Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I can't get my L9663 SPI working. My understanding is that any 32-bit data I send to MOSI will return a 32-bit data from MISO. However, I am not getting any response; MISO remains low the entire time. I am now using a QFP32 general adapter boar...
Hi, I'm interested to learn if the BlueNRG-LP chip 355AC can be set in dual mode (which is possible from example code), but over 2 different PHYs. I want the chip to be a central device over coded PHY to connect with sensors and over 1M PHY to talk...
Hi, I am trying to use the BLE (SPBTLE-1S chip) on my STWIN to send acceleration data, and receive some parameters. My first idea was to use a template from X-Cube-BLE1 with the following configuration : HCI_TL : BasicHCI_TL_Interface : UserBoardAppl...
Hi all,i have an STEVAL-MKBOXPRO that i want to reprogram.I found STSW-MKBOX-BLEDK here https://www.st.com/en/embedded-software/stsw-mkbox-bledk.html#documentation and specially example BLE_Sensor_DemoI follow "UM3227 STSW-MKBOX-BLEDK software packag...
I'm trying to build example GPIO_IOWakeup with Keil IDE based on BlueNRG-1. I got this screen.What are the necessary steps to activate building and set up necessary parameters?I try with this activity:What to do?
Hi I have connected Bluenrg LPS eval board (network coprocessor mode) with STM32L476 Nucleo board and both are connected via jumper wires.I'm transferring 30 bytes in a single packet from STM32 nucelo to Bluenrg LPS module what I have seen is, once s...
Hello Everyone,I am working on a product and recently due to chip shortage I have to change the IMU. I have selected LSM6DS. My MCU is Esp32. now when I send a query of I2C address it responds with 0x7E address while it should be 0x6A. I was using Ad...
Hello everyone I am looking into the STPM33/34. I only want to use 1 SPI bus for both ICs and select it with the SCS. In the datasheet I cannot see whether the MISO goes into tristate when the IC in question is not active. I also cannot see any infor...
Hi,during maximum heating tests of our device, we measured a case temperature of +92 °C on the STKNX (on top of the plastic package via thermocouple). The environmental temperature near the STKNX and the PCB was +85 °C.On the borderline, but ok in my...
Hey, So i'm using the STM32l4A6ZG and and I want to implement the ATWINC1500 xpro driver so i can use the APIs to successfully connect the ATWINC1500xpro module to the STM32 Host MCU.Can I use this driver : https://github.com/gd91/stm32_winc1500_stat...
