Why is SPI not working without a floating wire on the MOSI line in SPI?

I've connected the cno410 LED Driver to NUCLEO-F446RE which works with SPI lines, whenever I've linked to it directly, it works as expected. we have designed another PCB shield on the Nucleo board. On top of we have connected this LED Driver now. Now...

What is the function of hci_notify_asynch_evt since it has no user code / can't find in documentation

I'm trying to use X-NUCLEO-IDB05A2 on an Nucleo64 STM32L476 board. I want is to initialize the IDB05A2 and pair it with smartphone(s) to detect if any of these paired phone(s) is in range or not (so the phone(s) should acts as paired beacon(s) / ther...

Is there a way to use WIFI module and Bluetooth module simultaneously?

Greetings,For a project of mine, I would like to use on B-L4S5I-IOT01A IoT discovery kit both Wi-Fi ® (Inventek Systems ISM43362-M3G-L44) module and Bluetooth® Low Energy (BlueNRG-M0) module, in simultaneous.Reading the user manual for the board (UM2...

Hello every one, I'm using BlueNRG-m2 to communicate over ble, I make an interface with blueNRG over spi from stm32f446 mcu, my problem is that the ble linked list used in ble stack seems like it doesn't initialized correctly.

when I try to read software version (before gap or gatt initalization) using aci_hal_get_firmware_details(), it ends up to this and always fail to get the data correctly

SPI slave not reading the data in first run

Hi all, i got to know a bug/problem/issue in SPI communication. one of my colleague is working on designing controller(complete SDK), he has an issue, the issue is, whenever he writes the data from master it writes properly, but when trying to read t...

Problem with X-NUCLEO-S2868-a2. Cannot receive a completed frame from WMBus gateway.

We have a L152RE module connected to a RF transceiver called X-NUCLEO-S2868a2. So, our mission is to measure some frames received from a water gateway by WMBus. We have implemented the firmware SUB1GHZ (written by ST). We receive the first block of t...

How to emulate BlueNRG-2n with BlueNRG-2

Hi,We have a custom board with BlueNRG-2 and wants it to act as a co-processor so it can be controlled through SPI from another MCU (STM32L4R9).The BlueNRG-2 has been flashed with STSW-BNRG2N-V320 firmware through the bootloader interface.DIO0 SCKDIO...

What is the maximum SPI speed and MCU system clock which can be configured for using BlueNRG2-M2SP module with it

Hello, in the X-CUBE-BLE package this document STMicroelectronics.X-CUBE-BLE2_GettingStarted.pdf says the maximum SPI frequency could be 1Mbits/s . In high perf MCU running at SysClock >500 Mhz , is it possibe to interface BlueNRG2 with it?using Cl...

BueNRG2-M2SA in Application co-processor mode with another master

Hello, I am interfacing BlueNRG-M2SA with a Linux host and don't want to use it in network co-processor mode.is it ok if I use it in application co-processor mode where m2sa module does all the work and sends the data over to another master or anothe...

Is there an adjustment in track width or length necessary if i change the layerstack for the BALF-SPI2-01D3.

Recommendet is 66µm CU with 305µm distance to ground layer. I would like to have 35µm CU with 180µC distance to ground layer.
