JSON Payload Not Received in Downlink in LoRaWAN
Hi everyone,I am using the LoRaWAN_AT_Slave example code on an STM32WL-based device, and I am operating in OTAA mode with the ChirpStack server to monitor the data. I am successfully sending sensor data to the server at the specified intervals.I have...
Inquiry About STM32WLE5C8U6 for 915 MHz LoRaWAN End Node Development
Hello, I am planning to develop a 915 MHz LoRaWAN end node using the STM32WLE5C8U6. My goal is to send data from several sensors—such as GNSS, temperature, and accelerometer—directly to a gateway without employing an external MCU. 1- Could you please...
Resolved! What do I have to change if I want to use LSI instead of LSE with the BLE_p2pServer_ota example?
Hello,I would like to use the BLE_p2pServer_ota example with the STM32WBA55CG as a template for a project. Since I do not have an LSE available here, I would like to use the LSI. Which settings (defines) do I have to change?If I use the LSI with 32,0...
SPI setting speed is too low.
Hi, I'm testing a custom STM32WB09TEF7TR board. To communicate with the analog front end, I need to use SPI.However, SPI communication requires 17 us setting time, which means around 60 kHz.This speed is very slow.So, the Initiation of SPI becomes th...
USB CDC device not being recognised by windows. (STM32WB5M, Bluetooth low energy)
Context:I have succesfully implemented a CDC device in a stm32f205 board 6 months ago.Now im trying to implement the exact same thing in my STM32WB5M discovery board.BLE is already activated and working P2P custom serverUsing CUBEMX 6.3.0FW package S...
How to develop Matter software expansion for STM32Cube v1.1.1 on macOS
Matter software expansion for STM32Cube v1.1.1. When I build 2_Images_SECoreBin on macOS development environment, the build fails probably due to postbuild.sh and prebuild.sh.Please let me know how to fix this.
STM32WLE5 Shutdown consumes too much current
we are working on STM32WLE5 development.We succeeded to enter Shutdown mode and measured supply current of less then 40nA when operated at 3.0V,but at that time, the VDDRF and VDDPA were not connected (0 volts), meaning we could not test the LoraWan ...
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 ...
