Interface and connectivity ICs

Hi I am implementing a nrf24l01 driver with the use of stm32F4 the SPI transmit and receive works with the polling method yet not with DMA method.I already configured the DMA on cube mx and IAR WORKBENCH this is the code part i put the dma as cmnt

//3. Read single byte from a registeruint8_t NRF24_read_register(uint8_t reg){   uint8_t spiBuf[3];   uint8_t retData;   //Put CSN low   NRF24_csn(0);   //Transmit register address   spiBuf[0] = reg&0x1F;   HAL_SPI_Transmit(&nrf24_hspi, spiBuf, 1, 10...

Unable to load the firmware

Hi, first of all i'm a noob with bluenrg products,I'm using the STEVAL-IDB008V2 and i'm able to load firmware using the RF-flasher utillity via COM port identified as ST DK just fine, but when i try to load the same firmware using a standard com por...

Hi, in sw package BlueNRG-2 “over-the-air�? (OTA) firmware upgrade what happened in case : 1 - power failure during upgrade? 2 - lost of BLE during update? in configuration OTA service manager framework

I have customised board for one of my project. STM32GO32J6M3 8-pin MCU is used. when i connect st-link i am getting error called st-link " no target connected" how to solve this?

RS485 3.3V or 5V IC For Larger Distance

Hello, Our application needs longer distance RS485 communication, So, From 3.3V and 5V RS485 IC (available in ST), which to choose for larger distance coverage?Thank You

What is different between ST3232 and ST202?

I knew that ST202 is compatible for ST3232. So I changed only ST202 into ST3232 without any circuit changing.But ST3232 doesn't work.​What is different between ST3232 and ST202, other than power supply voltage?​I found the difference in typical appli...

Facing issue in the DeviceConfiguration() function while initialization of BlueNRG2 chip.

We are using BlueNRG2 chip for our BLE application. For the Information,We have connected 32MHz external crystal oscillator in HS Pins..We haven't connected any external crystal oscillator at LS Pins..And we haven't connected any inductor at SMPS pin...
