Resolved! When I get connected and paired to peer HAL RNG doesn' work
Having issues generating random numbers while being connected via BLE.In general use, HAL RNG works fine, and I get a random number without timeouts.BUT,Upon finishing the connection flow,connection mtu exchange pairing ,I start to get timeouts when ...
Resolved! Failing to initialize BLE on a custom STM32WB55CGU6 board
Hello,I’m trying to create a simple program to test BLE functionality of my board. The board does not have HSE but it has LSE. I'm not sure if that is a problem. I'm using PlatformIO for the programming, configurations and building/flashing. When I u...
Flash SR errors on startup
Hi all.I'm working on stm32WB MCU, I have a bootloader and an application. The bootloader only check if any update needed and jump to app. When app stops at main I can see that flash status register is set with PGAERR, SIZERR and PGSERR and I have no...
STM32 WB09KE - Emulate EEPROM from flash
Hello everyone, I am currently working with the STM32WB09KE microcontroller and need to implement EEPROM emulation, as this device does not have built-in EEPROM. However, I couldn't find specific documentation or resources related to EEPROM emulation...
Resolved! Establishing Connection - BLE P2P Server/Client B-WB1M-WPAN1
Hi, I am setting up a p2p Client and p2p Server example using 2x B-WB1M-WPAN1 boards. There is no example I can find for the B-WB1M-WPAN1 so I have taken the Nucleo example and modified to suit the B-WB1M-WPAN1. I cannot connect the p2p Server to the...
Resolved! Lora Relay Node
Hi,Anybody from ST or Users done any development or research on the "new" relay node on the STM32WL.Will the stack be updated or will we have to do this on our own?RegardsStefan
Resolved! After BLE OTA update, CPU2 stucks
Hi, I'm working on an OTA BLE bootloader for the STM32WB5MM module.I created from scratch with STM32CubeMX the same code as the OTA example for NUCLEO-WB55.I'm on BLE stack 1.21So far so good, I can update with the smartphone app.The problem I'm havi...
STM32WB15 FUS refusing to start
I was updating application firmware on an STM32WB15CC, but my user application wasn't advertising correctly. I decided to re-install the wireless firmware. However, I am unable to do so, as my FUS refuses to start. Reading the FUS infos shows a FU...
STM32WL54 does not wake up after 4-5 days in STOP2 mode
The device is designed i a way that, it should wake up every 30 seconds via RTC wake up timer or upon button press, read sensor values (for temperature and humidity ), if there is any change in these values , send packets via radio (SUBGhz) and ente...
245 bytes can be sent using BLE, but 512 bytes must be extended into a single packet.
