is that I'm now not able to set any of the unfastened-fall configuration bits.
