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 ...
Hi,I am using STM32L072 LoRa discovery kit and enabled UART with DMA. Some times my code gets stuck in HAL_UART_Receive_DMA( ....) function at the line SET_BIT(huart->Instance->CR3, USART_CR3_EIE);This is called at the begining of the code. It wont r...
Hello,I measured the performance of uSD card connected through the SPI on Read/Write operation.The weird thing is that the Block read speed is 3x to 4x slower than the write speed. I'm writing/read 4kB of data and the SD card is formatted with 4kB a...
Hi, I am using the NUCLEO-WL55JC1 to send/recv the data via LoRaWAN.The sample code AT_Slave in SDK 1.3.0 worked well when I tested at region AS923. However, I started to test at the region EU868, the device worked until I reset the device.The device...
I am using STM32WB5MMGH6 as slave and communicating with host using BLE. I would like to ask a question here: He has read AN5270 and is considering a method for the user to detect when data transmission fails due to BLE disconnection etc. during data...
Throughout the codebase the PLACE_IN_SECTION macro is used to place bluetooth related static variables into their own sections. I guess this is done increase the isolation from possible errors in other parts of the code.The sections (for example "BLE...
Hi,I plan to design and build a soil moisture sensor for our plants at home, based on the STM32WB55 (I need ZigBee / Thread). But I want to build up a prototype by using my STM32WB15 nucleo board and some of these cheap Arduino Soul Moisture PCBs wit...
I'm looking to create a test case to verify that the handling of the interrupt generated by RTC SSRU is working correctly.In the LoRaWAN code base, the SSR time is set up such that the underflow will happen after about 48.5 days.There doesn't seem to...
So I just don't get something in BLE,My service discovery says it is from 0x000C up to 0x0011. my service has 2 characteristics.but then I scan the characteristics in that range (from 000C to 0011 ) and get them but also get an gatt error on attribut...
Hello Dear,Was debugging this command today, and unfortunately found it to be working only partly.From what I see, is that the command aci_gatt_disc_char_by_uuid_cp0 occasionally works and occasionally doesn't.Currently developing on the stm32wb55, ...
Hi there! We are developing a new STM32WL based product that must be compatible with the existing STM32L0 + S2-LP products. It appears that the GFSK data whitening algorithm is different(?). I used an SDR dongle to sniff the raw bytes transmitted...
