STM32WB55 + Helix MP3 decoder: PCM plays 6× too slow via SAI + DMA
Hi all,I’m testing MP3 playback on a Nucleo-WB55RG.Setup:SD card via FATFSHelix MP3 decoder (libhelix-mp3)PCM out via SAI1_A (I²S) → external DACDMA in circular mode, 2× half-buffer callbacksWhat works:A test sine wave buffer played via SAI+DMA works...
Use FP-ATR-LORA1 on B-L072Z-LRWAN1 without Accelerometer
I am trying to read GNSS data using B-L072Z-LRWAN1 and GPS module. I installed FP-ATR-LORA1 and wrote the project to my B-L072Z-LRWAN1 and viewed it with Teraterm, the following error message appeared."Accelerometer NOT initialized"I don't use an acc...
Can BlueNRG-M2SP/M2SA support multiple Central/client connections simultaneously in Peripheral/server role?
Hello,I am working on a project with STM32 + BlueNRG-M2SP/M2SA and using a custom mobile app to connect over BLE.Here is my setup:The BlueNRG-M2SP/M2SA IC module is configured as a Peripheral (Server) with my stm32l0 mcu.The mobile app scans, finds...
STM32WB1MMC external antenna design support and calculation solution
I have previously worked on a BLE-based application that required an external antenna. Based on the use case, I selected the STM32WB1MMC module, which, according to its datasheet, supports external antenna connections. I designed the schematic accord...
STM32WB5MM not reaching deep sleep (STOP2/Standby) – still consuming 20 mA
Hello,I am working on STM32WB5MM custom hardware and trying to implement deep sleep mode using RTC wakeup interrupt. What I want to achieve:MCU should stay active for ~30 seconds after reset.Then enter deep sleep / STOP2 mode.Wake up automatically ev...
Not Receiving UART message from STM32WL5M to Laptop
Hi there, I have an B-WL5M-SUBG1 evaluation board which uses the STM32WL5M module.I am having problems with the STM32 receiving a message I am sending it from my laptop via python. I connect between the stm32 and the laptop via an RS422/485 converter...
Resolved! Update FUS to version 2.0.0 and BLE Stack via FOTA
Hi,We are using the STM32WB5 series. We have implemented a FOTA mechanism to update the BLE Stack and the FUS (both separately).We have noticed a new version of the FUS (2.0.0), which, to our understanding, is not backward compatible with older versi...
STM32WB09 Deepsleep mode with BLE
