Reading Zigbee window attributes does not work
I'm trying to get a window cover to work, but can't seem to get the communication between attributes to work. I've been able to do this with the on/off cluster but this just doesn't seem to work. Also the examples on github are programmed very differ...
I2C on STM32WB09
I want to add I2C support to a BLE sample project, in particular BLE_Beacon or BLE_Peripheral_Lite.In CubeMX on non-BLE projects I can select PB6-PB7 for SCL-SDA respectively.In a BLE project there is a clash with TIMER and the I2C code is not genera...
Timer interrupt timeout issue with LoRa Wio E5 Mini(STM32WLE5JC6)
I have been using Seeed-LoRa-E5 github repository for my project. I have added code to send I2C sensor data to the LNS and the device joins and sends data successfully and the code works fine as expected. Now I want to add a timer interrupt and so I ...
Resolved! LoRa FHSS Receiving in STM32WL55JC (E5) module?
I want to work with Lora FHSS. Resources on this subject are limited. \STM32Cube_FW_WL_V1.3.0\Projects\NUCLEO-WL55JC\Applications\SubGHz_Phy\SubGHz_Phy_LrFhss. ;I looked at the FHSS example you told me about. This example works in TX mode only. It on...

Hi there! I'm just starting with the B-WL5M-SUBG1 and would like the source code for the program that runs on a newly purchased development board. The documentation says this code is available https://www.st.com/resource/en/data_brief/b-wl5m-subg1.pd...
Resolved! Programattically Enable/Disable Characteristic Notification
I have two custom STM32WB55 boards that I initially started with the P2P_Client/Server projects. I have the two devices communicating with each other. Once the communication is established, the notification characteristic is enabled from the P2P_Cl...
Resolved! LoRa FHSS support for STM32WL55JC (E5) module?
We purchased the STM32WL55JC Long Range Module board for a project. This board includes the LoRa E5 HF module. We are considering using LoRa FHSS in our project. Can this motherboard support LoRa FHSS? Does it support? I couldn't find much informatio...
Resolved! Doubts regarding timers
What are the differences between LPTIM and TIM, also doesTIM1,TIM2,TIM16,TIM17 work when the device is in STOP2 mode?
ADC: DMA ADC value is not updating after first reading.
I have configured the ADC in DMA mode to read a single pin for measuring external voltages.However, I’m encountering an issue where the ADC value is measured correctly on the first call, but on subsequent calls to the function, the ADC value does not...
Can not init BLE stack on CPU2
Hi, I want to develop a BLE application on the STM32WB55, but I'm having trouble initializing the BLE stack on CPU2. I call the functions to initialize it (like in the Heart Rate Monitor example), and then I receive an RX_IRQ from the IPCC where inco...
