Generic-Switch-App: After restarting the device, button 2 cannot trigger automation
Hi,When the device is first added to Apple HomePod, pressing button 2 can trigger automation, and it is always effective no matter how many times it is triggered. But once the device restarts, pressing button 2 again is almost always ineffective. Gue...
B-WL5M-SUBG1 LoRa HAL Setup and/or TX Failing
Hello,I'm using the B-WL5M-SUB1G, using Visual Studio as my programming environment, attempting to get LoRa TX working without using the middleware.The code is below. The project serial output is below the code block. Referencing RM0453 Rev 6 (STM32W...
Detect Zigbee Network Loss
Hi,I have the problem, that my MCU seems to loose its connection to the network quite often (after some minutes or hours usually) and is therefore not usuable.I would like to detect this in my Application and then trigger either a rejoin (if possible...
STM32WB55 Low Power Mode problem (stop mode and sleep mode)
Hello, I have an STM32WB55 processor. I use BLE. I use FreeRTOS.I call the functions HAL_PWREx_EnterSTOP1Mode or HAL_PWR_EnterSLEEPMode.Before that I call the HAL_SuspendTick function.But somehow I exit WFI. Somehow an interrupt comes but I couldn't ...
Resolved! UART not working with LoRaWAN
Hi, I'm using the LoRaWAN end node example from the stm32cubewl v1.3.0. The board im using is the RAK3172 based on the stm32wle5ccu6 chip. The application i want to build reads data from a modbus using UART and sends it through lorawan. I have assign...
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...
