NUCLEO-WL33CC1 fails to connect after a succesfull programming
Hello allwe have recently recevied several NUCLEO-WL33CC1 boards, equipped with the brand new STM32WL33 wireless MCU.The problem we are facing is very strange: we can't connect to the board after some operation.we have created a new project with Cube...
Resolved! RTC current time in milliseconds (display in 6 byte hex)
Hello,I am using an STM32WB55 and am trying to figure out how to get the current time including milliseconds using an RTC and display that time in 6 byte hex format. I would most likely call the GetTime() based of a millisecond timer if that is the ...
Advice for Adding cellular connectivity
I have a dev_kit which I want to use to connect to a cellular network with LTE-M. But the example-file that they gave were a .bin file from XCUBE_CELLULAR for B-L462E-CELL1\cellular. Since I never used i, I have no clue what to do. How could I get st...
STM32WB09KE ble disconnect with 0x08 reason
hi ST support teamI am designing a circuit using the STM32WB09KE chip.However, when running the BLE_p2pServer example program from the package STM32Cube_FW_WB0_V1.1.0 and using the ST BLE Toolbox app (on iphone) to connect, I encounter a continuous d...
STM32WB standby mode WKUPx
I'm working with the p-nucleo-wb55, and I would like to configure the pin PA0 , PC13 to wake up the MCU from Standby Mode. I configued PA0 and PC13 from STM32CubeMX to GPIO_EXTI0 and GPIO_EXTI13 respectively.Config:PA0 : External Interrupt with Fall...
Resolved! Pin sharing problem with SWD and SPI3, GPIO
Hi. I'm developing a custom board using STM32WB09TEF7TR microcontroller.I had a problem re-accessing the microcontroller using SWD once I finished programming one time.I found that it is due to the SPI3 (PA3) and one GPIO pin (PA2) sharing the pin fo...
Resolved! Bluetooth LE Audio pairing between Laptop and Hearing Aid
I want to pair my Oticon hearing aid with a Bluetooth LE audio/Auracast transceiver for streaming from laptop or mobile or TV to my hearing aid. It is a personal use case and am looking at some of the chipsets along with Eval kit or USB dongle that S...
Resolved! CubeIDE includes wrong file for STM32WL33 when RTOS NEWLIB_REENTRANT defined
I am generating code for the STM32WL33 using CUBEIDE 1.17 and am using CMSIS V2. The IOC editor insists (but does not enforce) that NEWLIB_REENTRANT be enabled before generation. When compiling, the file "FreeRTOS.h" erroneously includes "newlib-free...
Resolved! STM32wb55 go to sleep in standby mode but do not wake up with sequencer
I am trying to use the standby mode. As the datasheet specifies, it can only wake up from this mode from the reset pin, wake-up pin, or RTC trigger. I searched on the internet to find out how to do it.If I use standby mode like this in the main it wo...
No more advertising after an interrupted pairing
Hi!I am using a STM32WB55 on a custom platform.I added "just work" encryption that will force a pairing with my device when I am using a protected characteristic thanks to ATTR_PERMISSION_ENCRY_READ/WRITE.My enc_key_size is 10, my CFG_IO_CAPABILITY i...
