Ask questions and find answers on connectivity ICs, focusing on protocols and I2C challenges on STM32 Nucleo boards and BlueNRG products.
I'm searching for detailed information on the Serial Peripheral Interface (SPI) protocol used by the ST33TPHF20SPI component, including register details and specific IDs that need to be read or configured.
Can Mode 2 of the L9663 read the sensor data directly with the MCU? Or do we go through SPI?
I am using the blue-nrg-lps,but when i test the hid example project , it cannot work in win11,but it is ok in phone and pad,so anyone can tell me why? A new player of ble-nrg-lps...
DK version:BlueNRG-LP DK 1.1.0chip:BlueNRG-345AC2 problems of the ble hid keyboard project. 1st, if BlueNRG-LP is not conneted to any device,it keeps going into RESET ,go on and go on.when it connected to one device,this situation stoped.2nd,BlueN...
Hi All,In the reference manual for the BlueNRG-LP Cortex M0+ microcontroller (RM0479), it states both page and mass erase functionality for the flash controller. But, only one "ERASE" command is given (0x11), which appears to be for page erase.Does a...
Hello All,I am new to Bluetooth and would like to use the BlueNRG M2 as a hosted network co-processor. I am reading the Bluetooth LE primer from the Bluetooth SIG. Could someone please point me in the direction of some resources that allow me to use ...
Hi.We are trying to measure analog values using BlueNRG-2.We want to calculate the accuracy, but we can't find any description of accuracy or drift for Vref (0.6V) or adc in the datasheet.Are there any reference materials or data available somewhere?...
Hi ST Community,I use the X-CUBE-BLE1 library and the SensorApp application, and I can understand most of the functions used, but when I want to add a value to my characteristic, I can't understand the address used and why.The address of the "environ...
Dear community, I'm using steval idb008v2. I'm trying to debug it with stlinkv2. Is it possible to do it or not? Do I have to move some pins or something similar? The application replies me that so stm32 board is not connected. Any suggestions please...
I'm developing a power line communication with the ST7580. Sometimes I get an error code 0x08 returned by ST7580_DlData function. This code is not listed in Table 14 of the user manual. What causes this error?
