Resolved! USB FS Data Traffic Suspend And Resume

Hi,I configured USB FS on my STM32WB55 NUCLEO Board and it works as I expected (configured as CDC). I can send and receive data to/from Host (my PC) but now I have the need to suspend temporarly Data Flow and then reprise it.My goal is to collect som...

Low power ADC continuous conversion with RF subsystem enabled.

We are looking to use the STM32WB5MMG to measure a few seconds of data, then transmit that over bluetooth.We have managed to get the current consumption of the internal ADC during this measurement down to around 500 uA using low power sleep mode, how...

LoRaWAN Middleware to SubGHz_Phy middleware connectivity

!!Naive question!!I have started LoRa development recently, I am using RAK3172 module which has STM32WLE5CCU6 embedded with it. Now during the development, I am seeing that the module is transmitting and joining the server but it is not getting any j...

Resolved! I'm curious about the power part of the STM32WLE

I tried to design a board using the STM32WLE5CCU6, so I referred to the reference designs MB1720,1842,1848, etc.However, I confirmed that the VDDRF part, which is the part specified in the data sheet, is open with the SB connector.I searched for the ...

Enable and use VREFBUF for ADC measures

Hi, I am following the instructions in STM32 reference manual to configure VREFBUF to use in my ADC measures. In chapter 17, it explains that it is needed to set ENVR to enable VREFBUF, then reset HIZ and set VRS (in my case for VREFBUF = 2.5V), then...

Porting BLE_OTA_ServiceManager on a host processor and use the BlueNRG-LP as coprocessor

Hello everyone,I'm using a STM32L4 in a application and the BlueNRG-LP as a BLE module in network coprocessor mode with DTM SPI. I'd like to update my main firmware through BLE OTA, a kind of Bootloader OTA. So in my main MCU, there will be this Boot...

Failed to read time and date in STMWLE5 software

I want to record the time of sensor activity in a program running in STM32WL MCU but only get the value of 0. The program is modified from the example LoRaWAN_End_Node. Below please find the RTC setting and the code to get the date and time. Can any ...

wrong transmission through BLE data writing in STM32WB55

I programmed a microcontroller to return received text data from BLE using UART.However, I can get only 4 alphabet clearly and the next alphabet becomes broken.For example, If I send the text "aaaaaa", then the microcontroller return "aaaa0(9)??" or...

STBox RTC time recording problem

Hello everyone,I encountered an issue while trying to record sensor data to an SD card using the sensorTile box. The sampling frequency is set to 50 Hz. However, upon checking the CSV file, I noticed that it only displays one decimal place after the ...

Problem FUS when I try to load BLE Stack on STM32WB15xx

Hi everyone.I have a problem when I try to load BLE Stack on STM32WB15. I can connected the MCU to STM32Programmer and there can recognize the cortex. At the moment to load the Stack, STM32Programmer send me the configuration about FUS and I cand rea...
