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.
I am working on Ethernet (Part No : STM32F779BI )I am able to display webpage using ethernet with follwing pin mapping PE2 ------> ETH_TXD3 PG14 ------> ETH_TXD1 PG13 ------> ETH_TXD0 PG11 ------> ETH_TX_EN PH3 ------> ETH_COL PH2 ...
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...
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...
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...
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...
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...
