BLE advertisement with irregular time intervals

Hi,We are testing BLE advertisement intervals in noisy environment(where there are multiple BLE devices around). The minimum and maximum BLE advertisement intervals we set are 20ms and 40ms. Usually when we place the device in shielded box all the ad...

Why can't STM32WB55 USB and BLE work at the same time, using firmware version 1.12.0.

I have to unplug Nucleo after flash to start BLE stack.

Whenever I upload code to my STM32 WB55 Nucleo to start Wireless stack (when I do not unplug and plug again there is no BLE device when I open ST BLE Toolbox) I have to manually reset device.Is there a way to skip that step? I mean, when I do debug i...

Is it possible to power an STM32WLE5 with variable voltage ?

Hello,I would like to power an STM32WLE5 with two voltage levels:VBAT: 2 series AA batteries, yielding a voltage comprised between (~3.2V and ~2V) over the life of the batteries.VBOOST: A boosted voltage from the batteries with a target of 3V. If the...

BLE HID ON STM32WB55 DOESN'T WORK NORMAL WHEN RECONNECT WITH WINDOWS 10

Hello everyone, I have a project using BLE (bluetooth low energy) of chip stm32wb55. I used example project provided by ST, this project is BLE_Hid in folder STM32Cube _FW_WB_ V1.16.0 of ST (pictures below). I loaded it to board P-Nucleo-WB55 then co...

Hello I set the variable  uint8_t test as  test = test + 1 in main.cand send this variable via BLE in p2p_server_app.c to PC with next command P2PS_STM_App_Update_Char(P2P_NOTIFY_CHAR_UUID, (uint8_t *) (&local));Also, set it in  main.h extern uint8_t...

Hi there, I'm trying to use LPUART on STM32WB55. I can not set BaudRate to 1200. In cubeMX I got this Baud Rate must be between 7.813 KBits/s and 10.667 MBits/s. How can I set Baud Rate to 1200 ? I need for SDI12 communication. Thanks

HI TEAM i tried to unlock read and write protection of stm32wle5jc controller with external j-link programmer. but now pre-flashed AT command Firmware is deleted. now AT commands are not working. can you please help to resolve this issue.

i am using stm32wle5jc controller. so i am using adc in polling method and interrupt method in while loop. but i can't measure both samples at a time. i am getting only one adc samples after comment another(interrupt) method only.
