ZigBee timeout to join the network

Hi,The ZigBee Coordinator does not allow the new nodes to join the network after a certain amount of time. I want to change this behavior. I want the coordinator allow the new nodes to join the network at any moment of work. How to change it?Best Re...

Is periodic advertising sync supported by the coprocessor?

I'm trying to enable periodic sync so that another BLE device can sync with the stm32wb5mmg and receive advertising data from it. Through bluetooth sniffer I can see that the 'Sync Info' flag in the Extended Header Flags is set to zero, meaning no sy...

STM32 LOCKUP causes in the field?

We're using the STM32WB55CE across a range of products, using a mostly shared codebase. Thousands of devices deployed and mostly very stable, but one particular device (the one with the largest code base) is causing a lot of grief..After a few weeks ...

HCI_LE_TEST_END long response (BLE_TransparentMode - STM32WB55)

Hi, I'm trying to run BLE_TransparentMode on my STM32WB55VG for DTM purposes. I'm using FUS 1.2.0, Wireless Stack 1.13.2 (stm32wb5x_BLE_HCILayer_extended_fw), BLE_TransparentMode app 1.13.2.I'm building it in STM32CubeIde 1.8.0 with CubeMX 6.4.0, onl...

CubeIDE keeps generating error????

Hello.I have an STM32WB55 pcb that I developed. I have been working with it for over a month now and all was working fine. Today the CubeIDE decided to generate an error (see below):Download verified successfullyFailed to assign value 80037b1, to r...

Code Get Stuck

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...

Slow block read with SPI fatfs

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...

STM32WL LoRaWAN send data error after restore the context data from NVM

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...

Detection of data transmission failure due to BLE disconnection during data transmission

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...
