Resolved! How to detect STM32 CubeMX Programmer from my application

I am developing an application on the Seeed Lora-E5 module, which contains an STM32WLE5.Currently I am programming the device via the SWD interface, but for future firmware updates I want to use the UART, (this UART is available externally through a ...

What can prevent entering STOP mode? (STM32WB)

After some activity using BLE in the background and UART as well as some EXTI on application side, the consumption jumps from 2,4µA to 4mA, so obviously I have a wakelock. If I hotplug to the system afterwards, I can see in PWR_EXTSCR that Stop mode ...

STM32WB5MMG UART receive interrupt doesn't work

I'm using a STM32WB5MMG chip and I'm trying to receive data with the HAL_UART_Receive_IT() function. But for some reason the HAL_UART_RxCpltCallback function never gets called. Receiving data with blocking mode works, but with an interrupt it doesn't...

Hi, I have STM32WB55. It has 1 UART and 1 low-power Uart (lpuart). I can see Zigbee uses lpuart, as there is no UART left, is it possible to use on STM32WB55 Nucleo board Zigbee and sensor whit SDI12 protocol?

Hi, I have STM32WB55.It has 1 UART and 1 low-power Uart (lpuart). And I have SDI12 sensor.I have successfully read whit lpuart SDI12 protocol sensor. But now I want to use ZigBee to send data that I read from the sensor to the Zigbee coordinator. I c...

I have the following code where the variable string takes on the float value toPC correctly. I step into the HAL_UART_Transmit_IT and step over all the assignments and all looks fine yet I never see the TDR register update with the first value. Fur...

I am using a NUCLEO-WL55JC1 and the LoRaWAN_End_Node example. I want to add USART1 to the example, so that I can forward the UART data over LoRa. The problem is that the interrupts for USART1 never trigger if the LoRaWAN process is also running.

If I comment out "MX_LoRaWAN_Process();" in main, then the USART1 interrupts trigger as they normally would. Could anyone offer some advice of how to add USART1 to the example?Kind regards

Hello everyone, I am encountering an issue with UART1 while using STM32WL for LoRa Communication with SubGHz_Phy_Per and STM32WL-SubGHz-PhyBasic-Tx-Rx examples from the STM32 Github.

In my application, I receive a message from LoRa and intend to transmit it via UART1 which is set to PA9 and PA10. However, when I check the UART RX using a logic analyzer, I do not receive anything.I have tested the UART1 alone in a simple project, ...
