Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
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...
Hi,I am trying to use S2-LP DK with a Nucleo + S2-LP Shield. I tried several combinations (4 computers (Windows 10), 6 Nucleo Boards (STML053 and STML152) and 4 S2-LP shields, S2-LP DK V1.2.0, 1.3.0, 1.3.2), I always get the error that I have the wro...
Android R can't get LSM6DSM HAL Accelerometer/Gyroscope data on iMX8MM board.following the steps as mentioned :1.copied the hal source code into hardware/STMicroelectronics/SensorHAL_IIO.2.Looking to the Documentation folder i have made the changes a...
After closing serial port, when i re-open serial port with the updated baud rate, I'm getting an error: Failed to execute MI command: -data-disassemble -s 4294967228 -e 4294967330 -- 3 Error message from debugger back end: ...
Hello Everyone,I am looking for RF Chipset which is certified to be used in Automotive products with ASIL-D certified and other certification if any. Please let me know, which are the series of RF chipsets which I can refer to .Thanks in advanceRgdsS...
Hello,I have created a pcb using RGB 8x8 leds. I'll refer to the RGB 8x8 LEDs as 'modules'. These modules are controlled via the LED2472GBTR. There are 10 modules, thus, ten LED2472GBTR's.This is all then controlled via a PIC18F87K22 MCU.At present, ...
