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...

Partial framebuffer article and generated code missing details

I am trying to implement this using an ILI9341 display, like here helentronica.com/2021/01/22/touchgfx-on-a-custom-made-low-cost-board-with-the-ili9341-controller-over-spi/The article at support.touchgfx.com/4.21/docs/development/scenarios/lowering-m...

Does your ULQ2803A have the standard eg; ULxxxx, IECxxxx ?

Hi ST expert,Our customer asked that your ULQ2803A have the standard ULxxxx , IECxxxx.But I could not catch it on your datasheet, also homepage and PRiSMA.Maybe your answer is NOTHING, so can you confirm it ?Thnaks, Yasuda / AVNET Japan

Inquiry about the production of other packages for product STULPI01A or STULPI01B.

Hello?​As title, I ask if a replacement package for the ULPI interface IC is planned to be manufactured.​Currently, the ULPI IC produced by ST is only a BGA package, but this BGA is too small in size and requires special specifications in PCB manufac...

Do ST offer any chips that would be able to support BLE 5.3/5.2 and use LE audio? My project has to have LE audio and i think BBLE 5.2 offers that. thank you

BlueNRG-2 sleep issues while working with the full "BLE_SensorDemo" Example Project

I am currently trying to understand why my "BlueNRG_Sleep" function doesn't work, from the main function where custom code should be, either while debugging or while using the battery with my BCN002 tile board. I use LEDs on before and after the slee...

BlueNRG-2 timestamp registration

Hello,I would like to ask for an advice related to the timestamp registration:uint32_t timestamp_A = HAL_VTimerGetCurrentTime_sysT32();and after some time we check the elapsed time using:int32_t diff_ms = HAL_VTimerDiff_ms_sysT32(HAL_VTimerGetCurrent...

We are developing a circuit with the STuW81300. Our doubt is: to write a register, do you have to send 32 bits directly? or can you send 4 bytes, one by one? Thank you.
