Once SendTxData function is called in "I-CUBE-LRWAN 2.0.0", it is called continuously.

The content of the function is simply putting data in the buffer and sending it.Even if the function is called once, it sends data 2 to 4 times.However, looking at the logs from the LORA gateway, they are sending data continuously.I'm not sure why th...

STM32WL55 does not receive uart input after a certain amount of time passes after sending RF periodically

Hi I am testing with STM32WL55I programed that MCU transmitted LoRa signal periodically and transmitted data via uart1 periodically.At first, MCU can recieve data via uart1.After a certain amount of time, MCU can't transmitted some bytes via uart1 on...

MLPF-WB55-02E3 connection to STM32WB55V WLCSP_100.

I have some questions on the response here:https://community.st.com/s/global-search/MLPF-WB55-02E3?t=1636577804470The response references MLPF-WB55-01E3 but I think it should be MLPF-WB55-02E3 for the WLCSP_100 package. Can you confirm the 65 ohm im...

How to reduce provisioning time and error for multiple unprovision device in BLE Mesh network?

Hello ST,I am using STM32WB55 board to establish mesh network between four node. Duration of provisioning from provision node taking long time (>25 sec ) and some time my command was correct " atep prvn0 2".. even UART is showing process is complete ...

Resolved! Read STM32WLE5C8U6 & STM32WLE4CCU6 UID

Hi,I'm working on the two MCU's STM32WLE5C8U6 & STM32WLE4CCU6 and I need to know the UID in order to indentify each of the products.In the doc it's written that both have UID but there is no address to read them.What I'm missing ?Best regards,

Where can I find API PHY_802.14.5 for STM32WB?

Hi,I am using STM32WB55 to develop a PHY 802.15.4 application with custom MAC. I found only the Phy_802_15_4_Cli example, but there are ASCII like commands. Can you provide byte oriented commands for working with PHY?

Sending BLE message data via UART

I am attempting to send a file via BLE (Windows app -> STM32WB55), I've found that the ACI_GATT_ATTRIBUTE_MODIFIED_VSEVT_CODE event is called whenever a packet is received by the board however I am unable to find where the actual packet data is store...

Count on Tim2 going past ARR?

I have a simple example where I take an A/D sample from a pot every 15ms. I then modify CCR1-4 on both TIM2 and TIM1 AS WELL AS ARR registers on TIM2 and TIM1. ARR is updated with a value and ALL CCRx are updated with that value - #define. I notic...

STM32WB10CC antenna connection shorted to GND.

For the new STM32WB10CC chip, there is no specification on default state of the RF pin, however, it should not be shorted to GND. Hardware has been verified with high confidence that short is not due to physical issues, is software short to GND on RF...

Resolved! Ask for AN5156 Layout recommendations's origin Altium PCB file?

Hi, I recently read the AN5165——Development of RF hardware using STM32WB microcontrollers，and the page25~page27 show the STM32WB55's reference design.But I didn't find the file on the offical website.Could you please share the files named:MB1427A---U...
