Interfacing BlueNRG2 with Raspberry PI 4B

While interfacing BlueNRG2 ( i am using jumper wires from STEVAL-IDB008V2) with raspberry PI 4.which other lines do I have to use apart from MISO,MOSI ,SCK and Ground.I am using only CS line and making it low and then high at the end of communication...

How can I emulate the iBeacon scanner with a second BlueNRG-LP board?

What I want to do is quite simple in theory :1) Load the BLE Beacon application from the BlueNRG-LP Development Kit (DK) on the first BlueNRG-LP board and run2) Verify with an Android BLE Scanner Phone app that the BLE Beacon app on the BlueNRG-LP is...

I would like to know the meaning of ADVdata in the (aci_gap_update_adv_data) function

Hello all.I am currently testing the STEVAL-IDB008V1M development version, I am using the BlueNRG-2 example code (BLE_SensorDemo_BlueMSapp) and there is manuf_data[26] in the function (Set_DeviceConnectable) in the sensor.c file. Can anyone explain w...

Increasing size of Attribute array on BLUENRG-M0 > 700 bytes

Hi,I am using the BLUENRG-M0 (Nucleo board) and a STM32F446 Nucleo 144 to build a BLE peripheral. I am creating my services with the BLUENRG GUI v4.3.0.My FW versions on the BLUENRG areBlueNRG HW version 3.1BlueNRG FW version 7.3Motherboard FW 1.9My ...

I made an acquisition board with STM32WB55rgv6. I want to save ads1299 sampling data to SD card by FATFS(via spi). But my write speed is only 1KB. Here are the measures I have tried： ①Improve SPI clock ②Replace faster SD card ③Mybuffer is 51200B

Although every time I write in a single block instead of multiple blocks， and I only use SPI, not DMA. But the write speed is too low, only 1KB. I've browsed through many measures, but they still haven't saved me. I used stm32cubeide to develop this ...

74HC138, One I2C bus - 4 I2C devices

Hi,I am using 4 NFC 4 Clicks in combination with 74HC138 to connect them directly to on I2C bus. Can anyone hep me how do I implement this in my code so that he controller would switch between every I2C device.Rgrd,Anej

There is no cdc-acm driver on the existing embedded Linux computer side (Driver installation not possible) The stm cdc device is detected, but it couldn't be connected to TTY port. Can I connect with libusb? If not, is there a way to connect?

Getting DAC output via I2S line

Hello, I want to send data to the DAC with the I2S protocol (assume we are sending an array) and see a sine wave at the output.At this point, I would like to ask: Does the DAC in the stm32f407vg model mean the CS43L22 IC or an internal DAC unit in it...
