Hello,I am an engineering student currently working with the BlueNRG-M0 for a student project. My setup consists of a mobile application communicating with embedded firmware through the BlueNRG-M0. However, I'm facing an issue: the throughput is qui...
Hi,I am using Stm32f0 as the modbus rtu MASTER, I have done setting up UART1 Rx and Tx for communication, I am sending the Master query to the Slave device (Simply Modbus Slave application) link https://www.simplymodbus.ca/download.htm. If I connect ...
I am working through a workshop tutorial on how to configure and use GPDMA transfers via the linked list functionality provided in STM32CUBEMX. When setting the linked list runtime configuration a Source Address, Destination Address and Data size are...
Hi,The ST4485EB IC mentions that it needs a 3v3 supply. How can we ensure that the A and B lines interoperate with other RS485 devices working at a 5V logic level as the datasheet mentions . Should I just provide 5V supply to this chip so that it int...
i have buy VNH5180A-E powersso-36 tp pakage some 20pcs but i check measurement not as per datasheetcan you let me knowdimension A /a2 = 2.53 mm as per our ( as per datasheet is 2.15-2.47mm)dimension H = 9.91 mm as per our ( as per datasheet is 10.1...
Where can I find documentation on the BLE attribute handle offsets? I was adapting code from the sensor demo for the BLE NRG 2 and am trying to understand the "aci_gatt_attribute_modified_event" callback. Through observation and experimentation I fou...
Hello everyone,I am currently working on a project where we are trying to send random data from an STM32 Nucleo-F429ZI to a Raspberry Pi 4 over the I2C interface. We have encountered an issue where the I2C address is not detected on the Raspberry Pi ...
I am wondering what the logic voltage is for the I/O pins on the STUSB4500L. Under operating conditions they are listed as 0V to 4.5V, but the example circuit shows I2C pullup resistors to 3.3V. Is it safe to connect these I/O pins directly to a 3.3V...
Hi All,I am using BlueNRG in my product for BLE communication. Able to detect peripheral devices in our central- Mobile Application and works fine but issue with Multiple peripheral device access where need to connect every time with specific periphe...
Hi! We have designed our own custom board based on the X-NUCLEO-BNRG2A1, we bought the BLENRG-M2SP module some months ago. We discovered based on this, that these are coming empty (not flashed). We have flashed them using all the available images pos...
