Does STM still have demo software available for STOTG04ES as per User Manual UM0212

Need software driver for STOTG04ES

BLUENRG how to enable notification?

i am able to read characteristic by using ACI_GATT_READ_CHARACTERISTIC_VAL, and update characteristic by using aci_gatt_update_char_value_ext(), the returned value is correct. howevever, the client's aci_gatt_notification_event() was not triggered.

Hello When is the next revision of the S2-LP is coming out ? Will you fix the problem with the MISO line on this revision ?

What kind of interfaces (open drain, push-pull, pull-up, all of them?) are compatible with the input/output of the ST2378E?

Hello ST team,I need to create a TTL interface between two microcontrollers. One of them is supplied with 3V and the other one with 5V.The 3V microcontroller output can be configured with a pull-up or in open-drain.The 5V microcontroller has a 5V pus...

X-NUCLEO-IDW0M1 examples doesn't work for Nucleo-F401RE (HAL_UARTx_Receive_IT Error)

Hello,I'm trying to run the examples for X-NUCLEO-IDW0M1 WiFi expansion board and they doesn't work. I'm using a nucleo F401RE which is supposed to be compatible with this expansion board. I just plug both boards and run the examples. Once the progra...

stm32f103ZCT6 communication with an ADC IC (ad7730) through SPI works fine in the debug mode but when I disconnect it from stlink and run the board normally, I receive random and wrong data.

 After inspection I realized that RCC_CFGR register is different when running in different modes (debug and normal). I fixed the issue by writing RCC -> CFGR = 0x1F040A. Now the register is the same but the problem still exists.another strange fact i...

VL53L1CXV0FY/1 proximity sensor application note

We are building solution to identify post box filling level with VL53l1x proximity sensor. Letters in the post box may be aligned in a Zig jag manner .As per our knowledge laser beam (time of light) can identify distance between the sensor and plane...

MODBUS RTU reading problems

I have a problem with modbus-rtu communication in my stm project.The STM32F446RE is connected to a MAX485 board by UART1 to RO-DI pin and by a GPIO pin to RE-DE.A typical instruction (variable:INSTRUCTION.array_instruction) is something like 01 06 26...

S2-LPQTR with external power 1.8V on SMPS2.

Hi all! I developed custom board with S2-LPQTR and STM32 uc. S2-LPQTR - answer through SPI and transmite to radio channel through BALF-SPI2-02D3, but don't receive any message.I connect on SMPS2 pin external 1.8V from LDO. In all example boards inte...
