STM32WB55 - Other perfipherals does not work when BLE thread is running
Hello, I am working on a lorawan-based project. I use STM32WB55. I know there are 2 cores in this MCU and ble is running on the second core. My code and other peripherals run smoothly when BLE thread is not running, But when the BLE thread is running...
After initialization, I2C is always busy
I am using the Nucelo board and communicating with an IKS02A1 trough I2C2 using PINs PA11 and PA12 with the following configuration: I have initializaed the I2C folowing the guidelines in "stm32wlxx_hal_i2c.c", and when I use "HAL_I2C_IsDeviceReady()...
Resolved! STM32WB55 Ram Memory Size
Hello guys, how are you?I'm investigating some .bss overflows i'm facing and i ended up on some weird question. Linker file for STM32WB generated by CubeMX is as follows:RAM1 (xrw) : ORIGIN = 0x20000008, LENGTH = 0x2FFF8RAM_SHARED (x...
Resolved! Bluetooth LE Isochronous Channel support for LE Audio support in STM32WB?
Hi, do the STM32WB support Bluetooth 5.2 LE isochronous channels?Thanks!
Resolved! USB Composite Device, Mass Storage - HID. Is it possible using HAL?
Hello guys,I've been researching over the internet and in this forum about creating a composite device on STM32WB5M. I need to create a device that has a HID and a mass storage over the same USB. I saw some old posts saying it was not possible but at...
Resolved! If I supply power only for SMPS, the microcontroller looks not booting. is it correct?
I'm designing a power line for the STM32WB55 microcontroller.I'm checking the power system on the Nucleo-68 board but I found that the microcontroller cannot send a Bluetooth signal if I connect Vsmps only when booting the microcontroller.I also foun...
LoRa-E5 STM32 WLE 5JC: i2c doesnt work if not in debug mode [ioc -> debug -> serial/disabled]
My I2C doesn;t seem to work whenever i turn off debug pins in IOC. I used a diff to see the changes but it seems fine to my untrained eyes:$ git diff diff --git a/Core/Inc/sys_conf.h b/Core/Inc/sys_conf.h index 988f1e8..b3cb386 100644 --- a/Core/Inc/...
Resolved! Software trigger for LPTIM1 (Low Power Timer)
Hello,I am trying to use the LPTIM1 as a timeout counter of 5s. Each timeout the device would read a measured value from a sensor and send it by uplink.I want to trigger the LPTIM1 by software, but I do not know how to do this. This is probably a new...
