Ask questions and discuss STM32 wireless solutions and their implementation for running Bluetooth LE, Zigbee, LoRaWAN applications.
Dear all, The X-CUBE-MATTER Expansion Package is now available on our official website following this link MATTER - Matter software expansion for STM32Cube - STMicroelectronics It is a reference implementation for the demonstration of Matter on ST...
Please go and visit our wiki pages where you can find a lot of information on our wireless product families (WB, WBA, WL) and the supported protocols: BLE, Zigbee, Thread, Matter, Lora, ... To begin your technical journey, please start from this top ...
HiI just bought a B-L4S5I-IOT01A Discovery kit.Confession: I am completely new to ST, and I reckon I have a mountain of learning to do in a short time.However, I just read the blurb on the back of the kit and it essentially says: 1. Verify the jumper...
The errata sheet ES0500 - Rev 4 mentions a workaround for 2.8.3 DMA stream locked when transferring data to/from USART where bit 20 of register DMA_SxCR shall be set. This register is not mentioned in the reference manual and not in the respective he...
Hi, I've got an STM32WB15CCU6 on a custom board and am currently trying to get it to boot from Flash memory after programming it with the STM Cube IDE.Debugging a program in the IDE works perfectly fine, but if I flash it to my microcontroller (using...
Hello I have two STM32WL55JC2 boards and I would like to run the PingPong DualCore example available in this WL package folder : I run the .project file on the STM32 IDE and I get this: After adding several missing .h files I manage to flash to the b...
I want to send 2 kbyte data using BLE in WB55.Becasue the packet size is limited to 245 byte (it may be 509 byte if change ATT-MTU to 512 but still I couldn't make it.)So, I wonder whether there is good example for this.Could you suggest anything?
How can I check the ATT-MTU of the current connection (not setup)?What coding can I use to check? For example, I want to return ATT-MTU size through USART after measuring it in the microcontroller.
During several trial to use ACI_GATT_Write_Long_Char_Value,I found that the microcontroller dosen't start its BLE advertisement anymore.It only can indicate wireless firmware version.I think that some transmission cause an error.So, I tried to rewri...
HI everyone, I'm working on creating a sequence of files, that everytime the program starts to run, it creates a sequential file of the last one created. But I'm having troubles trying to create a logic that compares the name of the last file and cre...
Hi.I can see that CFGBSY bit is set and reset in some MX peripheral init functions, but the main problem is that it stays set after MX_TIM1_Init and it locks my flash for any operation.Did anybody saw this kind of problem?Any help will be appreciate...
