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...
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...
Hi I am using Bluenrg_m2 expansion board X_Nucleo_Bluenrg2 along with the controller Stm32l476rg. Reffered example is 'SampleApp' form X_cuble_BLE2_v1.0.0.I am trying to send 160 bytes of the fixed data over BLE frequently but after sending one packe...
Hey There, Firstoff : i just started using the STM32 boards and my not know everything to expect me to..Ive got two STM32L432KC boards and two SX1261 MB2 LoRa.Shields.I want to implement a direct communication between them without any Gatewayas / Lor...
I want to make a usb hid keyboard stm32. it possible in addition to the 6 keys that I transmit to add another byte in which to contain a variable that can be read by the application on the computer? Ex: | 0 - Key modifier | 1 | key1 | key2 | key3 | k...
Greetings,I am working on a project where I am updating hardware from the SPBTLE-RF module to the BlueNRG-M2SA module. I have upgraded the module and am now looking into what I have to update on the software. Effectively, I am upgrading from BLE 4.1 ...
Hi,Bought the STM32 Nucleo kit w. USI Lora shield.Disappointed when I found out that the documentation wasn't that great.When using AT_Master or the End_Node example I dont find any options for retrieving the debug data.... Is the only option I have ...
Dear Team,I use stusb4500 and desgin this circuit,I connected type C with this circuit and measured VBus got 20V, then a few seconds later stusb4500 broke down.Anything i have lost in this circuit then made it broke down? How to fix this circuit to ...
Hi everyone, I 'm on a project and sould developp a SPI communication between x-nucleo_idb05a1 and stm32F0 MCU and connect with a phone.The samples given on CubeMX are a bit complexes for what I have to do. I just want to send commands over SPI to in...
I'm using a BlueNRG-2 Evaluation Board in network coprocessor mode with the GUI. Firmware is DTM v3.1. When trying to set up a secure paired connection, I sometimes get an event ACI_GAP_PAIRING_COMPLETE_EVENT with a Status code of 0x03. Status codes ...
