STM32WB: Maximum flash sizes for BLE stacks?

Hi,I am working with a STM32WB55RG and by checking the different BLE Stack_full versions available, I realized that their start addresses could vary quite a lot.Is there a guideline for the maximum size that any future BLE stack could have? Example:R...

Need the Reset Reason.

Hi Team,We are using the STM32WB55 Series for our product. At each power cycle or reset, we need to know what the reason is (like WD Reset, Soft Reset, or Pin Reset, POR reset).Could you please tell me by reading the which register, we came to know t...

Normal power consumption of STM32WB55 series in stop2 mode and how to make sure Core2 is not messing it up

Hello everyone,We're trying to achieve a low power consumption on a custom board which have a MCU from the STM32WB55 range. I think that I was able to get into stop2 mode as PC was way lower than in sleep mode, and the device could not be detected an...

Hello,I am having difficulties trying to sample both channels of the LTC1865 ADC and was hoping someone could point out my mistakes. This is my function to sample the channels. I am using the STM32WB55 micro.unsigned int READ_External_ADC(int chann...

Hi, We need to develop one LORA module based on a single STM32WL55CC module which can support 4 bands (433Mhz, 470MHz, 868MHz and 915MHz) with single antenna . Here attached once block diagram for your reference . Please do review.

Simple Ble Communication with stm32wb??

I've been starting a bl project recently.I want to implement simple communication using stm32wb chip. Like you can buy and use a UART-based Bluetooth module like HC-05.However, when I looked at the materials released on the web, there were many examp...

Hard Fault inside a RTC_Alarm_IRQ_Handler

Hello,I'm dealing with a problem in a STM32WB55, but the doubt is general about STM32 and FreeRTOS. Among the different tasks initialised in my program, I have a task running that puts the MCU in STOP2 mode. In parallel there is an RTC Alarm programm...
